Apache Solr Release Notes

Release 9.8.1 [2025-03-11]

• Fixed   (9)
  • SOLR-17221: If multiple query param keys are sent that only vary by case, they were wrongly merged when doing distributed search (sharded collections). This could likely occur for fielded parameters such as f.CASE_SENSITIVE_FIELD.facet.limit=50.
    (Yue Yu, David Smiley)
  • SOLR-17587: Metrics: wt=prometheus fix for non-compliant exposition format containing duplicate TYPE lines.
    (Matthew Biscocho, David Smiley)
  • SOLR-17637: LBHttp2SolrClient can fail to complete async requests in certain error scenarios. This can cause the HttpShardHandler to indefinitely wait on a completed response that will never come.
    (Houston Putman)
  • SOLR-17644: Fixes collection creation failure when using a replica placement plugin with basic auth. SolrCloudManager now directly uses HttpSolrClientProvider's client, resolving missing auth listeners.
    (Sanjay Dutt, David Smiley)
  • SOLR-17649: Fix a regression of faceting on multi-valued EnumFieldType, introduced by an earlier 9.x version.
    (Thomas Wöckinger, David Smiley)
  • SOLR-17652: Fix a bug that could cause long leader elections to leave PULL replicas in DOWN state forever.
    (hossman)
  • SOLR-17670: Fix unnecessary memory allocation caused by a large reRankDocs param.
    (JiaBao Gao)
  • SOLR-17673: Disable multi-threaded search execution by default at the node-level. Users can still opt-in by providing a "indexSearcherExecutorThreads" > 0.
    (Houston Putman, Varun Thacker, David Smiley, Luke Kot-Zaniewski)
  • SOLR-17677: Before attempting a delete by query ("DBQ"), Solr now checks whether the provided query can be run using a Lucene IndexSearcher, and aborts the operation with a '400' error if it cannot.
    (Jason Gerlowski)

Release 9.8.0 [2025-01-23]

• Added   (3)
  • SOLR-17065: The Solr Cross-DC Project has graduated from the sandbox repository. It will now be released as a fully supported Solr feature. This feature closes SIP-13: Cross Data Center Replication.
    (Mark Miller, Anshum Gupta, Andrzej Bialecki, Jason Gerlowski, Houston Putman)
  • SOLR-17150: Implement `memAllowed` parameter to limit per-thread memory allocations during request processing.
    (Andrzej Bialecki, Gus Heck)
  • SOLR-17525: Added knn_text_to_vector query parser to encode text to vector at query time through external LLM services.
    (Alessandro Benedetti)
• Changed   (21)
  • SOLR-14985: Solrj CloudSolrClient with Solr URLs had serious performance regressions (since the beginning?) in which its collection state cache was not being used, resulting in many extra requests to Solr for cluster information.
    (Aparna Suresh, shalin, David Smiley)
  • SOLR-16390: v2 "cluster prop" APIs have been updated to be more REST-ful. Cluster prop creation/update are now available at `PUT /api/cluster/properties/somePropName`. Deletion is now available at `DELETE /api/cluster/properties/somePropName`. New APIs for listing-all and fetching-single cluster props are also now available at `GET /api/cluster/properties` and `GET /api/cluster/properties/somePropName`, respectively.
    (Carlos Ugarte, Jason Gerlowski)
  • SOLR-16470: Replication "fetch file" API now has a v2 equivalent, available at `GET /api/cores/coreName/replication/files/fileName`
    (Matthew Biscocho, Jason Gerlowski)
  • SOLR-17102: The VersionBucket indexing lock mechanism was replaced with something just as fast yet that which consumes almost no memory, saving 1MB of memory per SolrCore.
    (David Smiley)
  • SOLR-17158: Users using query limits (timeAllowed, cpuTimeAllowed) for whom partial results are uninteresting may set partialResults=false. This parameter has been enhanced to reduce time spent processing partial results and omit partialResults from the response. Since this is requested behavior, no exception is thrown and the partialResults response header will always exist if the result was short circuited.
    (Gus Heck, Andrzej Bialecki, hossman)
  • SOLR-17180: Deprecate snapshotscli.sh in favour of bin/solr snapshot sub commands. Now able to manage Snapshots from the CLI. HDFS module specific snapshot script now ships as part of that module in the modules/hdfs/bin directory.
    (Eric Pugh)
  • SOLR-17256: Deprecate SolrRequest `setBasePath` and `getBasePath` methods. SolrJ users wishing to temporarily override an HTTP client's base URL may use `Http2SolrClient.requestWithBaseUrl` instead.
    (Jason Gerlowski, Sanjay Dutt, David Smiley)
  • SOLR-17381: Make CLUSTERSTATUS request configurable to improve performance by allowing retrieval of specific information, reducing unnecessary data fetching. Enhanced CloudSolrClient's HTTP ClusterStateProvider to use it, and to scale to more collections better as well.
    (Aparna Suresh, David Smiley)
  • SOLR-17383: Resolved overlapping arguments in the Solr CLI. Removed duplicative but differing arguments, consolidated use of short form arguments -v to not have differing meanings based on tool. Provide deprecation warning in command line when deprecated arguments are used.
    (Eric Pugh, Christos Malliaridis)
  • SOLR-17390: EmbeddedSolrServer now considers the ResponseParser
    (David Smiley)
  • SOLR-17396: Reduce thread contention in ZkStateReader.getCollectionProperties().
    (Aparna Suresh, David Smiley, Paul McArthur)
  • SOLR-17397: SkipExistingDocumentsProcessor now functions correctly with child documents.
    (Tim Owens, Eric Pugh)
  • SOLR-17408: COLSTATUS command was fetching details remotely from replicas when this information wasn't asked for.
    (Mathieu Marie)
  • SOLR-17414: When searching with multiThreaded=true, the internal tasks may now block instead of enqueuing with a risk of rejection. Solr will use less resources under stress but to get the most of your machine, you may want to increase the thread pool.
    (David Smiley)
  • SOLR-17419: An alternate ShardHandlerFactory is now available, ParallelHttpShardHandlerFactory, which may help reduce distributed-search latency in collections with many shards, especially when PKI is used between nodes.
    (Jason Gerlowski)
  • SOLR-17441: Improve system metrics collection by skipping unreadable MXBean properties, making /admin/info/system calls faster
    (Haythem Khiri)
  • SOLR-17453: Leverage waitForState() instead of busy waiting in CREATE, MIGRATE, REINDEXCOLLECTION, MOVEREPLICA commands, and in some tests.
    (Pierre Salagnac)
  • SOLR-17528: Introduce -y short option to bin/solr start --no-prompt option. Aligns with bin/solr package tool.
    (Eric Pugh)
  • SOLR-17554: Suppress printing out of password to console when using auth CLI command.
    (Christos Malliaridis, Eric Pugh)
  • SOLR-17592: Switched from HTTP1 to HTTP2 in SolrCloudManager via HttpClient change from Apache to Jetty.
    (Sanjay Dutt, David Smiley)
  • SOLR-3913: Optimize PostTool to call just optimize when both commit and optimize requested.
    (Eric Pugh)
• Fixed   (16)
  • SOLR-11191: Splitting shards now routes child-docs with their _root_ field when available so they maintain parent relationship.
    (Zack Kendall)
  • SOLR-12429: Uploading a configset with a symbolic link produces a IOException. Now a error message to user generated instead.
    (Eric Pugh)
  • SOLR-16254: Clarify when a bin/solr create needs to be run on the same server as Solr.
    (Eric Pugh)
  • SOLR-16976: Remove log4j-jul jar and use slf4j bridge for JUL to prevent exception from being logged when remote JMX is enabled
    (Shawn Heisey, Stephen Zhou, Eric Pugh, Christine Poerschke, David Smiley)
  • SOLR-17306: fix replication problem on follower restart
    (Martin Anzinger, Peter Kroiss, Eric Pugh)
  • SOLR-17405: Fix race condition where Zookeeper session could be re-established by multiple threads concurrently in case of frequent session expirations.
    (Pierre Salagnac)
  • SOLR-17413: Fixed UpdateLog replay bug that shared thread-unsafe SolrQueryRequest objects across threads
    (Jason Gerlowski, David Smiley, Houston Putman)

    (Jason Gerlowski, James Dyer)
  • SOLR-17529: Clean up error message in PostTool when you attempt to post to a basic auth secured Solr.
    (Eric Pugh)
  • SOLR-17574: Fix AllowListUrlChecker when liveNodes changes. Remove ClusterState.getHostAllowList
    (Bruno Roustant, David Smiley)
  • SOLR-17575: Fixed broken backwards compatibility with the legacy "langid.whitelist" config in Solr Langid.
    (Jan Høydahl, Alexander Zagniotov)
  • SOLR-17586: Print zkcli.sh deprecation msg to stderr, which fixes Solr Operator upload of security.json to zookeeper
    (Jan Høydahl)
  • SOLR-17595: Fix two issues in Solr CLI that prevent Solr from starting with the techproducts example and from correctly parsing arguments on Windows that start with -D and have multiple values separated by "," or spaces.
    (Christos Malliaridis)
  • SOLR-6962: bin/solr stop/start/restart should complain about missing value for options that expect a value.
    (Eric Pugh, Rahul Goswami)

    (David Smiley)
  • SOLR-16781: "<lib/>" tags in solrconfig.xml are now quietly ignored by default unless explicitly enabled with the `SOLR_CONFIG_LIB_ENABLED=true` enviroment variable (or corresponding sysprop). These tags are now considered deprecated and will be removed in Solr 10.

Release 9.7.0 [2024-09-09]

• Added   (8)
  • SOLR-10255: Add support for docValues to solr.BinaryField.
    (Alexey Serba, Mikhail Khludnev, David Smiley)
  • SOLR-10654: Introduce output of Prometheus metrics directly from Solr.

    (Ishan Chattopadhyaya, Mark Miller, Christine Poerschke, David Smiley, noble, Gus Heck)
  • SOLR-17192: Put an UpdateRequestProcessor-enforced soft-limit on the number of fields allowed in a core. The `NumFieldLimitingUpdateRequestProcessorFactory` limit may be adjusted by raising the factory's `maxFields` setting, toggled in and out of "warning-only" mode using the `warnOnly` setting, or disabled entirely by removing it solrconfig.xml. The limit is set at 1000 fields in the "_default" configset, but left in warning-only mode.
    (David Smiley, Eric Pugh, Jason Gerlowski)
  • SOLR-17195: Configsets now include a `minPrefixQueryTermLength` setting, which instructs Solr to reject prefix queries whose prefixes are "too short". This can be used as one line of defense against "runaway wildcard queries" consuming too many resources. The setting is disabled ('-1') in the default configset but can be overridden with a property ('solr.query.minPrefixLength'). Users may also override their collection-wide setting for individual queries by providing a `minPrefixQueryTermLength` local-param.
    (Jason Gerlowski, David Smiley)
  • SOLR-17276: Prometheus Exporter: now scrapes metrics at a fixed rate instead of delay.
    (Rafał Harabień)
  • SOLR-17277: Circuit breakers may now be configured in a "soft" or "warnOnly" mode in order to more easily test out new thresholds. Soft breakers will log out a message on each relevant request when tripped, but will not otherwise impact or short circuit the requests.
    (Jason Gerlowski)
  • SOLR-17335: New "vectorSimilarity" QParser for matching documents mased on a minimum vector similarity threshold.
    (hossman)
• Changed   (22)
  • SOLR-10808: The Solr schema version has been increased to 1.7. Since schema version 1.7, all fields/fieldTypes that support docValues will have them enabled by default. This behavior can be reverted by setting 'docValues' parameter for a field or a field type to false, the default for schema versions 1.6 and below.
    (Houston Putman)
  • SOLR-14115: Add linkconfig, cluster, and updateacls as commands to SolrCLI. Allow bin/solr commands to have parity with zkcli.sh commands.
    (Eric Pugh)
  • SOLR-15591: Make using debugger in Solr easier by avoiding NPE in ExternalPaths.determineSourceHome.
    (, Eric Pugh)
  • SOLR-16198: Introduce tabbed sections again in the Ref Guide.
    (Christos Malliaridis, Eric Pugh)
  • SOLR-16677: Update Solr to use new Lucene 9.5 storedFields() API. This removes the use of ThreadLocal for stored field state, reducing heap usage especially for high-core-count, high-field-count, high-thread-count cases
    (Vinayak Hegde, Christine Poerschke, Kevin Risden, David Smiley, Michael Gibney)
  • SOLR-16824: Adopt Linux standard pattern of -- for long option commands, and make all commands "kebab" formatting. I.e -zkHost is now -zk-host. The old parameters such as -zkHost continue to be supported in the 9.x line of Solr. -u is now used to specify user credentials everywhere, this only impacts the bin/solr assert commands "same user" check which has -u as the short form of --same-user.
    (Eric Pugh, janhoy, Jason Gerlowski, Christos Malliaridis)
  • SOLR-16921: use -solrUrl to derive the zk host connection for bin/solr zk subcommands
    (Eric Pugh)

    (Tomás Fernández Löbbe, Eric Pugh)
  • SOLR-17137: Enable Prometheus exporter to communicate with SSL protected Solr.
    (Eivind Bergstøl, Eric Pugh)
  • SOLR-17160: Core Admin "async" request status tracking is no longer capped at 100; it's 10k. Statuses are now removed 5 minutes after the read of a completed/failed status. Helps collection async backup/restore and other operations scale to 100+ shards.
    (Pierre Salagnac, David Smiley)
  • SOLR-17257: Both Minimize Cores and the Affinity replica placement strategies would over-gather cluster metrics. AttributeFetcherImpl was improved accordingly.
    (Yohann Callea)
  • SOLR-17269: Prevent the "Coordinator node" feature from registering synthetic cores in ZooKeeper [SOLR-17386](https://issues.apache.org/jira/browse/SOLR-17386)
    (ellaeln, Patson Luk, David Smiley, Christine Poerschke)
  • SOLR-17274: Allow JSON atomic updates to use multiple modifiers or a modifier like 'set' as a field name if child docs are not enabled.
    (Calvin Smith, David Smiley)
  • SOLR-17300: Http2SolrClient.Builder.withHttpClient now copies HttpListenerFactory
    (e.g. for auth, metrics, traces, etc., Sanjay Dutt, David Smiley)
  • SOLR-17330: When not set, loadOnStartup defaults to true, which is the default choice for a core.
    (Pierre Salagnac, Eric Pugh)
  • SOLR-17331: OrderedNodePlacementPlugin will give an even more optimal replica placements during ReplicaMigration commands
    (Houston Putman, Yohann Callea)
  • SOLR-17340: Add cache on top of system metrics BeanInfos to make calls to /admin/info/system faster
    (Pierre Salagnac)
  • SOLR-17346: Synchronise stopwords from snowball with those in Lucene
    (Alastair Porter, Houston Putman)

    (Houston Putman, Liu Huajin)
  • SOLR-17434: Avoid exposing Solr's IP in the Location header.
    (David Smiley)
• Fixed   (18)
  • PR#2475: PR-2475: Fixed node listing bug in Admin UI when different hostnames start with the same front part.
    (, Eric Pugh)
  • SOLR-12813: subqueries should respect basic auth.
    (Rudy Seitz, Eric Pugh)
  • SOLR-16659: Properly construct V2 base urls instead of replacing substring "/solr" with "/api"
    (Andrey Bozhko, Eric Pugh)
  • SOLR-16962: Restore ability to configure tlog directory. Changes largely focus on UpdateLog and HdfsUpdateLog. There is no anticipated change in existing behavior, other than that the `dir` parameter to the `<updateLog>` element in `solrconfig.xml`, which has long been silently ignored, will now be respected
    (Michael Gibney, David Smiley)
  • SOLR-17118: Simplify CoreContainerProvider initialization and JettySolrRunner. Avoid deadlock/hang.
    (David Smiley)
  • SOLR-17247: 'WWW-Authenticate' headers missing in MultiAuthPlugin

    (hossman)
  • SOLR-17391: Fixed performance regression of misconfigured threadpools from SOLR-16879 (Solr 9.4). Shard splits and concurrent/large collection backup/restore performance was serial. UpdateLog replay was a little suboptimal in thread usage too. [SOLR-16879](https://issues.apache.org/jira/browse/SOLR-16879)
    (Pierre Salagnac, Hakan Özler, David Smiley)

    (David Smiley)
  • SOLR-15831: Refactor bin/solr and bin/solr.cmd commands integration with AuthTool, DeleteTool, and PackageTool to delegate arg parsing to Java code. Removed limitation of PackageTool only being executed on an active Solr node.

    (Vincent Primault)
  • SOLR-17084: LBSolrClient (used by CloudSolrClient) now returns the count of core tracked as not live AKA zombies instead of the full list of cores. This list is potentially as long as the number of cores. When there are many cores, this leads to high CPU and memory usage.

Release 9.3.0 [2023-07-21]

• Upgrade Notes   (1)
  • SOLR-13396: Add property to control the deletion of unknown cores. The default setting is to not delete unknown cores. This is a change to behaviour introduced in Solr 7.3.1 by SOLR-12066. To continue using the previous behaviour, Solr can be started with the system property `solr.deleteUnknownCores` set to `true`. [SOLR-12066](https://issues.apache.org/jira/browse/SOLR-12066)
    (Colvin Cowie, janhoy)
• Added   (14)
  • SOLR-16674: Introduced support for byte vector encoding in DenseVectorField and KnnQParser
    (Elia Porciani, Alessandro Benedetti)
  • SOLR-16675: Added function queries for dense vector similarity.
    (Elia Porciani, Alessandro Benedetti)
  • SOLR-16697: Solr now provides an "Install Shard" API that allows users who have built (per-shard) indices offline to import them into SolrCloud shards. The API is available at `POST /api/collections/collName/shards/shardName/install` (v2), or at `GET /solr/admin/collections?action=INSTALLSHARDDATA` (v1).
    (Jason Gerlowski)
  • SOLR-16717: {!join} can join collections with multiple shards on both sides.
    (Mikhail Khludnev)
  • SOLR-16719: AffinityPlacementFactory now supports spreading replicas across domains within the availability zone and optionally fail the request if more than a configurable number of replicas need to be placed in a single domain.
    (Houston Putman, Tomás Fernández Löbbe)
  • SOLR-16742: Produce a slim Solr binary and docker image, without the Prometheus Exporter and Solr Modules.
    (Houston Putman)
  • SOLR-16806: Solr now provides a BalanceReplicas API at `POST /api/cluster/replicas/balance` (v2), to spread replicas across a given set of nodes. No v1 API is available.
    (Houston Putman, Tomás Fernández Löbbe, Jason Gerlowski, Radu Gheorghe)
  • SOLR-16812: Support CBOR format for update/query
    (noble)
  • SOLR-16827: Add min/max scaling to the reranker
    (Joel Bernstein)
  • SOLR-16836: Introduced support for high dimensional vectors
    (Alessandro Benedetti)
  • SOLR-16837: Introducing AffinityPlacementFactory.withCollectionShards to collocate corresponding shards of two collections. eg primaryColl.shard1 will be placed to the node where secondaryColl.shard1 resides, etc.
    (Mikhail Khludnev)
  • SOLR-16844: Added new parameter `backupConfigset` to collection Backup to optionally skip backing up configsets.
    (Tomás Fernández Löbbe)
  • SOLR-16855: Solr now provides a MigrateReplicas API at `POST /api/cluster/replicas/migrate` (v2), to move replicas off of a given set of nodes. This extends the functionality of the existing ReplaceNode API.
    (Houston Putman)
  • SOLR-16884: Solr Javadocs now have searching enabled.
    (Mike Drob, Houston Putman)
• Changed   (44)
  • SOLR-10466: Introduce Builder setter for defaultCollection on cloud SolrClients. Deprecated direct setter setDefaultCollection on cloud SolrClients.
    (Eric Pugh, David Smiley)
  • SOLR-14630: When querying with the `_route_` or `shards.preference` parameter and if there are multiple replicas for a collection on the receiving node, there was sometimes an extra HTTP hop or the non-intended replica may receive the request. SolrJ will now form the URL directly to the intended replica of the collection (and not the collection itself).
    (Pierre Salagnac, Ivan Djurasevic, Jason Baik)
  • SOLR-14853: Security: Converted enableRemoteStreaming and enableStreamBody solrconfig options into system properties and env vars. Attempts to set them the old way are no-op and log a warning.
    (David Smiley, janhoy, Ishan Chattopadhyaya)
  • SOLR-15493: Throw an error message if the feature store doesn't exist.
    (Ilaria Petreti, Alessandro Benedetti)
  • SOLR-15737: Solr's collection-level "snapshot" APIs now have v2 equivalents. Snapshots can be created at `POST /api/collections/collName/snapshots/snapshotName`, listed at `GET /api/collections/collName/snapshots`, and deleted at `DELETE /api/collections/collName/snapshots/snapshotName`.
    (John Durham, Jason Gerlowski)
  • SOLR-16183: XML update allows <doc> <doc name="child"> ... </doc> </doc>.
    (Vinayak Hegde, Mikhail Khludnev)
  • SOLR-16273: Improve the performance of the Prometheus Metric Exporter scraping metrics
    (Matthew Biscocho, David Smiley & Christine Poerschke)
  • SOLR-16391: Solr's v2 "create collection" API has been tweaked slightly to be more intuitive. It remains available under `POST /api/collections`, but the top level "create" command-name key has been removed.
    (Jason Gerlowski)
  • SOLR-16391: The path of the v2 "collprop" API has been tweaked slightly to be more intuitive. Endpoints are now available under the `PUT` and `DELETE` verbs at `/api/collections/collName/properties/propName` depending on whether the property is being upserted or deleted.
    (Jason Gerlowski)
  • SOLR-16392: The v2 "add-replica" API has been tweaked to be more intuitive, by removing the top-level command specifier and changing the path. The v2 functionality can now be accessed at: `POST /api/collections/cName/shards/sName/replicas {...}`
    (Jason Gerlowski)
  • SOLR-16392: The v2 "create shard" API has been tweaked to be more intuitive, by removing the top-level "create" command specifier. The rest of the API remains unchanged.
    (Jason Gerlowski)
  • SOLR-16392: The v2 deletereplica API has been tweaked to be more intuitive: single replicas deletion now uses `DELETE /api/collections/cName/shards/sName/replicas/rName`, deletion of multiple relicas in a single shard uses `DELETE /api/collections/cName/shards/sName/replicas?count=123`, and deletion of multiple replicas from all shards now uses `PUT /api/collections/cName/scale {"count": 123"}`
    (Jason Gerlowski)
  • SOLR-16393: Solr's v2 "aliasprop" CRUD APIs have been tweaked slightly to be more intuitive. Alias property modification is now available at `PUT /api/aliases/aliasName/properties` (for bulk modification) and `PUT /api/aliases/aliasName/properties/propName` (for single property updates). Additionally new APIs have been added for listing properties (`GET /api/aliases/aliasName/properties`), fetching single property values (`GET /api/aliases/aliasName/properties/propName`), and property deletion (`DELETE /api/aliases/aliasName/properties/propName`).
    (Alex Deparvu, Jason Gerlowski)
  • SOLR-16393: The path of the v2 "delete alias" API has been tweaked slightly to be more intuitive, and is now available at `DELETE /api/aliases/aliasName`.
    (Jason Gerlowski)
  • SOLR-16393: The v2 "create alias" API has been tweaked to be more intuitive. The format of the request body has changed slightly: the "create-alias" command specifier has been removed, the "name" field for individual routers has been renamed to "type", and the routers themselves are now always grouped into a list. Additionally the v2 API has moved to the new path `POST /api/aliases`.
    (Jason Gerlowski)
  • SOLR-16394: The path of the v2 "collection backup" API has been tweaked slightly to be more intuitive, and is now available at `POST /api/collections/backups/backupName/versions`.
    (Jason Gerlowski)
  • SOLR-16394: The v2 "restore" API has been tweaked to be more intuitive. The top-level "restore-collection" command specifier has been removed, and the API now lives at the new path `POST /api/backups/backupName/restore`.
    (Jason Gerlowski)
  • SOLR-16394: The v2 list and delete (collection) backup APIs have been tweaked to be more intuitive: backup listing now uses `GET /api/backups/bName/versions`, backup deletion by ID now uses `DELETE /api/backups/bName/versions/1`, backup deletion by recency now uses `DELETE /api/backups/bName/versions?retainLatest=3`, and index-file "garbage collection" now uses `PUT /api/backups/backupName/purgeUnused`
    (Jason Gerlowski)
  • SOLR-16397: Reload core v2 endpoints have been updated to be more REST-ful. RELOAD is now available at `POST /api/cores/coreName/reload`
    (Sanjay Dutt, Jason Gerlowski)
  • SOLR-16397: Unload core v2 endpoints have been updated to be more REST-ful. UNLOAD is now available at `POST /api/cores/coreName/unload`
    (Sanjay Dutt, Jason Gerlowski)
  • SOLR-16398: Several v2 "command" APIs have been tweaked to be more intuitive. "FORCELEADER" is now available at `POST /api/collections/cName/shards/sName/force-leader`, "RELOAD" is now available at `POST /api/collections/cName/reload`, "SYNCSHARD" is now available at `POST /api/collections/cName/shards/sName/sync-shard`, and "RENAME" is now available at `POST /api/collections/cName/rename`.
    (Jason Gerlowski)
  • SOLR-16398: The v2 "balance-shard-unique" API has been tweaked to be more intuitive, by removing the top-level command specifier from the request body, and changing the path. The v2 functionality can now be accessed at: `POST /api/collections/cName/balance-shard-unique {...}`
    (Jason Gerlowski)
  • SOLR-16458: Solr's v2 "logging" APIs have been tweaked slightly to be more intuitive. The single v2 endpoint that existing previously (GET /api/node/logging) has been split into several different APIs. Logger levels can be fetched or modified at `GET /api/node/logging/levels` and `PUT /api/node/logging/levels`, respectively. Log messages can be returned from a "listener" at `GET /api/node/logging/messages`. And the threshold for the log "listener" can be modified with `PUT /api/node/logging/messages/threshold`.
    (Jason Gerlowski, Calvince Otieno)
  • SOLR-16470: `/coreName/replication?command=filelist` now has a v2 equivalent, available at `GET /api/cores/coreName/replication/files?generation=123`
    (Matthew Biscocho, Jason Gerlowski)
  • SOLR-16470: `/coreName/replication?commit=indexversion` now has a v2 equivalent, available at `GET /api/cores/coreName/replication/indexversion`

    (Bence Szabo, Eric Pugh)
  • SOLR-16687: Add support of SolrClassLoader to SolrZkClient
    (Lamine Idjeraoui, Jason Gerlowski & Houston Putman)
  • SOLR-16692: Allow setting the a CookieStore implementation in Http2SolrClient. When Cookies are not needed, this can be set to `org.eclipse.jetty.util.HttpCookieStore.Empty`, which avoids some of the processing that happens in the default `java.net.InMemoryCookieStore`. Solr can also be started with the system property `solr.http.disableCookies` set to `true`, so that the internal clients that Solr uses to communicate between nodes use `HttpCookieStore.Empty`.
    (Tomás Fernández Löbbe)
  • SOLR-16693: For query timeAllowed, switch from ExitableDirectoryReader to TimeLimitingBulkScorer
    (David Smiley)
  • SOLR-16694: Shortcut Http2SolrClient mimeType check for default response parse
    (Tomás Fernández Löbbe, Alex Deparvu)
  • SOLR-16711: Extract SolrCLI tool implementations into their own classes and reorganize CLI related classes into new org.apache.solr.cli package.
    (Eric Pugh)
  • SOLR-16748: The Official Solr Dockerfile has been cleaned up. The SOLR_DOWNLOAD_SERVER arg is now the only way to specify where to download Solr from. If the url includes "apache.org", then GPG checks will be computed, otherwise the GPG checks will be skipped.
    (Houston Putman)
  • SOLR-16752: Docker: Leave out optional apt packages, slightly reducing image size and lowering attack surface
    (Quang-Cuong Bui)
  • SOLR-16759: Introducing logAll parameter in the feature logger
    (Anna Ruggero, Alessandro Benedetti)
  • SOLR-16764: Clarify that ExportTool exports documents in JSON with Lines format, not standard JSON. Add explicit -compress option for gzipping output. Add ability to specific a directory for output along with a specific file when using -out.
    (Eric Pugh)
  • SOLR-16766: Remove -usage as option from bin/solr, and ensure both -help and -h work.
    (Bence Szabo, Eric Pugh)
  • SOLR-16782: bin/solr export tool now supports JSON export format as well as the existing JSON With Lines format.
    (Eric Pugh)
  • SOLR-16806: The included PlacementPlugins (Random, Simple, MinimizeCores and Affinity) now all implement the OrderedNodePlacementPlugin, which provides the implementation for computePlacements() and computeBalancing(). Each implementing PlacementPlugin provides a way of weighting Solr Nodes, and the OrderedNodePlacement plugin then uses the weights to decide the optimal strategy for placing new replicas or balancing existing replicas.
    (Houston Putman, Tomás Fernández Löbbe, Jason Gerlowski, Radu Gheorghe)
  • SOLR-16816: Update node metrics while making affinityPlacement selections. Therefore selections can be made given the expected cluster information after the previous selections are implemented.
    (Houston Putman)
  • SOLR-16820: Align allowed collection names and the validation of them in the CreateCollectionAPI and the PackageTool.
    (Will White, Eric Pugh)
  • SOLR-16846: Use IndexOrDocValuesQuery for PointFields on Set queries. This improves the performance in some scenarios when the set query is combined with other selective queries.
    (Tomás Fernández Löbbe, Alex Deparvu)
  • SOLR-16869: Enable Incubating Java Panama Vector APIs when using Java 20 or 21. When run using compatible hardware, Vector search will see considerable speed up.
    (Houston Putman, Uwe Schindler)
  • SOLR-16878: Use Log4J JUL manager when starting Java. This is necessary for Lucene logs to be included with Solr logs.
    (Houston Putman, Uwe Schindler)
  • SOLR-9378: Internal shard requests no longer include the wasteful shard.url param. [shard] transformer now defaults to returning only the shard id (based on luceneMatchVersion), but can be configured to return the legacy list of replicas.
    (hossman)

    (Nazerke Seidan, David Smiley)
  • SOLR-16158: Certain Jetty "server" jars (jetty-util, jetty-io, etc.) are no longer duplicated between server/lib and WEB-INF/lib. All shared jars now live in server/lib/ext. By default, Jetty does not allow these jars to be shared by the Jetty server and the web-app (Solr). In order to accomplish this, explicit exclusions have been added to server/contexts/solr-jetty-context.xml that allow these "server" jars to be shared. Solr Core also no longer contains the JettySolrRunner (now living in the testing framework), removing the need for Jetty Server dependencies in solr-core.
    (Houston Putman)

  • SOLR-16393: The path of the v2 "list alias" API has been tweaked slightly to be more intuitive, and is now available at `GET /api/aliases`. It is also now possible to request information about a specific alias at `GET /api/aliases/<aliasName>`.
    (Alex Deparvu, Jason Gerlowski)
  • SOLR-16397: /mlt now has a v2 API available at `GET /api/collections/collName/mlt`

    (Mikhail Khludnev)
  • SOLR-16428: IgnoreLargeDocumentProcessorFactory now supports a "permissive" mode, where it logs and skips offending documents but doesn't short-circuit the entire batch or return a 4xx error. This mode can be enabled by setting the `permissiveMode` boolean option to `true` in your solrconfig.xml's IgnoreLargeDocumentProcessorFactory declaration.
    (Jason Gerlowski)
  • SOLR-16462: v2 equivalents of the "Core Admin" `LISTSNAPSHOT`, `CREATESNAPSHOT`, and `DELETESNAPSHOT` commands are now available at `GET /api/cores/coreName/snapshots`, `POST /api/cores/coreName/snapshots/snapshotName`, and `DELETE /api/cores/coreName/snapshots/snapshotName`, respectively
    (John Durham, Jason Gerlowski)
  • SOLR-16475: Make the default replica placement plugin configurable as system property on startup
    (janhoy)
  • SOLR-16487: Replication pooling is optimized based on hard and soft commit settings for a given collection
    (Justin Sweeney)

    (noble)
  • SOLR-16590: Standardize Builder method names on SolrClient's to use the with pattern, deprecating the use of set or bare property name.
    (Eric Pugh)
  • SOLR-16595: Standardize Builder methods handling of times to use require a TimeUnit to be passed in. Deprecated methods that do not specify a TimeUnit.
    (Eric Pugh)

    (Tomás Fernández Löbbe)
  • SOLR-16665: The base docker image has been upgraded from Ubuntu 20 (Focal) to Ubuntu 22 (Jammy).
    (Houston Putman)
  • SOLR-16689: Avoiding commits on leader when recovering a non-leader replica and avoiding incorrectly replicating an empty core
    (Justin Sweeney)
  • SOLR-6312: SolrJ Cloud clients now correctly support isUpdatesToLeaders() being false. This behavior can also be configured per AbstractUpdateRequest instance.
    (hossman)
  • SOLR-8803: Java will now crash the Solr process on OOME and create a crash file that logs the cause. This capability is now also present on Windows. Before, with bin/solr but not bin/solr.cmd, Solr would execute a script that killed the Solr pid, leaving a very small time window where Solr would continue to execute in an unpredictable state.
    (Shawn Heisey, Kevin Risden)
  • SOLR-8975: Introduce Builder setters for setters that exist on SolrClients for responseParser, requestWriter. Deprecated these SolrClient setters useMultiPartPost, and followRedirects.

The parameters and configuration of the module extensions have changed. The documentation in Solr ref guide has been rewritten from scratch to be up to date. Clustering code has been rewritten from scratch to work properly regardless of the mode (standalone, distributed). The API has been stripped of ancient, unused, interfaces and simplified. [SOLR-13506](https://issues.apache.org/jira/browse/SOLR-13506)

    (Collins Abanda, Mike Drob, Tim Potter, David Smiley, Michael Gibney)

  • SOLR-14590: Add support for RankFields. RankFields allow the use of per-document scoring factors in a way that lets Solr skip over non-competitive documents when ranking. See SOLR-13289. [SOLR-13289](https://issues.apache.org/jira/browse/SOLR-13289)
    (Tomás Fernández Löbbe, Varun Thacker)

    (Gus Heck)
  • SOLR-13289: When the "minExactCount" parameters is provided in queries and it's value is lower than the number of hits, Solr can speedup the query resolution by using the Block-Max WAND algorithm (see LUCENE-8135). When doing this, the value of matching documents in the response (numFound) will be an approximation. [LUCENE-8135](https://issues.apache.org/jira/browse/LUCENE-8135)
    (Ishan Chattopadhyaya, Munendra S N, Tomás Fernández Löbbe, David Smiley)
  • SOLR-13325: ComputePlanAction now supports a collection selector of the form `collections: {policy: my_policy}` which can be used to select multiple collections that match collection property/value pairs.

Release 8.4.1 [2020-01-13]

• Upgrade Notes   (1)
  • SOLR-14158: Package manager now stores keys in package store instead of ZK. If you're using package manager and have already added any repositories, then you would need to re-add all the keys from /keys/exe location, one-by-one, using: "bin/solr add-key <keyfile.der>"
• Changed   (1)
  • SOLR-14158: Package manager to store public keys in a special "trusted" location instead of in ZooKeeper

    (Andy Webb, noble)

Release 8.4.0 [2019-12-29]

• Upgrade Notes   (11)
  • SOLR-13806: QueryResponse.getExplainMap() type has changed from Map<String, String> to Map<String, Object> in order to accommodate structured explanations. This is a partially back-compatible change - compiled third-party components will work the same as before due to type erasure but source code changes may be required.
  • SOLR-13817: Deprecate legacy SolrCache implementations. Users are encouraged to transition their configurations to use org.apache.solr.search.CaffeineCache instead.
    (ab)
  • SOLR-13823: org.apache.solr.search.grouping.distributed.command.QueryCommand.Builder has new method 'setMainQuery' which is used to set top-level query. build() would fail if called without setting mainQuery.
  • SOLR-13904: timeAllowed parameter is allowed to have 0 value
    (Houston Putman, Mikhail Khludnev)
  • SOLR-13970: Using Collapse filter or expand component with grouping is explicitly disallowed as the combination would cause inconsistent behavior and NPEs.
  • SOLR-13978: The default configset no longer has the following: - Library inclusions (<lib ../>) for extraction, solr-cell libs, clustering, velocity, LTR and language identifier - /browse, /tvrh and /update/extract handlers - TermVector component
    (if someone wants it, can be added using config APIs)
  • SOLR-13982: Some security-related http headers such as Content-Security-Policy are now set. If you have custom html served up by Solr's http server that contains inline javascript, it will no longer execute in modern browsers. You can fix your JS code to not run inline anymore, or edit etc/jetty.xml and weaken the CSP, or remove/alter the headers with a reverse proxy.
    (rmuir)
  • SOLR-14025: VelocityResponseWriter has been hardened - only trusted configsets can render configset provided templates and rendering templates from request parameters has been removed.
  • SOLR-14065: VelocityResponseWriter has been deprecated and may be removed in a future version.
  • SOLR-14071: Untrusted configsets (ones that are uploaded via unsecured configset API) cannot use <lib> directive. Consider enabling authentication/authorization so that the uploaded configsets are trusted. Note: If you already have a collection using untrusted configset that uses <lib> directive, it will not load after upgrading to 8.4. You can re-upload your configset using "bin/solr zk -upconfig .." or place your libraries in the classpath and restart Solr.
  • SOLR-14072: The "Blob Store" API and "runtimeLib" plugin mechanism that uses it is now considered deprecated. The replacement to it is the "Package Management" system, which includes a "File Store". These are experimental currently but will grow/stabalize/mature.
• Added   (9)
  • SOLR-10786: Add DBSCAN clustering Streaming Evaluator
    (Joel Bernstein)
  • SOLR-12217: Support shards.preference in SolrJ for single shard collections. The parameter is now used by the CloudSolrClient and Streaming Expressions.

    (noble, Ishan Chattopadhyaya)
  • SOLR-13822: A Package management system with the following features: (a) A packages.json in ZK to store the configuration, (b) APIs to read/edit them, and (c) Isolated classloaders to load the classes from those packages when the 'class' attribute is prefixed with '<package-name>:'

    (Martijn Koster, Jason Gerlowski)
  • SOLR-13207: In dismax and edismax "minimum should match" queries, the < operator not followed by a number will now return an HTTP 400 error rather than 500, and the error message will explain that < must be followed by a number.

  • SOLR-13790: LRUStatsCache size explosion and ineffective caching.
    (ab)
  • SOLR-13793: HttpSolrCall now maintains internal request count (_forwardedCount) for remote queries and limits them to the number of replicas. This avoids making too many cascading calls to remote servers, which, if not restricted, can bring down nodes containing the said collection
    (Kesharee Nandan Vishwakarma, Ishan Chattopadhyaya)
  • SOLR-13802: Managed schema manipulations were not persisting the optional luceneMatchVersion that can be set on an Analyzer.
    (Thomas Wöckinger)
  • SOLR-13815: Live shard split (where updates actively continue during the split) can lose updates due to cluster state happening to change between checking if the current shard is active and later checking if there are any sub-shard leaders to forward the update to.

    (Amrit Sarkar, shalin)
  • SOLR-13855: DistributedZkUpdateProcessor should have been propagating URP.finish() lifecycle like it used to before 8.1 (a regression). Impacts integrity since Run URP's finish() propagates this to the updateLog to fsync.

Release 8.2.0 [2019-07-26]

• Upgrade Notes   (6)
  • SOLR-13419: Time Routed Aliases now have a '__TRA__' infix preceding the timestamp portion of the collection names. collections with the old format will not be altered and will continue to work, but any new TRA's or new collections for existing TRA's will use the new format. Solr will handle this invisibly, but any external code that attempted to predict collection names in TRA's will probably need adjustment.
  • SOLR-13420: Routed Aliases now use collection properties rather than core properties to identify collections that belong to the alias by default. This should be invisible and fully backwards compatible from within solr, and existing routed alias collections with core based properties will continue to work, but new collections created will not add a property to core.properties anymoore so any external code that inspected core.properties will not find the 'routedAliasName' key in new cores belonging to routed aliases.
  • SOLR-13507: Support for "addr" parameter from the "/solr/admin/zookeeper" endpoint has now been removed and will no longer be supported.
  • SOLR-13515: org.apache.solr.util.SolrPluginUtils.IdentityRegenerator has been removed, please use the identical org.apache.solr.search.NoOpRegenerator instead.

Release 8.1.1 [2019-05-28]

• Fixed   (1)
  • SOLR-13475: Null Pointer Exception when querying collection through collection alias.
    (Jörn Franke, ab)

Release 8.1.0 [2019-05-16]

• Upgrade Notes   (8)
  • SOLR-12708: When requesting the status of an async request via REQUESTSTATUS collections API, the response will include the list of internal async requests (if any) in the "success" or "failed" keys (in addition to them being included outside those keys for backwards compatibility). See SOLR-12708 for more details
  • SOLR-13335: Velocity and Velocity Tools were both upgraded as part of this release. Velocity upgraded from 1.7 to 2.0. Please see https://velocity.apache.org/engine/2.0/upgrading.html about upgrading. Velocity Tools upgraded from 2.0 to 3.0. For more details, please see https://velocity.apache.org/tools/3.0/upgrading.html for details about the upgrade.
  • SOLR-13336: Solr's default behavior when dealing with 'maxBooleanClauses' has changed to reduce the risk of exponential query expansion when dealing with pathological query strings. A default upper limit of 1024 clauses (The same default prior to Solr 7.0) is now enforced at the node level, and can be overridden in solr.xml. The identically named solrconfig.xml setting is still available for limiting the size of 'explicit' boolean query strings, but this per-collection limit is still ristricted by the upper-bound of the global limit in solr.xml. See SOLR-13336 for more details.
  • SOLR-13394: The default GC has been changed from CMS to G1. To override this (in order to switch to CMS or any other GC), use GC_TUNE section of bin/solr.in.sh or bin/solr.in.cmd.
  • SOLR-13400: Custom TransientSolrCoreCache implementations no longer use the Observer/Observable pattern. To notify Solr that a core has been aged out of the cache, call CoreContainer.queueCoreToClose(SolrCore). See SOLR-13400 for details.
  • SOLR-13407: Update requests sent to non-routed aliases that point to multiple collections are no longer accepted. Until now Solr followed an obscure convention of updating only the first collection from the list, which usually was not what the user intended. This change explicitly rejects such update requests.
  • SOLR-5970: Until now, the CREATE command of Collections API returned status 0 even in case of failure. Now, the status code will be non-zero in case of failures
    (e.g. 4xx, 5xx)
  • SolrGangliaReporter has been removed from Solr because support for Ganglia has been removed from Dropwizard Metrics 4 due to a transitive dependency on LGPL.
• Added   (16)
  • SOLR-10436: Add hashRollup Streaming Expression
    (Joel Bernstein)
  • SOLR-11127: REINDEXCOLLECTION command for re-indexing of existing collections. This issue also adds a back-compat check of the .system collection to notify users of potential compatibility issues after upgrades or schema changes.

    (janhoy)
  • SOLR-12121: JWT Token authentication plugin with OpenID Connect implicit flow login through Admin UI
    (janhoy)
  • SOLR-12638: Partial/Atomic Updates for nested documents. This enables atomic updates for nested documents, without the need to supply the whole nested hierarchy (which would be overwritten if absent). This is done by fetching the whole document hierarchy, updating the specific doc in the path that is to be updated, removing the old document hierarchy and indexing the new one with the atomic update merged into it. Also, [child] Doc Transformer now works with RealTimeGet.
    (Moshe Bla, David Smiley)
  • SOLR-13131: Category Routed Aliases are now available for data driven assignment of documents to collections based on values of a field. The Ref Guide now has a page dedicated to explaining the different types of aliases.
    (Gus Heck, Moshe Bla)
  • SOLR-13171: A true streaming parser for javabin payload/stream without creating any objects
    (noble)
  • SOLR-13261: Make SortableTextField work with export/streaming. NOTE: requires that the field have useDocValuesAsStored=true

  • SOLR-11473: Make HDFSDirectoryFactory support other prefixes
    (besides hdfs:/, Kevin Risden)
  • SOLR-12167: Throw an exception, instead of just a warning, when unknown atomic update operation is encountered
    (Munendra S N, Ishan Chattopadhyaya)
  • SOLR-12833: Avoid unnecessary memory cost when DistributedUpdateProcessor timed-out lock is not used.
    (jefferyyuan, ab)

  • SOLR-13398: Move log line "Processing SSL Credential Provider chain..." from INFO to DEBUG
    (janhoy)
  • SOLR-13407: Reject update requests sent to non-routed multi collection aliases.
    (ab)
  • SOLR-13432: Add .toString methods to BitDocSet and SortedIntDocSet so that enabling "showItems" on the filter caches shows some useful information about the values in the cache.
    (shalin)
  • SOLR-9079: Remove commons-lang as a dependency
    (Kevin Risden)
• Fixed   (38)
  • SOLR-11876: In-place update fails when resolving from Tlog if schema has a required field
    (Justin Deoliveira, janhoy, Ishan Chattopadhyaya)

    (Erick Ericsson, Adrien Grand, Munendra S N, Scott Stults, Ishan Chattopadhyaya)
  • SOLR-12291: prematurely reporting not yet finished async Collections API call as completed when collection's replicas are colocated at least at one node
    (Varun Thacker, Mikhail Khludnev)
  • SOLR-12330: 500 error code on json.facet syntax errors

    (Dr Oleg Savrasov, Mikhail Khludnev)
  • SOLR-13229: Cleanup replicasMetTragicEvent after all types of exception
    (Tomás Fernández Löbbe)
  • SOLR-13234: Prometheus Metric Exporter not threadsafe. This changes the prometheus exporter to collect metrics from Solr on a fixed interval controlled by this tool and prevents concurrent collections. This change also improves performance slightly by using the cluster state instead of sending multiple HTTP requests to each node to lookup all the cores.
    (Danyal Prout, shalin)
  • SOLR-13244: Admin UI Nodes view fails and is empty when a node is temporarily down
    (janhoy)
  • SOLR-13253: IndexSchema.getResourceLoader was being used to load non-schema things, which can be a memory leak if "shareSchema" and other circumstances occur. Furthermore it's reference to SolrConfig was removed.

    (Jason Gerlowski, janhoy)
  • SOLR-13362: Add 'includeIndexFieldFlags' support to SolrJ LukeRequest
    (Jason Gerlowski)

    (Mark Miller, Fernandez-Lobbe, Mike Drob)
  • SOLR-13388: Fix FileExchangeRateProvider to be a public class, as it appears in schema.xml
    (Uwe Schindler)
  • SOLR-13393: Fixed ZkClientClusterStateProvider to prevent risk of leaking ZkStateReader/threads when processing concurrent requests during shutdown. This primarily affected tests, but may have also caused odd errors/delays when restart/shutting down solr nodes.
    (hossman)
  • SOLR-13408: Cannot start/stop DaemonStream repeatedly, other API improvements
    (Erick Erickson)

Release 8.0.0 [2019-03-14]

• Upgrade Notes   (18)
  • LUCENE-7996: The 'func' query parser now returns scores that are equal to 0 when a negative value is produced. This change is due to the fact that Lucene now requires scores to be positive.
    (Adrien Grand)
  • LUCENE-8267: Memory codecs have been removed from the codebase (MemoryPostings, MemoryDocValues). If you used postingsFormat="Memory" or docValuesFormat="Memory" then either remove it to use the default or experiment with one of the others.
    (Dawid Weiss)
  • SOLR-11702: Due to the introduction of LIR redesign since Solr 7.3 (SOLR-11702) and the removing of old LIR implementation in Solr 8. Rolling updates are not possible unless all nodes must be on Solr 7.3 or higher. If not updates can be lost.
  • SOLR-11774: In 'langid' contrib, the LanguageIdentifierUpdateProcessor base class changed some method signatures. If you have a custom language identifier implementation you will need to adapt your code.
  • SOLR-11882: SolrMetric registries retained references to SolrCores when closed. A change of SolrMetricMAnager.registerGauge and SolrMetricProducer.initializeMetrics method signatures was required to fix it. Third party components that use this API need to be updated.
    (Eros Taborelli, Erick Erickson, ab)
  • SOLR-12586: The date format patterns used by ParseDateFieldUpdateProcessorFactory (present in "schemaless mode") are now interpreted by Java 8's java.time.DateTimeFormatter instead of Joda Time. The pattern language is very similar but not the same. Typically, simply update the pattern by changing an uppercase 'Z' to lowercase 'z' and that's it. For the current recommended set of patterns in schemaless mode, see "Schemaless Mode" in the ref guide, or simply examine the default configSet. Also note that the set of patterns (formats) here have expanded from before to subsume those patterns previously handled by the "extract" contrib (Solr Cell / Tika).
    (David Smiley, Bar Rotstein)
  • SOLR-12593: The "extraction" contrib (Solr Cell) no longer does any date parsing, and thus no longer has the "date.formats" configuration. To ensure date strings are properly parsed, use ParseDateFieldUpdateProcessorFactory (an URP) commonly registered with the name "parse-date" in "schemaless mode".
    (David Smiley, Bar Rotstein)
  • SOLR-12605: UpdateShardHandler's updateOnlyClient is now a Http2SolrClient (previous HttpSolrClient). This new client does not support 'maxConnections','maxConnectionsPerHost' parameters.
  • SOLR-12633: When JSON data is sent to Solr with nested child documents split using the "split" parameter, the child docs will now be associated to their parents by the field/label string used in the JSON instead of anonymously. Most users probably won't notice the distinction since the label is lost any way unless special fields are in the schema. This choice used to be toggleable with an internal/expert "anonChildDocs" parameter flag which is now gone.
    (David Smiley)
  • SOLR-12640: HttpShardHandlerFactory's defaultClient is now a Http2SolrClient (previous HttpSolrClient). This new client does not support 'maxConnections','maxConnectionsPerHost' parameters. LBHttpSolrClient.Req and LBHttpSolrClient.Rsp are marked as deprecated, uses LBSolrClient.Req and LBSolrClient.Rsp instead.
  • SOLR-12643: Since Http2SolrClient does not support exposing connections related metrics. These metrics are no longer available 'QUERY.httpShardHandler.{availableConnections, leasedConnections, maxConnections, pendingConnections}', 'UPDATE.updateShardHandler.{availableConnections, leasedConnections, maxConnections, pendingConnections}'
  • SOLR-12754: The UnifiedHighlighter hl.weightMatches now defaults to true. If there are unforseen highlight problems, this may be the culprit.
  • SOLR-13025: If you explicitly use BM25SimilarityFactory in your schema, the absolute scoring will be lower due to SOLR-13025. But ordering of documents will not change in the normal case. Use LegacyBM25SimilarityFactory if you need to force the old 6.x/7.x scoring. Note that if you have not specified any similarity in schema or use the default SchemaSimilarityFactory, then LegacyBM25Similarity is automatically selected for 'luceneMatchVersion' < 8.0.0. See also explanation in Reference Guide chapter "Other Schema Elements".
  • SOLR-13248: The default replica placement strategy used in Solr has been reverted to the 'legacy' policy used by Solr 7.4 and previous versions. This is due to multiple bugs in the autoscaling based replica placement strategy that was made default in Solr 7.5 which causes multiple replicas of the same shard to be placed on the same node in addition to the maxShardsPerNode and createNodeSet parameters being ignored. Although the default has changed, autoscaling will continue to be used if a cluster policy or preference is specified or a collection level policy is in use. The default replica placement strategy can be changed to use autoscaling again by setting a cluster property: curl -X POST -H 'Content-type:application/json' --data-binary ' { "set-obj-property": { "defaults" : { "cluster": { "useLegacyReplicaAssignment":false } } } }' http://$SOLR_HOST:$SOLR_PORT/api/cluster
  • SOLR-5211: Deleting (or updating) documents by their uniqueKey is now scoped to only consider root documents, not child/nested documents. Thus a delete-by-id won't work on a child doc (no-op), and an attempt to update a child doc by providing a new doc with the same ID would add a new doc (probably erroneous). Both these actions were and still are problematic. In-place-updates are safe though. If you want to delete certain child documents and if you know they don't themselves have nested children then you must do so with a delete-by-query technique.
  • Solr nodes can now listen and serve HTTP/2 requests. Most of internal requests
    (sent by UpdateShardHandler, HttpShardHandler)
  • ALPN is not supported in Java 8 or lower version therefore when a node started in Java 8 or a lower version with SSL enabled, it will send and can only be able to handle HTTP/1.1 requests. In case of using SSL Java 9 or latter versions are recommended.
  • Custom AuthenticationPlugin must provide its own setup for Http2SolrClient through implementing HttpClientBuilderPlugin.setup, if not internal requests can't be authenticated.
• Added   (14)
  • SOLR-11126: New Node-level health check handler at /admin/info/healthcheck and /node/health paths that checks if the node is live, connected to zookeeper and not shutdown.
    (Anshum Gupta, Amrit Sarkar, shalin)
  • SOLR-12591: Expand the set of recognized date format patterns of schemaless mode to subsume those handled by the "extract" contrib (Solr Cell / Tika). This is primarily a change in configuration of the default configSet for more patterns, but also included enabling "lenient" parsing in ParseDateFieldUpdateProcessorFactory. The default locale was changed from ROOT to en_US since well-known patterns assume this locale.
    (David Smiley, Bar Rotstein)
  • SOLR-12593: The default configSet now includes an "ignored_*" dynamic field.
    (David Smiley)
  • SOLR-12639: Umbrella JIRA for adding support HTTP/2
    (Cao Manh Dat)
  • SOLR-12730: Implement staggered SPLITSHARD requests in IndexSizeTrigger.
    (ab)
  • SOLR-12768: Improved nested document support, and enabled in the default schema with the presence of _nest_path_. When this field is present, certain things happen automatically. An internal URP is automatically used to populate it. The [child] (doc transformer) will return a hierarchy with relationships; no params needed. The relationship path is indexed for use in queries (can be disabled if not needed). Also, child documents needn't provide a uniqueKey value as Solr will supply one automatically by concatenating a path to that of the parent document's key. [SOLR-13129](https://issues.apache.org/jira/browse/SOLR-13129)
    (David Smiley, Moshe Bla)
  • SOLR-12791: Add Metrics reporting for AuthenticationPlugin
    (janhoy)
  • SOLR-12799: Allow Authentication Plugins to intercept internode requests on a per-request basis. The BasicAuth plugin now supports a new parameter 'forwardCredentials', and when set to 'true', user's BasicAuth credentials will be used instead of PKI for client initiated internode requests.
    (janhoy, noble)
  • SOLR-12879: MinHash query parser that builds queries providing a measure of Jaccard similarity
    (Andy Hind, Tommaso Teofili)
  • SOLR-13104: Add natural and repeat Stream Evaluators
    (Joel Bernstein)
  • SOLR-13134: Allow the knnRegress Stream Evaluator to more easily perform bivariate regression.

  • SOLR-13147: Add movingMAD Stream Evaluator
    (Joel Bernstein)
  • SOLR-13155: Add command-line option for testing autoscaling configurations.
    (ab)
  • SOLR-13241: Add 'autoscaling' tool support to solr.cmd
    (Jason Gerlowski)
• Changed   (6)
  • SOLR-12725: ParseDateFieldUpdateProcessorFactory should reuse ParsePosition.
    (ab)
  • SOLR-12888: The NestedUpdateProcessor (which populates internal fields for nested child docs) is now auto-registered to run immediately prior to RunUpdateProcessor. If the schema has no _nest_*_ fields then it's a no-op. RunUpdateProcessorFactory looks up a special/internal URP chain "_preRun_" which is implicitly defined but could be defined by an app for customization if desired.
    (David Smiley)
  • SOLR-13025: Due to LUCENE-8563, the BM25Similarity formula no longer includes the (k1+1) factor in the numerator This gives a lower absolute score but doesn't affect ordering, as this is a constant factor which is the same for every document. Use LegacyBM25SimilarityFactory if you need the old 6.x/7.x scoring. See also upgrade notes [LUCENE-8563](https://issues.apache.org/jira/browse/LUCENE-8563)
    (janhoy)
  • SOLR-13130: during the ResponseBuilder.STAGE_GET_FIELDS directly copy string bytes and avoid creating String Objects
    (noble)
  • SOLR-5211: If _root_ is defined in the schema, it is now always populated automatically. This allows documents with children to be updated with a document that does not have children, whereas before it would break block-join queries. If you don't use nested documents then _root_ can be removed from the schema.
    (Dr Oleg Savrasov, Moshe Bla, David Smiley, Mikhail Khludnev)
  • SOLR-6117: The response format has changed slightly for ReplicationHandler error-cases. All errors now have a non-200 'status' field, a 'message' field giving more details on the error, and an optional 'exception' field.
    (Shalin Mangar, Jason Gerlowski)
• Fixed   (5)
  • SOLR-11774: langid.map.individual now works together with langid.map.keepOrig. Also the detectLanguage() API is changed to accept a Reader allowing for more memory efficient implementations
    (janhoy)
  • SOLR-13058: Fix block that was synchronizing on the wrong collection in OverseerTaskProcessor
    (Gus Heck)
  • SOLR-13126: Query boosts were not being combined correctly for documents where not all boost queries matched
    (Alan Woodward, Mikhail Khludnev)
  • SOLR-13248: Autoscaling based replica placement is broken out of the box. Solr 7.5 enabled autoscaling based replica placement by default but in the absence of default cluster policies, autoscaling can place more than 1 replica of the same shard on the same node. Also, the maxShardsPerNode and createNodeSet was not respected. Due to these reasons, this issue reverts the default replica placement policy to the 'legacy' assignment policy that was the default until Solr 7.4.
    (Gus Heck, Andrzej Bialecki, Bram Van Dam, shalin)
  • SOLR-13255: ClasscastException when URPs try to read a String field which returns a ByteArrayUTF8CHarSequence . This is a regression in release 7.7 (noble) *SOLR-13299: Fix Windows startup script to disable HTTP/2 if TLS is enabled on Java 8. [SOLR-13299](https://issues.apache.org/jira/browse/SOLR-13299)

    (David Smiley)
  • SOLR-12586: Upgrade ParseDateFieldUpdateProcessorFactory (present in "schemaless mode") to use Java 8's java.time.DateTimeFormatter instead of Joda time (see upgrade notes). "Lenient" is enabled. Removed Joda Time dependency.
    (David Smiley, Bar Rotstein)

    (Charles Sanders, David Smiley)
  • SOLR-9515: Hadoop dependencies have been upgraded to Hadoop 3.2.0 from 2.7.2.
    (Mark Miller, Kevin Risden)

Release 7.7.3 [2020-04-28]

• Fixed   (10)
  • SOLR-12291: prematurely reporting not yet finished async Collections API call as completed when collection's replicas are colocated at least at one node
    (Varun Thacker, Mikhail Khludnev)
  • SOLR-13158: DataImportHandler: Added enable.dih.dataConfigParam system property to toggle whether the dataConfig param is permitted.
    (David Smiley, janhoy, Tomás Fernández Löbbe)
  • SOLR-13472: Forwarded requests should skip authorization on receiving nodes
    (Ishan Chattopadhyaya)
  • SOLR-13718: SPLITSHARD (async) with failures in underlying sub-operations can result in data loss
    (Ishan Chattopadhyaya)
  • SOLR-13779: Use the safe fork of simple-xml for clustering contrib.
    (Dawid Weiss, Sachin Pattan)
  • SOLR-13793: HttpSolrCall now maintains internal request count (_forwardedCount) for remote queries and limits them to the number of replicas. This avoids making too many cascading calls to remote servers, which, if not restricted, can bring down nodes containing the said collection
    (Kesharee Nandan Vishwakarma, Ishan Chattopadhyaya)
  • SOLR-13828: Improve ExecutePlanAction error handling.
  • SOLR-13971: Velocity response writer's resource loading now possible only through startup parameters. Also, removed velocity response writer from _default configset.
    (Ishan Chattopadhyaya, Sachin Pattan)
  • SOLR-14025: VelocityResponseWriter has been hardened - only trusted configsets can render configset provided templates and rendering templates from request parameters has been removed.
  • SOLR-14259: Back port javabin performance regression fixes from SOLR-14013 [SOLR-14013](https://issues.apache.org/jira/browse/SOLR-14013)
    (noble)

Release 7.7.2 [2019-06-04]

• Upgrade Notes   (2)
  • SOLR-12708: When requesting the status of an async request via REQUESTSTATUS collections API, the response will include the list of internal async requests (if any) in the "success" or "failed" keys (in addition to them being included outside those keys for backwards compatibility). See SOLR-12708 for more details
  • SOLR-13234: The Prometheus Metric Exporter now collects metrics from Solr at a fixed schedule that is controlled by the exporter itself. The default interval is 60s but it can be changed by specifying the --scrape-interval command line parameter to the tool. The collected metrics are cached and returned for any requests coming in before the next scheduled collection. This can impact the freshness of the metrics if prometheus is configured to query the tool more frequently.
• Fixed   (25)
  • SOLR-11876: In-place update fails when resolving from Tlog if schema has a required field
    (Justin Deoliveira, janhoy, Ishan Chattopadhyaya)

  • SOLR-13229: Cleanup replicasMetTragicEvent after all types of exception
    (Tomás Fernández Löbbe)
  • SOLR-13234: Prometheus Metric Exporter not threadsafe. This changes the prometheus exporter to collect metrics from Solr on a fixed interval controlled by this tool and prevents concurrent collections. This change also improves performance slightly by using the cluster state instead of sending multiple HTTP requests to each node to lookup all the cores.
    (Danyal Prout, shalin)
  • SOLR-13252: Fix an NPE when setting a "policy" property for an existing collection

Release 7.6.0 [2018-12-14]

• Upgrade Notes   (4)
  • SOLR-12739: Autoscaling policy framework is now used as the default strategy to select the nodes on which new replicas or replicas of new collections are created. Previously, the maxShardsPerNode parameter was not allowed on collections when autoscaling policy was configured. Also if an autoscaling policy was configured then the default was to set an unlimited maxShardsPerNode automatically. Now the maxShardsPerNode parameter is always allowed during collection creation and maxShardsPerNode should be set correctly (if required) regardless of whether autoscaling policies are in effect or not. The default value of maxShardsPerNode continues to be 1 as before. It can be set to -1 during collection creation to fall back to the old behavior of unlimited maxShardsPerNode when using autoscaling policy.
  • SOLR-12767: The min_rf parameter is no longer needed, Solr will always return the achieved replication factor
    (rf)
  • SOLR-12827: The cluster wide defaults structure has changed from {collectionDefaults: {nrtReplicas : 2}} to {defaults : {collection : {nrtReplicas : 2}}}. The old format continues to be supported and can be read from ZK as well as written using the V2 set-obj-property syntax but it is deprecated and will be removed in Solr 9. We recommend that users change their API calls to use the new format going forward.
  • SOLR-12861: Added a Solr factory for ByteBuffersDirectory, which will replace deprecated RAMDirectory in Solr 9.0.
• Added   (25)
  • SOLR-11522: /autoscaling/suggestions now include rebalance options as well even if there are no violations
    (noble)
  • SOLR-11572: Add recip Stream Evaluator to support reciprocal transformations
    (Joel Bernstein)
  • SOLR-11907: Add convexHull and associated geometric Stream Evaluators.
    (Joel Bernstein)
  • SOLR-11997: Suggestions API/UI should show an entry where a violation could not be resolved
    (noble)
  • SOLR-12754: The UnifiedHighlighter has a new hl.weightMatches param defaulting to false (will be true in 8.0). It's the highest query accuracy mode, and furthermore phrase queries are highlighted as one.
    (David Smiley)
  • SOLR-12780: Add support for Leaky ReLU and TanH activations in contrib/ltr NeuralNetworkModel class.
    (Kamuela Lau, Christine Poerschke)
  • SOLR-12795: Introduce 'rows' and 'offset' parameter in FacetStream
    (Joel Bernstein, Amrit Sarkar, Varun Thacker)
  • SOLR-12811: Add enclosingDisk and associated geometric Stream Evaluators.
    (Joel Bernstein)
  • SOLR-12815: Implement maxOps limit for IndexSizeTrigger.
    (ab)
  • SOLR-12822: /autoscaling/suggestions to include suggestion to add-replica for lost replicas
    (noble)
  • SOLR-12828: Add oscillate Stream Evaluator to support sine wave analysis.
    (Joel Bernstein)
  • SOLR-12829: Add plist (parallel list) Streaming Expression
    (Joel Bernstein)
  • SOLR-12840: Add pairSort Stream Evaluator
    (Joel Bernstein)
  • SOLR-12843: Implement a MultiContentWriter in SolrJ to post multiple files/payload at once
    (noble)
  • SOLR-12846: Added support for "host" variable in autoscaling policy rules
    (noble)
  • SOLR-12862: Add log10 Stream Evaluator and allow the pow Stream Evaluator to accept a vector of exponents
    (Joel Bernstein)
  • SOLR-12936: Allow percentiles Stream Evaluator to accept an array of percentiles to calculate
    (Joel bernstein)
  • SOLR-12938: Cluster Status returns results for aliases, instead of throwing exceptions
    (Gus Heck)
  • SOLR-12942: Add an option in IndexSizeTrigger to select the split shard method.
    (ab)
  • SOLR-12962: Added a new 'uninvertible' option for fields and fieldtypes. This defaults to 'true' for backcompat allowing a FieldCache to be built for indexed fields as needed, but users are encouraged to set this to false (using docValues as needed) to reduce the risk of large fluxuations in heap size due to unexpected attempts to sort/facet/function on non-docValue fields.
    (hossman)
  • SOLR-12971: Add pivot Stream Evaluator to pivot facet co-occurrence counts into a matrix
    (Joel Bernstein)
  • SOLR-12975: Add ltrim and rtrim Stream Evaluators
    (Joel Bernstein)
  • SOLR-5004: Splitshard collections API now supports splitting into more than 2 sub-shards directly i.e. by providing a numSubShards parameter
    (Christine Poerschke, Anshum Gupta)
  • SOLR-6280: {!collapse}: if you attempt to use CollapseQParser on a field that is multi-valued, you will now get an error. Previously, the collapsing behavior was unreliable and undefined despite no explicit error.
    (Munendra S N, David Smiley)
  • SOLR-9317: ADDREPLICA command should be able to add more than one replica to a collection,shard at a time. The API now supports 'nrtReplicas', 'tlogReplicas', 'pullReplicas' parameters as well 'createNodeSet' parameter. As part of this change, the CREATESHARD API now delegates placing replicas entirely to the ADDREPLICA command and uses the new parameters to add all the replicas in one API call.
    (shalin)
• Changed   (11)
  • LUCENE-8557: Some internal LeafReader.getFieldInfos implementations were being re-computed on-demand instead of once up front leading to some slowdowns in places like JSON Facets and field collapsing.
    (Tim Underwood, David Smiley)
  • SOLR-10981: Support for stream.url or stream.file pointing to gzipped data. It's detected by either a content encoding header or file extension.
    (Andrew Lundgren, David Smiley, Jan Høydahl)
  • SOLR-12699: Make contrib/ltr LTRScoringModel immutable and cache its hashCode.
    (Stanislav Livotov, Edward Ribeiro, Christine Poerschke)
  • SOLR-12739: Make autoscaling policy based replica placement the default strategy for placing replicas.
    (shalin)
  • SOLR-12767: Solr now always includes in the response of update requests the achieved replication factor
    (Tomás Fernández Löbbe)
  • SOLR-12782: UninvertingReader wrapping is now a bit more lightweight: Does not create FieldInfo for fields that can't be uninverted (saves mem) and can avoid wrapping the reader altogether if there's nothing to uninvert. IndexSchema.getUninversionMap refactored to getUninversionMapper and no longer merges FieldInfos.
    (David Smiley)
  • SOLR-12806: use autoscaling policies with strict=false to prioritize node allocation
    (noble)
  • SOLR-12880: Json Facets: Show the FacetProcessor class name instead of the FacetRequest in the JSON Facets debug-trace output
    (Tim Underwood)
  • SOLR-12882: Eliminate excessive lambda allocation in json facets FacetFieldProcessorByHashDV
    (Tim Underwood)
  • SOLR-12892: MapWriter to use CharSequence instead of String
    (noble)
  • SOLR-12964: Json Facets: use DocValuesIterator advanceExact() instead of advance() in FacetFieldProcessorByHashDV and UniqueSinglevaluedSlotAcc.
    (Tim Underwood)
• Fixed   (19)
  • SOLR-11836: FacetStream works with bucketSizeLimit of -1 which will fetch all the buckets.
    (Alfonso Muñoz-Pomer Fuentes, Amrit Sarkar, Varun Thacker)
  • SOLR-12023: Autoscaling policy engine shuffles replicas needlessly
    (noble)
  • SOLR-12243: Edismax missing phrase queries when phrases contain multiterm synonyms
    (Elizabeth Haubert, Alessandro Benedetti, Uwe Schindler, Steve Rowe)
  • SOLR-12648: Autoscaling framework based replica placement is not used unless a policy is specified or non-empty cluster policy exists.
    (shalin)
  • SOLR-12729: SplitShardCmd should lock the parent shard to prevent parallel splitting requests.
    (ab)
  • SOLR-12750: Migrate API should lock the collection instead of shard.
    (shalin)
  • SOLR-12767: When using min_rf, shard leader skipped bad replicas instead of marking them for recovery, this could create inconsistencies between replicas of the same shard. min_rf parameter is now deprecated, and even if provided replicas that don't ack an update from the leader will be marked for recovery.
    (Tomás Fernández Löbbe)
  • SOLR-12776: Setting of TMP in solr.cmd causes invisibility of Solr to JDK tools
    (Petr Bodnar, Erick Erickson)
  • SOLR-12803: Ensure ConcurrentUpdateSolrClient sends documents to correct collection
    (Jason Gerlowski)
  • SOLR-12814: Metrics history causing "HttpParser URI is too large >8192" when many collections
    (janhoy)
  • SOLR-12836: ZkController creates a cloud solr client with no connection or read timeouts. Now the http client created by the update shard handler is used instead.
    (shalin)
  • SOLR-12851: Improvements and fixes to let and select Streaming Expressions
    (Joel Bernstein)
  • SOLR-12868: Request forwarding for v2 API is broken
    (noble)
  • SOLR-12874: Java 9+ GC Logging filesize parameter should use a unit.
    (Tim Underwood, Uwe Schindler)

    (noble)
  • SOLR-7557: Fix parsing of child documents using queryAndStreamResponse
    (Marvin Bredal Lillehaug, Stian Østerhaug, janhoy)
• Other   (13)
  • SOLR-12423: Upgrade to Tika 1.19.1 when available
    (Tim Allison, Erick Erickson)

    (Mano Kovacs, Cassandra Targett)
  • SOLR-12600: Fix parameter names in Solr JSON documentation
    (Alexandre Rafalovitch)
  • SOLR-12746: Simplify the Ref Guide HTML structure and use semantic HTML tags where possible. Adds new template files for Asciidoctor HTML conversion. Building the HTML version now requires the Slim gem.
    (Cassandra Targett)
  • SOLR-12756: Refactor Assign and extract replica placement strategies out of it. Now, assignment is done with the help of a builder class instead of calling a method with large number of arguments. The number of special cases that had to be handled have been cut down as well.
    (shalin)
  • SOLR-12762: Fix javadoc for SolrCloudTestCase.clusterShape() method and add a method that validates only against Active slices
    (Anshum Gupta)
  • SOLR-12793: Move TestCloudJSONFacetJoinDomain and TestCloudJSONFacetSKG to the facet test package
    (Varun Thacker)
  • SOLR-12827: Migrate cluster wide defaults syntax in cluster properties to a nested structure. The structure has changed from {collectionDefaults: {nrtReplicas : 2}} to {defaults : {collection : {nrtReplicas : 2}}}.
    (ab, shalin)
  • SOLR-12835: Document statistics exposed by the Query Result Cache when maxRamMB is configured.

Release 7.5.0 [2018-09-24]

• Upgrade Notes   (7)
  • LUCENE-7976: TieredMergePolicy now respects maxSegmentSizeMB by default when executing findForcedMerges (optimize) and findForcedDeletesMerges
    (expungeDeletes, Erick Erickson)
  • SOLR-11694: Extremely outdated UIMA contrib module has been removed
    (Alexandre Rafalovitch)
  • SOLR-12008: The configuration file for log4j2.xml is now in ../server/resources/log4j2.xml. All other copies have been removed. WINDOWS USERS: This JIRA corrects a bug in the start scripts that put example logs under ...\server, solr.log is now under ...\example.
    (Erick Erickson)
  • SOLR-12350: The data-driven schema no longer returns the *_str field-copy of text fields by default. The *_str field is still created and can be used for e.g. sorting, but to retrieve it you now need to explicitly list it in "fl" SOLR-12350
  • SOLR-12395: SignificantTermsQParserPlugin's name is now 'significantTerms' and its old name 'sigificantTerms' is deprecated.
  • SOLR-12398: The heatmap facet response structure, when returned in JSON, changed from an even/odd name/value array to an object style. Although the object style makes more sense, this was an overlooked back-compat break; sorry.
  • The data-driven schema no longer returns the *_str field-copy of text fields by default. The *_str field is still created and can be used for e.g. sorting, but to retrieve it you now need to explicitly list it in "fl"
    (SOLR-12350)
• Added   (42)
  • SOLR-11578: Solr 7 Admin UI (Cloud > Graph) should reflect the Replica type to give a more accurate representation of the cluster.
    (Rhoit Singh, Erick Erickson)
  • SOLR-11861: When creating a configSet via the API, the "baseConfigSet" parameter now defaults to "_default".
    (Amrit Sarkar, David Smiley)
  • SOLR-11863: Add knnRegress Stream Evaluator to support nearest neighbor regression
    (Joel Bernstein)
  • SOLR-11865: The QueryElevationComponent now has a useConfiguredElevatedOrder setting. When multiple docs are elevated, this specifies whether their relative order should be the order in the configuration file or if not then should they be subject to whatever the sort criteria is. Additionally, QEC was extensively refactored to be more extensible.
    (Bruno Roustant, David Smiley)
  • SOLR-11943: Add machine learning functions for location data
    (Joel Bernstein)
  • SOLR-11985: Support percentage values in replica attribute in autoscaling policy
    (noble)
  • SOLR-11986: Allow percentage in freedisk attribute in autoscaling policy rules
    (noble)
  • SOLR-11990: Make it possible to co-locate replicas of multiple collections together in a node. A collection may be co-located with another collection during collection creation time by specifying a 'withCollection' parameter. It can also be co-located afterwards by using the modify collection API. The co-location guarantee is enforced regardless of future cluster operations whether they are invoked manually via the Collection API or by the Autoscaling framework.
    (noble, shalin)
  • SOLR-12357: Time Routed Aliases now have a preemptiveCreateMath option to preemptively and asynchronously create the next collection in advance as new data gets within this time window of the end.
    (Gus Heck, David Smiley)
  • SOLR-12361: Allow nested child documents to be in field values of a SolrInputDocument as an alternative to add/get ChildDocuments off to the side. The latter is now referred to as "anonymous" child documents as opposed to "labelled" (by the field name). Anonymous child docs might be deprecated in the future. This is an internal change that should work for javabin/SolrJ; separate issues will address XML & JSON formats populating nested docs in this way. AddUpdateCommand and it's relationship with DirectUpdateHandler2 was reworked substantially.
    (Moshe Bla, David Smiley)
  • SOLR-12362: Uploading docs in JSON now supports child documents as field values, thus providing a label to the relationship instead of the current "anonymous" relationship. Use of this experimental feature sometimes requires a anonChildDocs=false parameter until Solr 8 due to syntax ambiguities.
    (Moshe Bla, David Smiley)
  • SOLR-12398: The JSON Facet API now supports type=heatmap facets, just as classic faceting does.
    (David Smiley)
  • SOLR-12402: Factor out SolrDefaultStreamFactory class.
    (Christine Poerschke)
  • SOLR-12441: (EXPERIMENTAL) New NestedUpdateProcessorFactory (URP) to populate special fields _nest_parent_ and _nest_path_ of nested (child) documents. It will generate a uniqueKey of nested docs if they were blank too.
    (Moshe Bla, David Smiley)
  • SOLR-12474: Add an UpdateRequest Object that implements RequestWriter.ContentWriter
    (noble)
  • SOLR-12485: Uploading docs in XML now supports child documents as field values, thus providing a label to the relationship instead of the current "anonymous" relationship.
    (Moshe Bla, David Smiley)
  • SOLR-12495: An #EQUAL function for replica in autoscaling policy to equally distribute replicas
    (noble)
  • SOLR-12506: Add SolrJ support for the modify collection API.
    (shalin)
  • SOLR-12507: Modify collection API should support un-setting properties.
    (shalin)
  • SOLR-12511: Support non integer values for replica in autoscaling policy
    (noble)
  • SOLR-12517: Support range values for replica in autoscaling policy
    (noble)
  • SOLR-12519: The [child] transformer now returns a nested child doc structure (attached as fields if provided this way) provided the schema has the _nest_path_ field. This is part of a broader enhancement of nested docs.
    (Moshe Bla, David Smiley)
  • SOLR-12522: Support a runtime function `#ALL` for 'replica' in autoscaling policies
    (noble)
  • SOLR-12530: Ability to disable configset upload via -Dconfigset.upload.enabled=false startup parameter
    (Ishan Chattopadhyaya)
  • SOLR-12536: autoscaling policy support to equally distribute replicas on the basis of arbitrary properties
    (noble)
  • SOLR-12567: JSON Facet "functions" now support an extended "type:func" syntax, similar to other types of facets. This also allows additional local params to be specified for if the aggregation function can take advantage of them.
    (hossman)
  • SOLR-12581: the JSON Facet 'relatedness()' aggregate function now supports a 'min_popularity' option using the extended type:func syntax
    (hossman)
  • SOLR-12592: support #EQUAL function, range operator, decimal and percentage in cores in autoscaling policies
    (noble)
  • SOLR-12612: Cluster properties restriction of known keys only is relaxed, and now unknown properties starting with "ext." will be allowed. This allows custom to plugins set their own cluster properties.
    (Jeffery Yuan, Tomás Fernández Löbbe)
  • SOLR-12629: The predict evaluator should work with the polyfit function
    (Joel Bernstein)
  • SOLR-12634: Add gaussfit Stream Evaluator
    (Joel Bernstein)
  • SOLR-12655: Add Korean morphological analyzer ("nori") to default distribution. This also adds examples for configuration in Solr's schema.
    (Uwe Schindler)
  • SOLR-12660: Add outliers Stream Evaluator to support outlier detection with probability distributions
    (Joel Bernstein)
  • SOLR-12671: Add robust flag to knnRegress Stream Evaluator
    (Joel Bernstein)
  • SOLR-12687: Add functions to cache data structures and mathematical models
    (Joel Bernstein)
  • SOLR-12702: Add zscores Stream Evaluator
    (Joel Bernstein)
  • SOLR-12715: NodeAddedTrigger should support adding replicas to new nodes by setting preferredOperation=addreplica.
    (shalin)
  • SOLR-12716: NodeLostTrigger should support deleting replicas from lost nodes by setting preferredOperation=deletenode.
    (shalin)
  • SOLR-12722: The [child] transformer now takes an 'fl' param to specify which fields to return. It will evaluate doc transformers if present. In 7.5 a missing 'fl' defaults to the current behavior of all fields, but in 8.0 defaults to the top/request "fl".
    (Moshe Bla, David Smiley)
  • SOLR-7767: "ZK Status" sub menu under "Cloud" tab to see status of zookeeper ensemble
    (janhoy)
  • SOLR-8207: Add "Nodes" view to the Admin UI "Cloud" tab, listing nodes and key metrics
    (janhoy)
  • SOLR-9418: Added a new (experimental) PhrasesIdentificationComponent for identifying potential phrases in query input based on overlapping shingles in the index.
    (Akash Mehta, Trey Grainger, hossman)
• Changed   (12)
  • SOLR-10697: HttpShardHandler now uses a default of 100k as maxConnections (10k previously) and default maxConnectionsPerHost as 100k (20 previously). They are now consisent with the UpdateShardHandler defaults.
    (Varun Thacker)
  • SOLR-11598: The export handler does not limit users to 4 sort fields and is now unlimited. However the speed at which we can export is directly proportional to the number of sort fields specified. This change also allows streaming expressions to group by on more than 4 fields.
    (Aroop Ganguly, Amrit Sarkar, Varun Thacker)
  • SOLR-11654: Time Routed Alias will now route documents to the ideal shard of a collection, thus avoiding a hop. Usually documents were already routed well but not always.
    (Gus Heck, David Smiley)
  • SOLR-11881: Retry update requests sent by leaders to it's followers
    (Varun Thacker, Mark Miller, Tomás Fernández Löbbe)
  • SOLR-12305: When a replica is applying updates, some kind of updates can skip buffering for faster recovery.
    (Cao Manh Dat)
  • SOLR-12350: Do not use docValues as stored for _str (copy)fields in _default configset
    (janhoy)
  • SOLR-12455: Refactor JSON serialization code into SolrJ package
    (noble)
  • SOLR-12509: Improve SplitShardCmd performance and reliability. A new method of splitting has been introduced (splitMethod=link) which uses hard-linking of index files when possible, resulting in significant speedups and reduced CPU / IO load on shard leader.
    (ab)
  • SOLR-12572: While exporting documents using the export writer, if a field is specified as a sort parameter and also in the fl (field list) parameter, we save on one doc-value lookup. This can bring performance improvements of 15% and upwards depending on how many fields are in common.
    (Amrit Sarkar, Varun Thacker)
  • SOLR-12616: Optimize Export writer upto 4 sort fields to get better performance. This was removed in SOLR-11598 but brought back in the same version [SOLR-11598](https://issues.apache.org/jira/browse/SOLR-11598)
    (Amrit Sarkar, Varun Thacker)
  • SOLR-12723: Reduce object creation in HashBasedRouter.

  • SOLR-12607: Fixed two separate bugs in shard splits which can cause data loss. The first case is when using TLOG replicas only, the updates forwarded from parent shard leader to the sub-shard leader are written only in tlog and not the index. If this happens after the buffered updates have been replayed then the updates can never be executed even though they remain the transaction log. The second case is when synchronously forwarding updates to sub-shard leader fails and the underlying errors are not propagated to the client.

Release 7.4.0 [2018-06-27]

• Upgrade Notes   (3)
  • SOLR-11453: Configuring slowQueryThresholdMillis now logs slow requests to a separate file - solr_slow_requests.log. Previously they would get logged in the solr.log file.
  • SOLR-11673: Slave doesn't commit empty index when completely new index is detected on master during replication. To return the previous behavior pass false to skipCommitOnLeaderVersionZero in slave section of replication handler configuration, or pass it to the fetchindex command.
  • SOLR-7887: Solr now uses Log4J 2.11 . The log4j configuration is now in log4j2.xml rather than log4j.properties files. This is a server side change only and clients using SolrJ won't need any changes. Clients can still use any logging implementation which is compatible with SLF4J. We now let log4j2 handle rotation of solr logs at startup, and bin/solr start scripts will no longer attempt this nor move existing console or GC logs into logs/archived either SOLR-12144 [SOLR-12144](https://issues.apache.org/jira/browse/SOLR-12144)
• Added   (35)

    (Rupa Shankar, Anshum Gupta)
  • SOLR-11336: DocBasedVersionConstraintsProcessorFactory is more extensible and now supports a list of versioned fields. (versionField config may now be a comma-delimited list).
    (Michael Braun, David Smiley)
  • SOLR-11453: Configuring slowQueryThresholdMillis logs slow requests to a separate file - solr_slow_requests.log.
    (Shawn Heisey, Remko Popma, Varun Thacker)
  • SOLR-11670: Implement a periodic house-keeping task. This uses a scheduled autoscaling trigger and currently performs cleanup of old inactive shards.
    (ab, shalin)
  • SOLR-11734: Add ones and zeros Stream Evaluators
    (Joel Bernstein)
  • SOLR-11779: Basic long-term collection of aggregated metrics. Historical data is maintained as multi-resolution time series using round-robin databases in the '.system' collection. New /admin/metrics/history API allows retrieval of this data in numeric or graph formats. [SOLR-12438](https://issues.apache.org/jira/browse/SOLR-12438)
    (ab)

    (Amrit Sarkar, noble)
  • SOLR-12036: Factor out DefaultStreamFactory solrj class.
    (Christine Poerschke)

    (David Smiley)
  • SOLR-12378: Support missing versionField on indexed docs in DocBasedVersionConstraintsURP.
    (Oliver Bates, Michael Braun, Mark Miller)
  • SOLR-12387: cluster-wide defaults for numShards, nrtReplicas, tlogReplicas, pullReplicas
    (noble)
  • SOLR-12388: Enable a strict ZooKeeper-connected search request mode, in which search requests will fail when the coordinating node can't communicate with ZooKeeper, by setting the "shards.tolerant" param to "requireZkConnected".
    (Steve Rowe)
  • SOLR-12389: support deeply nested json objects in clusterprops.json
    (noble)

    (Dmitry Tikhonov, Mikhail Khludnev, yonik)
• Changed   (13)
  • SOLR-11731: LatLonPointSpatialField can now decode points from docValues when stored=false docValues=true, albeit with maximum precision of 1.37cm
    (Karthik Ramachandran, David Smiley)
  • SOLR-11880: Avoid creating new exceptions for every request made to MDCAwareThreadPoolExecutor by distributed search and update operations.
    (Varun Thacker, shalin)
  • SOLR-11891: DocStreamer now respects the ReturnFields when populating a SolrDocument, reducing the number of unneccessary fields a ResponseWriter will see if documentCache is used
    (wei wang, hossman)
  • SOLR-11920: IndexFetcher now fetches only those files (from master/leader) that are different. This differential fetching now speeds up recovery times when full index replication is needed, but only a few segments diverge.
    (Ishan Chattopadhyaya, Shaun Sabo, John Gallagher)
  • SOLR-12198: Stream Evaluators should not copy matrices needlessly
    (Joel Bernstein)
  • SOLR-12233: QParserPlugin's built-in static registry now holds actual QParserPlugin instances instead of class references. This is consistent with other plugin registries and allows a SolrCore to load faster.
    (Jeff Miller, David Smiley)
  • SOLR-12312: Replication IndexFetcher should cap its internal buffer size when the file being transferred is small.
    (Jeff Miller, David Smiley)
  • SOLR-12333: Removed redundant lines for handling lists in JSON reponse writers.
    (David Smiley, Mikhail Khludnev)
  • SOLR-12337: Remove the obsolete QueryWrapperFilter intermediate wrapper, which also removed some needless uses of SolrConstantScoreQuery as well. QWF since v5.4.0 sometimes needlessly internally executed and cached the query. Affects ExpandComponent, ChildDocTransformer, CurrencyFieldType, TermsQParser.
    (David Smiley)
  • SOLR-12338: Replay buffering tlog in parallel.
    (Cao Manh Dat, David Smiley)
  • SOLR-12366: A slow "live docs" implementation was being used instead of a bitset. Affects classic faceting enum method, JSON Facets enum method, UnInvertedField faceting, GraphTermsQParser, JoinQParser.
    (David Smiley)
  • SOLR-12375: Optimize Lucene ScoreMode use: A non-cached filter query could be told incorrectly that scores were needed. The /export (ExportQParserPlugin) would declare incorrectly that scores are needed. Expanded docs (expand component) could be told incorrectly that scores are needed.
    (David Smiley)
  • SOLR-9922: Write buffering updates to another tlog.
    (Cao Manh Dat)
• Fixed   (56)
  • SOLR-10169: PeerSync will hit an NPE on no response errors when looking for fingerprint.
    (Erick Erickson)
  • SOLR-10513: ConjunctionSolrSpellChecker did not work with LuceneLevenshteinDistance
    (Amrit Sarkar, James Dyer)
  • SOLR-10734: AtomicUpdateRequestProcessor can cause wrong/old values to be set under concurrent updates for the same document. Multithreaded test for AtomicUpdateRequestProcessor was also beefed up and fixed.
    (Ishan Chattopadhyaya, Noble Paul, Amrit Sarkar, shalin)
  • SOLR-11551: Standardize CoreAdmin API success/failure status codes
    (Jason Gerlowski, Steve Rowe)
  • SOLR-11673: By default slave doesn't commit empty index when completely new index appears on master. See Upgrade Notes to find a way to get back to the previous behavior.
    (Mikhail Khludnev)
  • SOLR-11833: Allow searchRate trigger to delete replicas. Improve configurability of the trigger by specifying upper / lower thresholds and respective actions
    (ab)
  • SOLR-11840: Fix bin/solr help-text inconsistencies
    (Jason Gerlowski)
  • SOLR-11882: SolrMetric registries retained references to SolrCores when closed. A change of SolrMetricMAnager.registerGauge and SolrMetricProducer.initializeMetrics method signatures was required to fix it. Third party components may continue to use the old API but should be updated to avoid this bug
    (Eros Taborelli, Erick Erickson, ab)
  • SOLR-11929: UpdateLog metrics are not initialized on core reload.
    (ab, Steve Rowe)
  • SOLR-12035: ExtendedDismaxQParser fails to include charfilters in nostopanalyzer

    (Cao Manh Dat)
  • SOLR-12253: Remove optimize button from the core admin page
    (Erick Erickson)
  • SOLR-12258: A V2 request referencing a collection or alias may fail to resolve it if it was just recently created. Now we sync with ZooKeeper and try one more time. V1 partially did this but only for aliases; now it does both.
    (David Smiley)
  • SOLR-12261: If you attempt to delete a collection immediately after deleting an alias it used to be a part of, you may get an error that's it's a member of that alias. This check now ensures the alias state is sync()'ed with ZK first.
    (David Smiley)
  • SOLR-12271: Fixed bug in how Analytics component reads negative values from float and double fields.
    (Houston Putman)

    (Mikhail Khludnev)
  • SOLR-12308: LISTALIASES is now assured to return an up-to-date response. Also, the test utility MiniSolrCloudCluster.deleteAllCollections will now first delete aliases since a collection cannot be deleted if an alias refers to it.
    (David Smiley)
  • SOLR-12314: Use http timeout's defined in solr.xml for creating ConcurrentUpdateSolrClient during indexing requests between leader and replica

  • SOLR-12450: Don't allow referal to external resources in various config files (CVE-2018-8026).
    (Yuyang Xiao, Uwe Schindler)
  • SOLR-12481: update.autoCreateFields must be set via Config API command 'set-user-property', but 'bin/solr create' tells users to use the default action 'set-property', which fails because the property is not editable.
    (Steve Rowe)
  • SOLR-3567: Spellcheck custom parameters not being passed through due to wrong prefix creation.
    (Josh Lucas, shalin)

Release 7.3.0 [2018-04-04]

• Upgrade Notes   (10)
  • LUCENE-8161: If you are using the spatial JTS library with Solr, you must upgrade to 1.15.0. This new version of JTS is now dual-licensed to include a BSD style license.
  • SOLR-11624: Collections created without specifying a configset name use a copy of the _default configset since 7.0. Before 7.3, the copied over configset was named the same as the collection name, but 7.3 onwards it will be named with an additional ".AUTOCREATED" suffix.
  • SOLR-11702: The old Leader-In-Recovery implementation (SOLR-5495) is now deprecated and replaced. Solr will support rolling upgrades from old 7.x versions of Solr to future 7.x releases until the last release of the 7.x major version. This means in order to upgrade to Solr 8 in the future, you must be on Solr 7.3 or higher. [SOLR-5495](https://issues.apache.org/jira/browse/SOLR-5495)
  • SOLR-11747: The behaviour of the autoscaling system has been modified to pause all triggers from execution between the start of actions and end of cool down period. The triggers will be resumed after the cool down period expires. Previously, the cool down period was a fixed period started after actions for a trigger event complete and during this time, all triggers continued to run but any events were rejected to be tried later.
  • SOLR-11748: The throttling mechanism used to limit the rate of autoscaling events processed has been removed. This deprecates the 'actionThrottlePeriodSeconds' setting in the set-properties Autoscaling API which is now a no-op. Use the 'triggerCooldownPeriodSeconds' instead to pause event processing.
  • SOLR-11798: The top-level <highlighting> syntax in solrconfig.xml is now formally deprecated in favour of <searchComponent> equivalent syntax. See also SOLR-1696. [SOLR-1696](https://issues.apache.org/jira/browse/SOLR-1696)
  • SOLR-11809: QueryComponent's rq parameter parsing no longer considers the defType parameter.
  • SOLR-11957: The default Solr log file size and number of backups is raised to 32MB and 10 respectively
  • SOLR-12051: A new mechanism is introduced in SOLR-11702 to maintain consistency in SolrCloud between leader and replicas. This mechanism lets Solr know whether a replica is in-sync with the leader or not, even when the leader is not live. If all the replicas who participate in the leader election are out-of-sync with previous leader, the election will pause until a timeout (named "leaderVoteWait") before allowing an out-of-sync replica to become leader. Note that the new leader still needs to contains more updates than any other active replicas in the same shard. Therefore by increasing leaderVoteWait will increase the consistency (over availability) of the system. The default value of leaderVoteWait is 180,000 ms (3 minutes) and it can be adjusted in the "solrcloud" section of the solr.xml [SOLR-11702](https://issues.apache.org/jira/browse/SOLR-11702)
  • SOLR-12067: The default value of `autoReplicaFailoverWaitAfterExpiration` has been increased to 120 seconds from the earlier default of 30 seconds. This affects how soon Solr adds new replicas to replace the replicas on nodes which have either crashed or shutdown.
• Added   (44)
  • LUCENE-2899: In the Solr analysis-extras contrib, added support for the OpenNLP-based analysis components in the Lucene analysis/opennlp module: tokenization, part-of-speech tagging, phrase chunking, and lemmatization. Also added OpenNLP-based named entity extraction as a Solr update request processor.

    (Christine Poerschke, David Smiley in response to bug report, analysis from Dariusz Wojtas, Diego Ceccarelli)

Release 7.2.0 [2017-12-21]

• Upgrade Notes   (2)
  • SOLR-11501: Starting a query string with local-params {!myparser ...} is used to switch the query parser to another, and is intended for use by Solr system developers, not end users doing searches. To reduce negative side-effects of unintended hack-ability, we've limited the cases that local-params will be parsed to only contexts in which the default parser is "lucene" or "func". So if defType=edismax then q={!myparser ...} won't work. In that example, put the desired query parser into defType. Another example is if deftype=edismax then hl.q={!myparser ...} won't work for the same reason. In that example, either put the desired query parser into hl.qparser or set hl.qparser=lucene. Most users won't run into these cases but some will and must change. If you must have full backwards compatibility, use luceneMatchVersion=7.1.0 or something earlier.
    (David Smiley)
  • SOLR-11501: The edismax parser by default no longer allows subqueries that specify a Solr parser using either local-params, or the older _query_ magic field trick. For example {!prefix f=myfield v=enterp} or _query_:"{!prefix f=myfield v=enterp}" are not supported by default anymore. If you want to allow power-users to do this, set uf=* _query_ or some other value that includes _query_. If you must have full backwards compatibility, use luceneMatchVersion=7.1.0 or something earlier.

Release 7.1.0 [2017-10-17]

• Upgrade Notes   (6)
  • SOLR-10962: in the ReplicationHandler the master.commitReserveDuration sub-element is deprecated. Instead please configure a direct commitReserveDuration element for use in all modes
    (master, slave, cloud)
  • SOLR-11195: shard and cluster metric reporter configuration now requires a class attribute. If a reporter configures the group="shard" attribute then please also configure the class="org.apache.solr.metrics.reporters.solr.SolrShardReporter" attribute. If a reporter configures the group="cluster" attribute then please also configure the class="org.apache.solr.metrics.reporters.solr.SolrClusterReporter" attribute.
  • SOLR-11254: the abstract DocTransformer class now has an abstract score-less transform method variant.
  • SOLR-11283: all Stream Evaluators in solrj.io.eval have been refactored to have a simplier and more robust structure. This simplifies and condenses the code required to implement a new Evaluator and makes it much easier for evaluators to handle differing data types (primitives, objects, arrays, lists, and so forth).
    (Dennis Gove)
  • SOLR-11477: in the XML query parser
    (defType=xmlparser or {!xmlparser ... })
  • 'autoAddReplicas' feature is ported to autoscaling framework. Existing users of this feature should not have to change anything. Note these changes: 1. Behaviour: Changing the autoAddReplicas property from disabled to enabled using MODIFYCOLLECTION API no longer replaces down replicas for the collection immediately. Instead, replicas are only added if a node containing them went down while autoAddReplicas was enabled. The params autoReplicaFailoverBadNodeExpiration and autoReplicaFailoverWorkLoopDelay are no longer used. 2. Deprecations: Enabling/disabling autoAddReplicas cluster wide with the API will be deprecated; use suspend/resume trigger APIs with name='.auto_add_replicas' instead.

    (Houston Putman)
  • SOLR-10233: Add support for different replica types, that can handle updates differently: - NRT: Writes updates to transaction log and indexes locally. Replicas of type “NRT” support NRT (soft commits) and RTG. Any NRT replica can become a leader. This was the only type supported in SolrCloud until now and it’s the default type. - TLOG: Writes to transaction log, but not to index, uses replication to copy segment files from the shard leader. Any TLOG replica can become leader (by first applying all local transaction log elements). If a replica is of type TLOG but is also the leader, it will behave as a NRT. This is exactly what was added in SOLR-9835 (non-realtime replicas), just the API and naming changes. - PULL: Doesn’t index or writes to transaction log, just replicates from the shard leader. PULL replicas can’t become shard leaders (i.e., if there are only PULL replicas in the collection at some point, updates will fail same as if there is no leaders, queries continue to work), so they don’t even participate in elections.

    (David Smiley)
  • SOLR-10416: The JSON output of /admin/metrics is fixed to write the container as a map (SimpleOrderedMap) instead of an array (NamedList).
    (shalin)
  • SOLR-10420: Solr 6.x leaking one SolrZkClient instance per second
    (Scott Blum, Cao Manh Dat, Markus Jelsma, Steve Rowe)
  • SOLR-10421: Fix params persistence for solr/contrib/ltr (MinMax|Standard)Normalizer classes.
    (Jianxiong Dong, Christine Poerschke)

    (Joel Bernstein)
  • SOLR-10527: edismax with sow=false fails to create dismax-per-term queries when any field is boosted.
    (Steve Rowe)

Release 6.5.0 [2017-03-27]

• Upgrade Notes   (2)
  • SOLR-10226: JMX metric "avgTimePerRequest" (and the corresponding metric in the metrics API for each handler) used to be a simple non-decaying average based on total cumulative time and the number of requests. New Codahale Metrics implementation applies exponential decay to this value, which heavily biases the average towards the last 5 minutes.
    (ab)
  • SOLR-8593: Parallel SQL now uses Apache Calcite as its SQL framework. As part of this change the default aggregation mode has been changed to facet rather than map_reduce. There has also been changes to the SQL aggregate response and some SQL syntax changes. Consult the documentation for full details.
• Added   (31)
  • SOLR-10039: New LatLonPointSpatialField replacement for LatLonType (and some uses of RPT). Multi-value capable indexed geo lat-lon points, query by rect or circle. Efficient distance sorting/boosting too.
    (David Smiley)
  • SOLR-10085: SQL result set fields should be ordered by the field list
    (Joel Bernstein)
  • SOLR-10087: StreamHandler now supports registering custom streaming expressions from the blob store
    (Kevin Risden)
  • SOLR-10146: Added button to the Admin UI 'Collection' tab for deleting an inactive shard
    (Amrit Sarkar, janhoy)
  • SOLR-10153: & SOLR-10152: The Unified and Postings based highlighters: Add hl.bs.type=SEPARATOR along with new param hl.bs.separator to break passages by a provided single character. [SOLR-10152](https://issues.apache.org/jira/browse/SOLR-10152)
    (Amrit Sarkar, David Smiley)
  • SOLR-10156: Add significantTerms Streaming Expression
    (Joel Bernstein)
  • SOLR-10158: Add support for "preload" option in MMapDirectoryFactory.
    (Amrit Sarkar, Uwe Schindler)
  • SOLR-10224: Add disk total and disk free metrics.
    (ab)
  • SOLR-10250: CloudSolrClient can now return versions for documents added or deleted when "versions=true" is passed. However, if there is a leader election while this request is in transit, the versions may not be returned from that shard.
    (Boris Naguet, Ishan Chattopadhyaya)
  • SOLR-10254: significantTerms Streaming Expression should work in non-SolrCloud mode
    (Joel Bernstein)
  • SOLR-10286: string/text fields may now declare themselves as large="true" in the schema. Large fields are always lazy loaded and will only take up space in the document cache if the actual value is < 512KB. This option requires "stored" and must not be multiValued. It's intended for fields that might have very large values so that they don't get cached in memory.
    (David Smiley)
  • SOLR-5944: In-place updates of Numeric DocValues. To leverage this, the _version_ field and the updated field must both be stored=false, indexed=false, docValues=true.
    (Ishan Chattopadhyaya, hossman, noble, shalin, yonik)
  • SOLR-7955: Auto create .system collection on first request if it does not exist
    (noble)
  • SOLR-8029: Added new style APIs and a framework for creating new APIs and mapping old APIs to new
    (noble, Steve Rowe, Cassandra Targett, Timothy Potter)
  • SOLR-8045: Deploy V2 API at /v2 instead of /solr/v2
    (Cao Manh Dat, Noble Paul)
  • SOLR-8396: Add support for PointFields in Solr
    (Ishan Chattopadhyaya, Tomás Fernández Löbbe)
  • SOLR-8593: Integrate Apache Calcite into the SQLHandler
    (Kevin Risden, Cao Manh Dat, Joel Bernstein)
  • SOLR-9045: Make RecoveryStrategy settings configurable.
    (Christine Poerschke)
  • SOLR-9185: Solr's edismax and "Lucene"/standard query parsers will no longer split on whitespace before sending terms to analysis, if given the "sow=false" request param ("sow"=>"split on whitespace"). This enables multi-term source synonyms to match at query-time using SynonymGraphFilterFactory; other analysis components will also now work at query time, e.g. ShingleFilterFactory. By default, and when the "sow=true" param is specified, these parsers' behavior remains the same: queries will be split on whitespace before sending individual terms to analysis.
    (Steve Rowe)
  • SOLR-9481: Authentication and Authorization plugins now work in standalone mode if security.json is placed in SOLR_HOME on every node. Editing config through API is supported but affects only that one node.
    (janhoy)
  • SOLR-9836: Add ability to recover from leader when index corruption is detected on SolrCore creation.
    (Mike Drob, Mark Miller)
  • SOLR-9885: Allow pre-startup Solr log management in Solr bin scripts to be disabled.
    (Mano Kovacs, Mark Miller)
  • SOLR-9903: Stop interrupting the update executor on shutdown, it can cause graceful shutdowns to put replicas into Leader Initiated Recovery among other undesirable things.
    (Mark Miller)
  • SOLR-9912: Add facet.excludeTerms parameter support.
    (Jonny Marks, David Smiley, Christine Poerschke)
  • SOLR-9916: Adds Stream Evaluators to support evaluating values from tuples. Supports boolean, numeric, and conditional evaluators. BooleanOperations have been removed in preference of BooleanEvaluators.
    (Dennis Gove)
  • SOLR-9926: Allow passing arbitrary java system properties to zkcli.
    (Hrishikesh Gadre, Mark Miller)
  • SOLR-9933: SolrCoreParser now supports configuration of custom SpanQueryBuilder classes.
    (Daniel Collins, Christine Poerschke)
  • SOLR-9986: Implement DatePointField
    (Cao Manh Dat, Tomás Fernández Löbbe)
  • SOLR-9987: Add support for MultiValued DocValues in PointFields using SortedNumericDocValues
    (Tomás Fernández Löbbe)
  • SOLR-9997: Enable configuring SolrHttpClientBuilder via java system property.
    (Hrishikesh Gadre, Mark Miller)
  • SOLR-9999: Instrument DirectUpdateHandler2. This registers existing statistics under metrics API and adds more metrics to track the rates of update and delete commands.
    (ab)
• Changed   (5)
  • SOLR-10143: PointFields will create IndexOrDocValuesQuery when a field is both, indexed=true and docValues=true
    (Tomás Fernández Löbbe)
  • SOLR-10273: The field with the longest value (if it exceeds 4K) is moved to be last in the Lucene Document in order to benefit from stored field optimizations in Lucene that can avoid reading it when it's not needed. If the field is multi-valued, they all move together to the end to retain order.
    (David Smiley)
  • SOLR-9584: Support Solr being proxied with another endpoint than default /solr, by using relative links in AdminUI javascripts
    (Yun Jie Zhou, janhoy)
  • SOLR-9764: All filters that match all documents in the index now share the same memory (DocSet).
    (Michael Sun, yonik)
  • SOLR-9941: Clear the deletes lists at UpdateLog before replaying from log. This prevents redundantly pre-applying DBQs, during the log replay, to every update in the log as if the DBQs were out of order.
    (hossman, Ishan Chattopadhyaya)
• Fixed   (34)
  • SOLR-10020: CoreAdminHandler silently swallows some errors.
    (Mike Drob, Erick Erickson)
  • SOLR-10049: Collection deletion leaves behind the snapshot metadata
    (Hrishikesh Gadre, yonik)
  • SOLR-10055: Linux installer now renames existing bin/solr.in.* as bin/solr.in.*.orig to make the installed config in /etc/defaults be the one found by default when launching solr manually.
    (janhoy)
  • SOLR-10063: CoreContainer shutdown has race condition that can cause a hang on shutdown.
    (Mark Miller)

    (Mark Miller)
  • SOLR-10121: Fix race conditions in HDFS BlockCache that can contribute to corruption in high concurrency situations.
    (yonik)
  • SOLR-10124: Replication can skip removing a temporary index directory in some cases when it should not.
    (Mark Miller)
  • SOLR-10141: Upgrade to Caffeine 2.4.0 since v1.0.1 contributed to BlockCache corruption because the removal listener was called more than once for some items and not at all for other items.
    (Ben Manes, yonik)
  • SOLR-10159: When DBQ is reordered with an in-place update, upon whose updated value the DBQ is based on, the DBQ fails due to excessive caching in DeleteByQueryWrapper
    (Ishan Chattopadhyaya)
  • SOLR-10168: ShardSplit can fail with NPE in OverseerCollectionMessageHandler#waitForCoreAdminAsyncCallToComplete.
    (Mark Miller)
  • SOLR-10170: ClassCastException in RecoveryStrategy.
    (Mark Miller)

    (hossman, Uwe Schindler)
  • SOLR-10196: ElectionContext#runLeaderProcess can hit NPE on core close.
    (Mark Miller)
  • SOLR-10218: The Schema API commands "add-field-type" and "replace-field-type" improperly specify SimilarityFactory params.
    (Benjamin Deininger, Troy Mohl, Steve Rowe)
  • SOLR-10225: Fix HDFS BlockCache evictions metric to not count explicit removal due to a directory close.
    (yonik)
  • SOLR-10226: add back "totalTime" metric to all handlers. See also the back-compat note.

    (Tomás Fernández Löbbe, David Smiley)
  • SOLR-10269: MetricsHandler JSON output incorrect.
    (ab)
  • SOLR-10279: The autoAddReplica feature can result in SolrCores being assigned new shards when using legacyCloud=false and will also fail on a state check when taking over a core registration with a new core.
    (Mark Miller, Hrishikesh Gadre, Patrick Dvorack)
  • SOLR-10283: Learning to Rank (LTR) SolrFeature to reject searches with missing efi (External Feature Information) used by fq.

  • SOLR-10011: Refactor PointField & TrieField to now have a common base class, NumericFieldType. The TrieField.TrieTypes and PointField.PointTypes are now consolidated to NumericFieldType.NumberType. This refactoring also fixes a bug whereby PointFields were not using DocValues for range queries for indexed=false, docValues=true fields.
    (Ishan Chattopadhyaya, Tomás Fernández Löbbe)

    (Tomás Fernández Löbbe)

Release 6.4.0 [2017-01-23]

• Upgrade Notes   (5)
  • SOLR-7466: complexphrase query parser now supports leading wildcards, beware of its' possible heaviness. Users are encouraged to use ReversedWildcardFilter in index time analysis.
  • SOLR-8785: Metrics related classes in org.apache.solr.util.stats have been removed in favor of the dropwizard metrics library. Any custom plugins using these classes should be changed to use the equivalent classes from the metrics library. As part of this, the following changes were made to the output of Overseer Status API: * The "totalTime" metric has been removed because it is no longer supported * The metrics "75thPctlRequestTime", "95thPctlRequestTime", "99thPctlRequestTime" and "999thPctlRequestTime" in Overseer Status API have been renamed to "75thPcRequestTime", "95thPcRequestTime" and so on for consistency with stats output in other parts of Solr. * The metrics "avgRequestsPerMinute", "5minRateRequestsPerMinute" and "15minRateRequestsPerMinute" have been replaced by corresponding per-second rates viz. "avgRequestsPerSecond", "5minRateRequestsPerSecond" and "15minRateRequestsPerSecond" for consistency with stats output in other parts of Solr.
  • SOLR-9166: Export handler returns zero for numeric fields that are not in the original doc. One consequence of this change is that you must be aware that some tuples will not have values if there were none in the original document.
  • SOLR-9708: You are encouraged to try out the UnifiedHighlighter by setting hl.method=unified and report feedback. It might become the default in 7.0. It's more efficient/faster than the other highlighters, especially compared to the original Highlighter. That said, some options aren't supported yet. It will get more features in time, especially with your input. See HighlightParams.java for a listing of highlight parameters annotated with which highlighters use them. hl.useFastVectorHighlighter is now considered deprecated in lieu of hl.method=fastVector.
  • SOLR-9712: maxWarmingSearchers now defaults to 1, and more importantly commits will now block if this limit is exceeded instead of throwing an exception (a good thing). Consequently there is no longer a risk in overlapping commits. Nonetheless users should continue to avoid excessive committing. Users are advised to remove any pre-existing maxWarmingSearchers entries from their solrconfig.xml files.
• Added   (40)
  • SOLR-4735: Improve metrics reporting. This uses the dropwizard metric library, adding an internal API for registering and reporting metrics from Solr components. Several new metrics and an improved JMX reporter have been added [SOLR-9921](https://issues.apache.org/jira/browse/SOLR-9921)
    (Alan Woodward, Jeff Wartes, Christine Poerschke, Kelvin Wong, shalin, ab)
  • SOLR-5043: New solr.dns.prevent.reverse.lookup system property that can be used to prevent long core (re)load delays on systems with missconfigured hostname/DNS

  • SOLR-9681: FacetModule / JSON Facet API added the ability to add filters directly to any facet command. The filters are applied after any domain change operations. Example: { type:terms, field:category, filter:"user:yonik" }
    (yonik)

  • SOLR-9684: Add priority Streaming Expression
    (Joel Bernstein, David Smiley)
  • SOLR-9708: Added UnifiedSolrHighlighter, a highlighter adapter for Lucene's UnifiedHighlighter.

Introduced "hl.method" parameter which can be set to original|fastVector|postings|unified to pick the highlighter at runtime without the need to modify solrconfig from the default configuration. hl.useFastVectorHighlighter is now considered deprecated in lieu of hl.method=fastVector.
    (Timothy Rodriguez, David Smiley)

API supports four optional multi-valued parameters: - 'group' (all,jvm,jetty,node,core), - 'type' (all,counter,timer,gauge,histogram), - 'prefix' that filters the returned metrics, - 'registry' that selects one or more registries by prefix (eg. solr.jvm,solr.core.collection1) - Example: http://localhost:8983/solr/admin/metrics?group=jvm,jetty&type=counter - Example: http://localhost:8983/solr/admin/metrics?group=jvm&prefix=buffers,os - Example: http://localhost:8983/solr/admin/metrics?registry=solr.node,solr.core&prefix=ADMIN [SOLR-9911](https://issues.apache.org/jira/browse/SOLR-9911) [SOLR-9960](https://issues.apache.org/jira/browse/SOLR-9960)

  • SOLR-9772: Deriving distributed sort values (fieldSortValues) should reuse comparator and only invalidate leafComparator.
    (John Call, yonik)
  • SOLR-9786: FieldType has a new getSetQuery() method that can take a set of terms and create a more efficient query (such as TermsQuery). The solr query parser has been changed to use this method when appropriate. The parser also knows when it is being used to parse a filter and will create TermsQueries from large lists of normal terms or numbers, resulting in a query that will execute faster. This also acts to avoid BooleanQuery maximum clause limit. Query parsing itself has also been optimized, resulting in less produced garbage and 5-7% better performance.

Release 6.3.0 [2016-11-08]

• Upgrade Notes   (6)
  • SOLR-9570: We are no longer backing up solr.log and solr_gc.log files in date-stamped copies forever. If you relied on the solr_log_<date> or solr_gc_log_<date> being in the logs folder that will no longer be the case. See SOLR-9570 for details.
  • If you use the JSON Facet API (json.facet) with method=stream, you must now set sort='index asc' to get the streaming behavior; otherwise it won't stream. Reminder: "method" is a hint that doesn't change defaults of other parameters.
  • If you use the JSON Facet API (json.facet) to facet on a numeric field and if you use mincount=0 or if you set the prefix, then you will now get an error as these options are incompatible with numeric faceting.
  • Solr's logging verbosity at the INFO level has been greatly reduced, and you may need to update the log configs to use the DEBUG level to see all the logging messages you used to see at INFO level before.
  • The create/deleteCollection methods on MiniSolrCloudCluster have been deprecated. Clients should instead use the CollectionAdminRequest API. In addition, MiniSolrCloudCluster#uploadConfigDir(File, String) has been deprecated in favour of #uploadConfigSet
    (Path, String)
  • The bin/solr.in.sh (bin/solr.in.cmd on Windows) is now completely commented by default. Previously, this wasn't so, which had the effect of masking existing environment variables.

  • SOLR-5725: facet.method=enum can bypass exact counts calculation with facet.exists=true, it just returns 1 for terms which exists in result docset.
    (Alexey Kozhemiakin, Sebastian Koziel, Radoslaw Zielinski, Mikhail Khludnev)
  • SOLR-8186: Reduce logging to logs/solr-<port>-console.log when not running in foreground mode Show timestamp also in foreground log. Also removes some logging noise.

    (Uwe Schindler, Boris Steiner)
  • SOLR-9438: Shard split can be marked successful and sub-shard states switched to 'active' even when one or more sub-shards replicas do not recover due to the leader crashing or restarting between the time the replicas are created and before they can recover. This can cause data loss.

    (shalin, noble)
  • SOLR-9488: Shard split can fail to write commit data on shutdown/restart causing replicas to recover without replicating the index. This can cause data loss.
    (shalin)
  • SOLR-9490: Fixed bugs in BoolField that caused it to erroneously return "false" for all docs depending on usage
    (Colvin Cowie, Dan Fox, hossman)
  • SOLR-9494: Use of {!collapse} sometimes doesn't correctly return true for Collector.needsScores(), especially when the query was cached. This can cause an exception when 'q' is a SpanQuery or potentially others.

  • SOLR-11482: RunExecutableListener was deprecated and is disabled by default for security reasons. Legacy applications still using it must explicitely pass '-Dsolr.enableRunExecutableListener=true' to the Solr command line. Be aware that you should really disable API-based config editing at the same time, using '-Ddisable.configEdit=true'!

  • SOLR-8145: Fix position of OOM killer script when starting Solr in the background
    (Jurian Broertjes via Timothy Potter)
  • SOLR-8155: JSON Facet API - field faceting on a multi-valued string field without docValues (i.e. UnInvertedField implementation), but with a prefix or with a sort other than count, resulted in incorrect results.

    (Ishan Chattopadhyaya, yonik)

  • SOLR-4280: Allow specifying "spellcheck.maxResultsForSuggest" as a percentage of filter query results
    (Markus Jelsma, James Dyer)
  • SOLR-4619: Improve PreAnalyzedField query analysis.
    (Andrzej Bialecki, Steve Rowe)
  • SOLR-5743: BlockJoinFacetComponent and BlockJoinDocSetFacetComponent for calculating facets by child.facet.field parameter with {!parent ..}.. query. They count facets on children documents aggregating (deduplicating) counts by parent documents
    (Dr. Oleg Savrasov, Mikhail Khludnev)

    (Mike Drob, Gregory Chanan)

    (Michael Sun, yonik)
  • SOLR-8312: Add domain size and numBuckets to facet telemetry info (facet debug info for the new Facet Module).
    (Michael Sun, yonik)
  • SOLR-8378: Add upconfig and downconfig commands to the bin/solr script
    (Erick Erickson)
  • SOLR-839: XML QueryParser support (defType=xmlparser) Lucene includes a queryparser that supports the creation of Lucene queries from XML. The queries supported by lucene.queryparser.xml.CoreParser are now supported by the newly created solr.search.SolrCoreParser and in future SolrCoreParser could support additional queries also. Example: <BooleanQuery fieldName="description"> <Clause occurs="must"> <TermQuery>shirt</TermQuery> </Clause> <Clause occurs="mustnot"> <TermQuery>plain</TermQuery> </Clause> <Clause occurs="should"> <TermQuery>cotton</TermQuery> </Clause> <Clause occurs="must"> <BooleanQuery fieldName="size"> <Clause occurs="should"> <TermsQuery>S M L</TermsQuery> </Clause> </BooleanQuery> </Clause> </BooleanQuery>

  • SOLR-8429: Add a flag 'blockUnknown' to BasicAuthPlugin to block unauthenticated requests
    (noble)
  • SOLR-8434: Add wildcard support to role, to match any role in RuleBasedAuthorizationPlugin
    (noble)
  • SOLR-8466: adding facet.method=uif to bring back UnInvertedField faceting which is used to work on facet.method=fc. It's more performant for rarely changing indexes. Note: it ignores prefix and contains yet.
    (Jamie Johnson, Mikhail Khludnev)
  • SOLR-8470: Make TTL of PKIAuthenticationPlugin's tokens configurable through a system property
    (pkiauth.ttl, noble)
  • SOLR-8477: Let users choose compression mode in SchemaCodecFactory
    (Tomás Fernández Löbbe)
  • SOLR-8500: Allow the number of threads ConcurrentUpdateSolrClient StreamingSolrClients configurable by a system property. NOTE: this is an expert option and can result in more often needing to do full index replication for recovery, the sweet spot for using this is very high volume, leader-only indexing.
    (Tim Potter, Erick Erickson)
  • SOLR-8534: Add generic support for collection APIs to be async. Thus more actions benefit from having async support. The commands that additionally get async support are: delete/reload collection, create/delete alias, create/delete shard, delete replica, add/delete replica property, add/remove role, overseer status, balance shard unique, rebalance leaders, modify collection, migrate state format
    (Varun Thacker)
  • SOLR-8560: Added RequestStatusState enum which can be used when comparing states of asynchronous requests.
    (Shai Erera)
  • SOLR-8586: added index fingerprint, a hash over all versions currently in the index. PeerSync now uses this to check if replicas are in sync.
    (yonik)
  • SOLR-8621: Deprecate <mergePolicy> in favor of <mergePolicyFactory>. It allows to configure both the "simple" merge policies, but also more advanced ones, e.g. UpgradeIndexMergePolicy.
    (Christine Poerschke, Shai Erera)
  • SOLR-8642: SOLR allows creation of collections with invalid names
    (Jason Gerlowski, Erick Erickson)

    (Mark Miller, shalin)
  • SOLR-8501: Specify the entity request size when known in HttpSolrClient.
    (Mark Miller)
  • SOLR-8615: Just like creating cores, we should use multiple threads when closing cores.
    (Mark Miller)
  • SOLR-8669: Non binary responses use chunked encoding because we flush the outputstream early.
    (Mark Miller)
• Fixed   (35)
  • SOLR-2556: The default spellcheck query converter was ignoring terms consisting entirely of digits.
    (James Dyer)
  • SOLR-2649: MM ignored in edismax queries with operators.
    (Greg Pendlebury, Jan Høydahl et. al., Erick Erickson)

    (Mark Miller)
  • SOLR-8059: &debug=results for distributed search when distrib.singlePass (sometimes activated automatically) could result in an NPE.
    (David Smiley, Markus Jelsma)
  • SOLR-8175: Word Break Spellchecker would throw AIOOBE with certain queries containing "should" clauses.
    (Ryan Josal, James Dyer)
  • SOLR-8276: Atomic updates and realtime-get do not work with non-stored docvalues.
    (Ishan Chattopadhyaya, yonik, shalin)
  • SOLR-8366: ConcurrentUpdateSolrClient attempts to use response's content type as charset encoding for parsing exception.
    (shalin)
  • SOLR-8367: Fix the LeaderInitiatedRecovery 'all replicas participate' fail-safe.
    (Mark Miller, Mike Drob)
  • SOLR-8371: Try and prevent too many recovery requests from stacking up and clean up some faulty cancel recovery logic.
    (Mark Miller)
  • SOLR-8372: Canceled recovery can rarely lead to inconsistent shards: If a replica is recovering via index replication, and that recovery fails (for example if the leader goes down), and then some more updates are received (there could be a few left to be processed from the leader that just went down), and then that replica is brought down, it will think it is up-to-date when restarted.
    (shalin, Mark Miller, yonik)
  • SOLR-8373: KerberosPlugin: Using multiple nodes on same machine leads clients to fetch TGT for every request
    (Ishan Chattopadhyaya, noble)
  • SOLR-8401: Windows start script fails when executed from a different drive.
    (Nicolas Gavalda, Erick Erickson)
  • SOLR-8419: TermVectorComponent for distributed search when distrib.singlePass could include term vectors for documents that matched the query yet weren't in the returned documents.
    (David Smiley)
  • SOLR-8422: When authentication enabled, requests fail if sent to a node that doesn't host the collection
    (noble)
  • SOLR-8450: Our HttpClient retry policy is too permissive.
    (Mark Miller, shalin)
  • SOLR-8451: We should not call method.abort in HttpSolrClient or HttpSolrCall#remoteQuery and HttpSolrCall#remoteQuery should not close streams.
    (Mark Miller)
  • SOLR-8453: Solr should attempt to consume the request inputstream on errors as we cannot count on the container to do it.
    (Mark Miller, Greg Wilkins, yonik, Joakim Erdfelt)
  • SOLR-8460: /analysis/field could throw exceptions for custom attributes.
    (David Smiley, Uwe Schindler)
  • SOLR-8494: SimplePostTool and therefore the bin/post script cannot upload files larger than 2.1GB.
    (shalin)
  • SOLR-8533: Raise default maxUpdateConnections and maxUpdateConnectionsPerHost to 100k each.
    (Mark Miller)

    (Mark Miller, Patrick Dvorack, yonik)

    (noble, shalin)

    (David Smiley)
  • LUCENE-6925: add RandomForceMergePolicy class in test-framework
    (Christine Poerschke)
  • LUCENE-6978: Refactor several code places that lookup locales by string name to use BCP47 locale tag instead. LuceneTestCase now also prints locales on failing tests this way. In addition, several places in Solr now additionally support BCP47 in config files.
    (Uwe Schindler, Robert Muir)
  • SOLR-3141: Warn in logs when expensive optimize calls are made
    (yonik, janhoy)

    (Christine Poerschke)
  • SOLR-7907: Remove CLUSTERSTATUS related exclusivity checks while running commands in the Overseer because the CLUSTERSTATUS request is served by the individual nodes itself and not via the Overseer node
    (Varun Thacker)
  • SOLR-7968: Make QueryComponent more extensible.
    (Markus Jelsma, David Smiley)
  • SOLR-8131: All example config sets now explicitly use the ManagedIndexSchemaFactory instead of ClassicIndexSchemaFactory. This means that the Schema APIs ( /<collection>/schema ) are enabled by default and the schema is mutable. The schema file will be called managed-schema
    (Uwe Schindler, shalin, Varun Thacker)
  • SOLR-8279: Add a new test fault injection approach and a new SolrCloud test that stops and starts the cluster while indexing data and with random faults.
    (Mark Miller)

    (yonik)
  • SOLR-7971: Reduce memory allocated by JavaBinCodec to encode small strings by an amount equal to the string.length(). JavaBinCodec now uses a double pass approach to write strings larger than 64KB to avoid allocating buffer memory equal to string's UTF8 size.
    (yonik, Steve Rowe, Mikhail Khludnev, Noble Paul, shalin)

  • SOLR-7836: Possible deadlock when closing refcounted index writers.
    (Jessica Cheng Mallet, Erick Erickson, Mark Miller, yonik)

    (hossman)
  • SOLR-7956: There are interrupts on shutdown in places that can cause ChannelAlreadyClosed exceptions which prevents proper closing of transaction logs, interfere with the IndexWriter, the hdfs client and other things.
    (Mark Miller, Scott Blum)
  • SOLR-7967: AddSchemaFieldsUpdateProcessorFactory does not check if the ConfigSet is immutable
    (Gregory Chanan)
  • SOLR-7984: wrong and misleading error message 'no default request handler is registered'
    (noble, hossman)

    (Mikhail Khludnev, Vadim Kirilchuk, Alan Woodward, Tom Burton-West, Mike McCandless, hossman, yonik)
  • SOLR-3240: Add "spellcheck.collateMaxCollectDocs" option so that when testing potential Collations against the index, SpellCheckComponent will only collect n documents, thereby estimating the hit-count. This is a performance optimization in cases where exact hit-counts are unnecessary. Also, when "collateExtendedResults" is false, this optimization is always made
    (James Dyer)
  • SOLR-3251: Dynamically add fields to schema.
    (Steve Rowe, Robert Muir, yonik)
  • SOLR-4048: Add findRecursive method to NamedList.

  • SOLR-4785: New MaxScoreQParserPlugin returning max() instead of sum() of terms
    (janhoy)
  • SOLR-4892: Add FieldMutatingUpdateProcessorFactory subclasses Parse{Date,Integer,Long,Float,Double,Boolean}UpdateProcessorFactory. These factories have a default selector that matches all fields that either don’t match any schema field, or are in the schema with the corresponding typeClass. If they see a value that is not a CharSequence, or can't parse the value, they leave it as is. For multi-valued fields, these processors will not convert any values unless all are first successfully parsed, or already are instances of the target class. Ordering the processors, e.g. [Boolean, Long, Double, Date] will allow e.g. values ["2", "5", "8.6"] to be left alone by the Boolean and Long processors, but then converted by the Double processor.
    (Steve Rowe, hossman)
  • SOLR-4893: Extend FieldMutatingUpdateProcessor.ConfigurableFieldNameSelector to enable checking whether a field matches any schema field. To select field names that don't match any fields or dynamic fields in the schema, add <bool name="fieldNameMatchesSchemaField">false</bool> to an update processor's configuration in solrconfig.xml.
    (Steve Rowe, hossman)
  • SOLR-4897: Add solr/example/example-schemaless/, an example config set for schemaless mode.

    (hossman)
  • SOLR-4805: SolrCore#reload should not call preRegister and publish a DOWN state to ZooKeeper.
    (Mark Miller, Jared Rodriguez)
  • SOLR-4814: If a SolrCore cannot be created it should remove any information it published about itself from ZooKeeper.
    (Mark Miller)
  • SOLR-4842: Fix facet.field local params from affecting other facet.field's.
    (ehatcher, hossman)
  • SOLR-4863: Removed non-existent attribute sourceId from dynamic JMX stats to fix AttributeNotFoundException

    (Mark Miller)
  • SOLR-4910: persisting solr.xml is broken. More stringent testing of persistence fixed up a number of issues and several bugs with persistence. Among them are - don't persisting implicit properties - should persist zkHost in the <solr> tag (user's list) - reloading a core that has transient="true" returned an error. reload should load a transient core if it's not yet loaded. - No longer persisting loadOnStartup or transient core properties if they were not specified in the original solr.xml - Testing flushed out the fact that you couldn't swap a core marked transient=true loadOnStartup=false because it hadn't been loaded yet. - SOLR-4862, CREATE fails to persist schema, config, and dataDir - SOLR-4363, not persisting coreLoadThreads in <solr> tag - SOLR-3900, logWatcher properties not persisted - SOLR-4850, cores defined as loadOnStartup=true, transient=false can't be searched [SOLR-4862](https://issues.apache.org/jira/browse/SOLR-4862) [SOLR-4363](https://issues.apache.org/jira/browse/SOLR-4363) [SOLR-3900](https://issues.apache.org/jira/browse/SOLR-3900) [SOLR-4850](https://issues.apache.org/jira/browse/SOLR-4850)
    (Erick Erickson)
  • SOLR-4915: The root cause should be returned to the user when a SolrCore create call fails.
    (Mark Miller)
  • SOLR-4920: JdbcDataSource incorrectly suppresses exceptions when retrieving a connection from a JNDI context and falls back to trying to use DriverManager to obtain a connection. Additionally, if a SQLException is thrown while initializing a connection, such as in setAutoCommit(), the connection will not be closed.
    (Chris Eldredge, shalin)
  • SOLR-4923: Commits to non leaders as part of a request that also contain updates can execute out of order.

  • SOLR-4925: Collection create throws NPE when 'numShards' param is missing
    (Noble Paul)
  • SOLR-4926: Fixed rare replication bug that normally only manifested when using compound file format.
    (yonik, Mark Miller)
  • SOLR-4932: persisting solr.xml saves some parameters it shouldn't when they weren't defined in the original. Benign since the default values are saved, but still incorrect.
    (Erick Erickson, thanks Shawn Heisey for helping test!)
  • SOLR-4934: Fix handling of <mergePolicy> init arg "useCompoundFile" needed after changes in LUCENE-5038 [SOLR-4941](https://issues.apache.org/jira/browse/SOLR-4941) [LUCENE-5038](https://issues.apache.org/jira/browse/LUCENE-5038)

  • SOLR-4978: Time is stripped from datetime column when imported into Solr date field if convertType=true.
    (Bill Au, shalin)
  • SOLR-4982: Creating a core while referencing system properties looks like it loses files Actually, instanceDir, config, dataDir and schema are not dereferenced properly when creating cores that reference sys vars (e.g. &dataDir=${dir}). In the dataDir case in particular this leads to the index being put in a directory literally named ${dir} but on restart the sysvar will be properly dereferenced.
  • SOLR-4997: The splitshard api doesn't call commit on new sub shards before switching shard states. Multiple bugs related to sub shard recovery and replication are also fixed.
    (shalin)
  • SOLR-5000: ManagedIndexSchema doesn't persist uniqueKey tag after calling addFields method.

  • SOLR-4797: Shard splitting creates sub shards which have the wrong hash range in cluster state. This happens when numShards is not a power of two and router is compositeId.
    (shalin)
  • SOLR-4798: shard splitting does not respect the router for the collection when executing the index split. One effect of this is that documents may be placed in the wrong shard when the default compositeId router is used in conjunction with IDs containing "!".

Release 4.3.0 [2013-05-06]

• Added   (11)
  • SOLR-3755: A new collections api to add additional shards dynamically by splitting existing shards.
    (yonik, Anshum Gupta, shalin)
  • SOLR-4358: HttpSolrServer sends the stream name and exposes 'useMultiPartPost'
    (Karl Wright, ryan)
  • SOLR-4530: DIH: Provide configuration to use Tika's IdentityHtmlMapper
    (Alexandre Rafalovitch, shalin)
  • SOLR-4623: Provide REST API read access to all elements of the live schema. Add a REST API request to return the entire live schema, in JSON, XML, and schema.xml formats. Move REST API methods from package org.apache.solr.rest to org.apache.solr.rest.schema, and rename base functionality REST API classes to remove the current schema focus, to prepare for other non-schema REST APIs. Change output path for copyFields and dynamicFields from "copyfields" and "dynamicfields" (all lowercase) to "copyFields" and "dynamicFields", respectively, to align with all other REST API outputs, which use camelCase.
    (Steve Rowe)
  • SOLR-4648: PreAnalyzedUpdateProcessorFactory allows using the functionality of PreAnalyzedField with other field types. See javadoc for details and examples.
    (Andrzej Bialecki)
  • SOLR-4656: Added two new highlight parameters, hl.maxMultiValuedToMatch and hl.maxMultiValuedToExamine. maxMultiValuedToMatch stops looking for snippets after finding the specified number of matches, no matter how far into the multivalued field you've gone. maxMultiValuedToExamine stops looking for matches after the specified number of multiValued entries have been examined. If both are specified, the limit hit first stops the loop. Also this patch cuts down on the copying of the document entries during highlighting. These optimizations are probably unnoticeable unless there are a large number of entries in the multiValued field. Conspicuously, this will prevent the "best" match from being found if it appears later in the MV list than the cutoff specified by either of these params.
    (Erick Erickson)
  • SOLR-4658: In preparation for REST API requests that can modify the schema, a "managed schema" is introduced. Add '<schemaFactory class="ManagedSchemaFactory" mutable="true"/>' to solrconfig.xml in order to use it, and to enable schema modifications via REST API requests.
    (Steve Rowe, Robert Muir)
  • SOLR-4662: Discover SolrCores by directory structure rather than defining them in solr.xml. Also, change the format of solr.xml to be closer to that of solrconfig.xml. This version of Solr will ship the example in the old style, but you can manually try the new style. Solr 4.4 will ship with the new style, and Solr 5.0 will remove support for the old style. (Erick Erickson, Mark Miller) Additional Work: - SOLR-4347: Ensure that newly-created cores via Admin handler are persisted in solr.xml (Erick Erickson) - SOLR-1905: Cores created by the admin request handler should be persisted to solr.xml. Also fixed a problem whereby properties like solr.solr.datadir would be persisted to solr.xml. Also, cores that didn't happen to be loaded were not persisted.

    (Mark Miller)

Release 4.1.0 [2013-01-22]

• Added   (35)
  • SOLR-1028: The ability to specify "transient" and "loadOnStartup" as a new properties of <core> tags in solr.xml. Can specify "transientCacheSize" in the <cores> tag. Together these allow cores to be loaded only when needed and only transientCacheSize transient cores will be loaded at a time, the rest aged out on an LRU basis.
  • SOLR-1972: Add extra statistics to RequestHandlers - 5 & 15-minute reqs/sec rolling averages; median, 75th, 95th, 99th, 99.9th percentile request times
    (Alan Woodward, Shawn Heisey, Adrien Grand, Uwe Schindler)
  • SOLR-2201: DIH's "formatDate" function now supports a timezone as an optional fourth parameter
    (James Dyer, Mark Waddle)
  • SOLR-2255: Enhanced pivot faceting to use local-params in the same way that regular field value faceting can. This means support for excluding a filter query, using a different output key, and specifying 'threads' to do facet.method=fcs concurrently. PivotFacetHelper now extends SimpleFacet and the getFacetImplementation() extension hook was removed.
    (dsmiley)
  • SOLR-2592: Collection specific document routing. The "compositeId" router is the default for collections with hash based routing (i.e. when numShards=N is specified on collection creation). Documents with ids sharing the same domain (prefix) will be routed to the same shard, allowing for efficient querying. Example: The following two documents will be indexed to the same shard since they share the same domain "customerB!". <code> {"id" : "customerB!doc1" [...] } {"id" : "customerB!doc2" [...] } </code> At query time, one can specify a "shard.keys" parameter that lists what shards the query should cover. http://.../query?q=my_query&shard.keys=customerB! Collections that do not specify numShards at collection creation time use custom sharding and default to the "implicit" router. Document updates received by a shard will be indexed to that shard, unless a "_shard_" parameter or document field names a different shard.
    (Michael Garski, Dan Rosher, yonik)
  • SOLR-3531: Allowing configuring maxMergeSizeMB and maxCachedMB when using NRTCachingDirectoryFactory.
    (Andy Laird, Mark Miller)
  • SOLR-3897: A highlighter parameter "hl.preserveMulti" to return all of the values of a multiValued field in their original order when highlighting.
    (Joel Bernstein, yonik)
  • SOLR-3906: Add support for AnalyzingSuggester (LUCENE-3842), where the underlying analyzed form used for suggestions is separate from the returned text. [LUCENE-3842](https://issues.apache.org/jira/browse/LUCENE-3842)
    (Robert Muir)
  • SOLR-3911: Make Directory and DirectoryFactory first class so that the majority of Solr's features work with any custom implementations. (Mark Miller) Additional Work: - SOLR-4032: Files larger than an internal buffer size fail to replicate. (Mark Miller, Markus Jelsma) - SOLR-4033: Consistently use the solrconfig.xml lockType everywhere. (Mark Miller, Markus Jelsma) - SOLR-4144: Replication using too much RAM. (yonik, Markus Jelsma) - SOLR-4187: NPE on Directory release [SOLR-4032](https://issues.apache.org/jira/browse/SOLR-4032) [SOLR-4033](https://issues.apache.org/jira/browse/SOLR-4033) [SOLR-4144](https://issues.apache.org/jira/browse/SOLR-4144) [SOLR-4187](https://issues.apache.org/jira/browse/SOLR-4187)

  • SOLR-3985: ExternalFileField caches can be reloaded on firstSearcher/ newSearcher events using the ExternalFileFieldReloader
    (Alan Woodward)
  • SOLR-4028: When using ZK chroot, it would be nice if Solr would create the initial path when it doesn't exist.
    (Tomás Fernández Löbbe, Mark Miller)
  • SOLR-4030: Allow rate limiting Directory IO based on the IO context.
    (Mark Miller, Radim Kolar)
  • SOLR-4051: Add <propertyWriter /> element to DIH's data-config.xml file, allowing the user to specify the location, filename and Locale for the "data-config.properties" file. Alternatively, users can specify their own property writer implementation for greater control. This new configuration element is optional, and defaults mimic prior behavior. The one exception is that the "root" locale is default. Previously it was the machine's default locale.
    (James Dyer)
  • SOLR-4084: Add FuzzyLookupFactory, which is like AnalyzingSuggester except that it can tolerate typos in the input.
    (Areek Zillur, Robert Muir)
  • SOLR-4087: Add MAX_DOC_FREQ option to MoreLikeThis.
    (Andrew Janowczyk, Mark Miller)
  • SOLR-4088: New and improved auto host detection strategy for SolrCloud.
    (Raintung Li, Mark Miller)
  • SOLR-4093: Solr QParsers may now be directly invoked in the lucene query syntax without the _query_ magic field hack. Example: foo AND {!term f=myfield v=$qq}
    (yonik)
  • SOLR-4101: Add support for storing term offsets in the index via a 'storeOffsetsWithPositions' flag on field definitions in the schema.
    (Tom Winch, Alan Woodward)
  • SOLR-4110: Configurable Content-Type headers for PHPResponseWriters and PHPSerializedResponseWriter.
    (Dominik Siebel, Mark Miller)
  • SOLR-4114: Allow creating more than one shard per instance with the Collection API.
    (Per Steffensen, Mark Miller)
  • SOLR-4118: Fix replicationFactor to align with industry usage. replicationFactor now means the total number of copies of a document stored in the collection (or the total number of physical indexes for a single logical slice of the collection). For example if replicationFactor=3 then for a given shard there will be a total of 3 replicas
    (one of which will normally be designated as the leader., yonik)
  • SOLR-4120: Collection API: Support for specifying a list of Solr addresses to spread a new collection across.
    (Per Steffensen, Mark Miller)
  • SOLR-4124: You should be able to set the update log directory with the CoreAdmin API the same way as the data directory.
    (Mark Miller)
  • SOLR-4140: Allow access to the collections API through CloudSolrServer without referencing an existing collection.
    (Per Steffensen, Mark Miller)
  • SOLR-4166: LBHttpSolrServer ignores ResponseParser passed in constructor.
    (Steve Molloy, Mark Miller)
  • SOLR-4230: The new Solr 4 spatial fields now work with the {!geofilt} and {!bbox} query parsers. The score local-param works too.
    (David Smiley)
  • SOLR-4246: When update.distrib is set to skip update processors before the distributed update processor, always include the log update processor so forwarded updates will still be logged.
    (yonik)
  • SOLR-4255: The new Solr 4 spatial fields now have a 'filter' boolean local-param that can be set to false to not filter. It's useful when there is already a spatial filter query but you also need to sort or boost by distance.
    (David Smiley)
  • SOLR-4265: Solr now parses request parameters (in URL or sent with POST using content-type application/x-www-form-urlencoded) in its dispatcher code. It no longer relies on special configuration settings in Tomcat or other web containers to enable UTF-8 encoding, which is mandatory for correct Solr behaviour. Query strings passed in via the URL need to be properly-%-escaped, UTF-8 encoded bytes, otherwise Solr refuses to handle the request. The maximum length of x-www-form-urlencoded POST parameters can now be configured through the requestDispatcher/requestParsers/@formdataUploadLimitInKB setting in solrconfig.xml (defaults to 2 MiB). Solr now works out of the box with e.g. Tomcat, JBoss,... [SOLR-4283](https://issues.apache.org/jira/browse/SOLR-4283)
    (Uwe Schindler, Dawid Weiss, Alex Rocher)

    (Mark Miller, yonik)
  • SOLR-4287: Removed "apache-" prefix from Solr distribution and artifact filenames.
    (Ryan Ernst, Robert Muir, Steve Rowe)
  • SOLR-4308: Remove the problematic and now unnecessary log4j-over-slf4j.
    (Mark Miller)

Release 4.0.0 [2012-10-12]

• Added   (83)
  • LUCENE-2510: Migrated Solr's Tokenizer-, TokenFilter-, and CharFilterFactories to the lucene-analysis module. To add new analysis modules to Solr (like ICU, SmartChinese, Morfologik,...), just drop in the JAR files from Lucene's binary distribution into your Solr instance's lib folder. The factories are automatically made available with SPI. [LUCENE-4044](https://issues.apache.org/jira/browse/LUCENE-4044)
    (Chris Male, Robert Muir, Uwe Schindler)
  • LUCENE-4201: Added JapaneseIterationMarkCharFilterFactory to normalize Japanese iteration marks.
    (Robert Muir, Christian Moen)
  • SOLR-1032: CSV handler now supports "literal.field_name=value" parameters.
    (Simon Rosenthal, ehatcher)
  • SOLR-1280: Added commented-out example of the new script update processor to the example configuration.
    (ehatcher)
  • SOLR-1298: Return FunctionQuery as pseudo field. The solr 'fl' param now supports functions. For example: fl=id,sum(x,y) -- NOTE: only functions with fast random access are recommended.
    (yonik, ryan)
  • SOLR-139: Change to updateable documents to create the document if it doesn't already exist. To assert that the document must exist, use the optimistic concurrency feature by specifying a _version_ of 1.
    (yonik)
  • SOLR-139: Updateable documents. JSON Example: {"id":"mydoc", "f1":{"set":10}, "f2":{"add":20}} will result in field "f1" being set to 10, "f2" having an additional value of 20 added, and all other existing fields unchanged. All source fields must be stored for this feature to work correctly.
    (Ryan McKinley, Erik Hatcher, yonik)
  • SOLR-1535: PreAnalyzedField type provides a functionality to index (and optionally store) field content that was already processed and split into tokens using some external processing chain. Serialization format is pluggable, and defaults to JSON.
    (ab)
  • SOLR-1566: Transforming documents in the ResponseWriters. This will allow for more complex results in responses and open the door for function queries as results. (ryan with patches from grant, noble, cmale, yonik, Jan Høydahl, Arul Kalaipandian, Luca Cavanna, hossman) - SOLR-2037: Thanks to SOLR-1566, documents boosted by the QueryElevationComponent can be marked as boosted. [SOLR-2037](https://issues.apache.org/jira/browse/SOLR-2037)
    (gsingers, ryan, yonik)
  • SOLR-1665: Add debug component options for timings, results and query info only
    (gsingers, hossman, yonik)
  • SOLR-1725: StatelessScriptUpdateProcessorFactory allows users to implement the full ScriptUpdateProcessor API using any scripting language with a javax.script.ScriptEngineFactory
    (Uri Boness, ehatcher, Simon Rosenthal, hossman)
  • SOLR-1856: In Solr Cell, literals should override Tika-parsed values. Patch adds a param "literalsOverride" which defaults to true, but can be set to "false" to let Tika-parsed values be appended to literal values
    (Chris Harris, janhoy)
  • SOLR-1873: SolrCloud - added shared/central config and core/shard management via zookeeper, built-in load balancing, and distributed indexing. (Jamie Johnson, Sami Siren, Ted Dunning, yonik, Mark Miller) Additional Work: - SOLR-2324: SolrCloud solr.xml parameters are not persisted by CoreContainer. (Massimo Schiavon, Mark Miller) - SOLR-2287: Allow users to query by multiple, compatible collections with SolrCloud. (Soheb Mahmood, Alex Cowell, Mark Miller) - SOLR-2622: ShowFileRequestHandler does not work in SolrCloud mode. (Stefan Matheis, Mark Miller) - SOLR-3108: Error in SolrCloud's replica lookup code when replica's are hosted in same Solr instance. (Bruno Dumon, Sami Siren, Mark Miller) - SOLR-3080: Remove shard info from zookeeper when SolrCore is explicitly unloaded. (yonik, Mark Miller, siren) - SOLR-3437: Recovery issues a spurious commit to the cluster. (Trym R. Møller via Mark Miller) - SOLR-2822: Skip update processors already run on other nodes [SOLR-2358](https://issues.apache.org/jira/browse/SOLR-2358) [SOLR-2324](https://issues.apache.org/jira/browse/SOLR-2324) [SOLR-2287](https://issues.apache.org/jira/browse/SOLR-2287) [SOLR-2622](https://issues.apache.org/jira/browse/SOLR-2622) [SOLR-3108](https://issues.apache.org/jira/browse/SOLR-3108) [SOLR-3080](https://issues.apache.org/jira/browse/SOLR-3080) [SOLR-3437](https://issues.apache.org/jira/browse/SOLR-3437) [SOLR-2822](https://issues.apache.org/jira/browse/SOLR-2822)
    (hossman)
  • SOLR-1929: Index encrypted documents with ExtractingUpdateRequestHandler. By supplying resource.password=<mypw> or specifying an external file with regular expressions matching file names, Solr will decrypt and index PDFs and DOCX formats.
    (janhoy, Yiannis Pericleous)
  • SOLR-1932: New relevancy function queries: termfreq, tf, docfreq, idf norm, maxdoc, numdocs.
    (yonik)
  • SOLR-1942: Added the ability to select postings format per fieldType in schema.xml as well as support custom Codecs in solrconfig.xml.
    (simonw)
  • SOLR-2058: Edismax query parser to allow "phrase slop" to be specified per-field on the pf/pf2/pf3 parameters using optional "FieldName~slop^boost" syntax. The prior "FieldName^boost" syntax is still accepted. In such cases the value on the "ps" parameter serves as the default slop.
    (Ron Mayer)
  • SOLR-2112: Solrj API now supports streaming results.
    (ryan)
  • SOLR-2134: Trie* fields should support sortMissingLast=true, and deprecate Sortable* Field Types
    (Ryan McKinley, Mike McCandless, Uwe Schindler, Erick Erickson)
  • SOLR-2136: Boolean type added to function queries, along with new functions exists(), if(), and(), or(), xor(), not(), def(), and true and false constants.
    (yonik)
  • SOLR-2193: You may now specify a 'soft' commit when committing. This will use Lucene's NRT feature to avoid guaranteeing documents are on stable storage in exchange for faster reopen times. There is also a new 'soft' autocommit tracker that can be configured. [SOLR-2565](https://issues.apache.org/jira/browse/SOLR-2565)
    (Mark Miller, Robert Muir)
  • SOLR-2272: Pseudo-join queries / filters. Examples: - To restrict to the set of parents with at least one blue-eyed child: fq={!join from=parent to=name}eyes:blue - To restrict to the set of children with at least one blue-eyed parent: fq={!join from=name to=parent}eyes:blue
    (yonik)
  • SOLR-2335: New 'field("...")' function syntax for referring to complex field names (containing whitespace or special characters) in functions.
  • SOLR-2338: Add support for using <similarity/> in a schema's fieldType, for customizing scoring on a per-field basis.
    (hossman, yonik, rmuir)
  • SOLR-2383: /browse improvements: generalize range and date facet display
    (Jan Høydahl)
  • SOLR-2396: Add CollationField, which is much more efficient than the Solr 3.x CollationKeyFilterFactory, and also supports Locale-sensitive range queries.
    (rmuir)
  • SOLR-2396: Add ICUCollationField to contrib/analysis-extras, which is much more efficient than the Solr 3.x ICUCollationKeyFilterFactory, and also supports Locale-sensitive range queries.
    (rmuir)
  • SOLR-2399: Updated Solr Admin interface. New look and feel with per core administration and many new options.
    (Stefan Matheis)
  • SOLR-2417: Add explain info directly to return documents using ?fl=id,[explain]
    (ryan)
  • SOLR-2438: added MultiTermAwareComponent to the various classes to allow automatic lowercasing for multiterm queries (wildcards, regex, prefix, range, etc). You can now optionally specify a "multiterm" analyzer in our schema.xml, but Solr should "do the right thing" if you don't specify <analyzer type="multiterm">
    (Pete Sturge Erick Erickson, Mentoring from Seeley, Muir)
  • SOLR-2459: Expose LogLevel selection with a RequestHandler rather then servlet
    (Stefan Matheis, Upayavira, ryan)
  • SOLR-2481: Add support for commitWithin in DataImportHandler
    (Sami Siren)
  • SOLR-2491: Add support for using spellcheck collation in conjunction with grouping. Note that the number of hits returned for collations is the number of ungrouped hits.
    (James Dyer)
  • SOLR-2533: Converted ValueSource.ValueSourceSortField over to new rewriteable Lucene SortFields. ValueSourceSortField instances must be rewritten before they can be used. This is done by SolrIndexSearcher when necessary.
    (Chris Male)
  • LUCENE-2507: Added DirectSolrSpellChecker, which uses Lucene's DirectSpellChecker to retrieve correction candidates directly from the term dictionary using levenshtein automata. [SOLR-2571](https://issues.apache.org/jira/browse/SOLR-2571) [SOLR-2576](https://issues.apache.org/jira/browse/SOLR-2576)
    (James Dyer, rmuir)
  • SOLR-2585: Context-Sensitive Spelling Suggestions & Collations. This adds support for the "spellcheck.alternativeTermCount" & "spellcheck.maxResultsForSuggest" parameters, letting users receive suggestions even when all the queried terms exist in the dictionary. This differs from "spellcheck.onlyMorePopular" in that the suggestions need not consist entirely of terms with a greater document frequency than the queried terms.
    (James Dyer)
  • SOLR-2599: CloneFieldUpdateProcessorFactory provides similar functionality to schema.xml's <copyField/> declaration but as an update processor that can be combined with other processors in any order.
    (Jan Høydahl & hossman)
  • SOLR-2616: Include a sample java util logging configuration file.
    (David Smiley, Mark Miller)
  • SOLR-2656: realtime-get, efficiently retrieves the latest stored fields for specified documents, even if they are not yet searchable
    (i.e. without reopening a searcher, yonik)
  • SOLR-2690: New support for a "TZ" request param which overrides the TimeZone used when rounding Dates in DateMath expressions for the entire request (all date range queries and date faceting is affected). The default TZ is still UTC.
    (David Schlotfeldt, hossman)
  • SOLR-2702: The default directory factory was changed to NRTCachingDirectoryFactory which wraps the StandardDirectoryFactory and caches small files for improved Near Real-time (NRT) performance.
    (Mark Miller, yonik)
  • SOLR-2703: Added support for Lucene's "surround" query parser.
    (Simon Rosenthal, ehatcher)
  • SOLR-2754: Added factories for several ranking algorithms: - BM25SimilarityFactory: Okapi BM25 - DFRSimilarityFactory: Divergence from Randomness models - IBSimilarityFactory: Information-based models - LMDirichletSimilarity: LM with Dirichlet smoothing - LMJelinekMercerSimilarity: LM with Jelinek-Mercer smoothing
    (David Mark Nemeskey, Robert Muir)
  • SOLR-2768: new "mod(x,y)" function for computing the modulus of two value sources.
    (hossman)
  • SOLR-2802: New FieldMutatingUpdateProcessor and Factory to simplify the development of UpdateProcessors that modify field values of documents as they are indexed. Also includes several useful new implementations: - RemoveBlankFieldUpdateProcessorFactory - TrimFieldUpdateProcessorFactory - HTMLStripFieldUpdateProcessorFactory - RegexReplaceProcessorFactory - FieldLengthUpdateProcessorFactory - ConcatFieldUpdateProcessorFactory - FirstFieldValueUpdateProcessorFactory - LastFieldValueUpdateProcessorFactory - MinFieldValueUpdateProcessorFactory - MaxFieldValueUpdateProcessorFactory - TruncateFieldUpdateProcessorFactory - IgnoreFieldUpdateProcessorFactory
    (hossman, janhoy)
  • SOLR-2857: Support XML,CSV,JSON, and javabin in a single RequestHandler and choose the correct ContentStreamLoader based on Content-Type header. This also deprecates the existing [Xml,JSON,CSV,Binary,Xslt]UpdateRequestHandler.
    (ryan)
  • SOLR-2898: Support grouped faceting. (Martijn van Groningen) Additional Work: - SOLR-3406: Extended grouped faceting support to facet.query and facet.range parameters. [SOLR-3406](https://issues.apache.org/jira/browse/SOLR-3406)
    (David Boychuck, Martijn van Groningen)
  • SOLR-2906: Added LFU cache options to Solr.
    (Shawn Heisey)
  • SOLR-2949: QueryElevationComponent is now supported with distributed search.
    (Mark Miller, yonik)
  • SOLR-2992: Add support for IndexWriter.prepareCommit() via prepareCommit=true on update URLs.
    (yonik)
  • SOLR-2993: Add WordBreakSolrSpellChecker to offer suggestions by combining adjacent query terms and/or breaking terms into multiple words. This spellchecker can be configured with a traditional checker (ie: DirectSolrSpellChecker). The results are combined and collations can contain a mix of corrections from both spellcheckers.
    (James Dyer)
  • SOLR-3069: Ability to add openSearcher=false to not open a searcher when doing a hard commit. commitWithin now only invokes a softCommit.
    (yonik)
  • SOLR-3120: Optional post filtering for spatial queries bbox and geofilt for LatLonType.
    (yonik)
  • SOLR-3134: Include shard info in distributed response when shards.info=true
    (Russell Black, ryan)
  • SOLR-3178: Optimistic locking. If a _version_ is provided with an update that does not match the version in the index, an HTTP 409 error (Conflict) will result.
    (Per Steffensen, yonik)
  • SOLR-3211: Allow parameter overrides in conjunction with "spellcheck.maxCollationTries". To do so, use parameters starting with "spellcheck.collateParam." For instance, to override the "mm" parameter, specify "spellcheck.collateParam.mm". This is helpful in cases where testing spellcheck collations for result counts should use different parameters from the main query
    (James Dyer)
  • SOLR-3221: Added the ability to directly configure aspects of the concurrency and thread-pooling used within distributed search in solr. This allows for finer grained controlled and can be tuned by end users to target their own specific requirements. This builds on the work of the HttpCommComponent and uses the same configuration block to configure the thread pool. The default configuration has the same behaviour as solr 3.5, favouring throughput over latency. More information can be found on the wiki
    (http://wiki.apache.org/solr/SolrConfigXml, Greg Bowyer)
  • SOLR-3238: Numerous small improvements to the Admin UI
    (steffkes)
  • SOLR-3255: OpenExchangeRates.Org Exchange Rate Provider for CurrencyField
    (janhoy)
  • SOLR-3272: Solr filter factory for MorfologikFilter (Polish lemmatisation).
    (Rafał Kuć, Steven Rowe, Uwe Schindler)
  • SOLR-3278: Negative boost support to the Extended Dismax Query Parser Boost Query (bq).
    (James Dyer)
  • SOLR-3304: Added Solr adapters for Lucene 4's new spatial module. With SpatialRecursivePrefixTreeFieldType ("location_rpt" in example schema), it is possible to index a variable number of points per document (and sort on them), index not just points but any Spatial4j supported shape such as polygons, and to query on these shapes too. Polygons requires adding JTS to the classpath.
    (David Smiley)
  • SOLR-3351: eDismax: ps2 and ps3 params
    (janhoy)
  • SOLR-3358: Logging events are captured and available from the /admin/logging request handler.
    (ryan)
  • SOLR-3363: Consolidated Exceptions in Analysis Factories so they only throw InitializationExceptions
    (Chris Male)
  • SOLR-3402: Analysis Factories are now configured with their Lucene Version throw setLuceneMatchVersion, rather than through the Map passed to init. Parsing and simple error checking for the Version is now done inside the code that creates the Analysis Factories.
    (Chris Male)
  • SOLR-3460: Add cloud-scripts directory and a zkcli.sh|bat tool for easy scripting and interaction with ZooKeeper.
    (Mark Miller)
  • SOLR-3488: Added a Collection management API for SolrCloud.
    (Tommaso Teofili, Sami Siren, yonik, Mark Miller)
  • SOLR-3495: New UpdateProcessors have been added to create default values for configured fields. These works similarly to the <field default="..."/> option in schema.xml, but are applied in the UpdateProcessorChain, so they may be used prior to other UpdateProcessors, or to generate a uniqueKey field value when using the DistributedUpdateProcessor (ie: SolrCloud) TimestampUpdateProcessorFactory UUIDUpdateProcessorFactory DefaultValueUpdateProcessorFactory
    (hossman)
  • SOLR-3508: Simplify JSON update format for deletes as well as allow version specification for optimistic locking. Examples: - {"delete":"myid"} - {"delete":["id1","id2","id3"]} - {"delete":{"id":"myid", "_version_":123456789}}
    (yonik)
  • SOLR-3542: Add WeightedFragListBuilder for FVH and set it to default fragListBuilder in example solrconfig.xml.
    (Sebastian Lutze, koji)
  • SOLR-3559: Full deleteByQuery support with SolrCloud distributed indexing. All replicas of a shard will be consistent, even if updates arrive in a different order on different replicas.
    (yonik)
  • SOLR-3562: Add options to remove instance dir or data dir on core unload.
    (Mark Miller, Per Steffensen)
  • SOLR-3597: seems like a lot of wasted whitespace at the top of the admin screens
    (steffkes)
  • SOLR-3634: CoreContainer and CoreAdminHandler will now remember and report back information about failures to initialize SolrCores. These failures will be accessible from the web UI and CoreAdminHandler STATUS command until they are "reset" by creating/renaming a SolrCore with the same name. [SOLR-3635](https://issues.apache.org/jira/browse/SOLR-3635)
    (hossman, steffkes)
  • SOLR-3670: New CountFieldValuesUpdateProcessorFactory makes it easy to index the number of values in another field for later use at query time.
    (hossman)
  • SOLR-3672: SimplePostTool: Improvements for posting files Support for auto mode, recursive and wildcards
    (janhoy)
  • SOLR-3821: Added 'df' to the UI Query form
    (steffkes)
  • SOLR-3822: Added hover titles to the edismax params on the UI Query form
    (steffkes)
  • SOLR-3825: Added optional capability to log what ids are in a response
    (Scott Stults, gsingers)
  • SOLR-571: The autowarmCount for LRUCaches (LRUCache and FastLRUCache) now supports "percentages" which get evaluated relative the current size of the cache when warming happens.
    (Tomás Fernández Löbbe, hossman)
  • SOLR-705: Optionally return shard info with each document in distributed search. Use fl=id,[shard] to return the shard url.
    (ryan)
  • SOLR-792: Adding PivotFacetComponent for Hierarchical faceting
    (ehatcher, Jeremy Hinegardner, Thibaut Lassalle, ryan)
• Changed   (11)
  • SOLR-1875: Per-segment field faceting for single valued string fields. Enable with facet.method=fcs, control the number of threads used with the "threads" local param on the facet.field param. This algorithm will only be faster in the presence of rapid index changes.
    (yonik)
  • SOLR-1904: When facet.enum.cache.minDf > 0 and the base doc set is a SortedIntSet, convert to HashDocSet for better performance.
    (yonik)
  • SOLR-2092: Speed up single-valued and multi-valued "fc" faceting. Typical improvement is 5%, but can be much greater (up to 10x faster) when facet.offset is very large (deep paging).
    (yonik)
  • SOLR-2193: The default Solr update handler has been improved so that it uses fewer locks, keeps the IndexWriter open rather than closing it on each commit (ie commits no longer wait for background merges to complete), works with SolrCore to provide faster 'soft' commits, and has an improved API that requires less instanceof special casing. (Mark Miller, Robert Muir) Additional Work: - SOLR-2697: commit and autocommit operations don't reset DirectUpdateHandler2.numDocsPending stats attribute. [SOLR-2565](https://issues.apache.org/jira/browse/SOLR-2565) [SOLR-2697](https://issues.apache.org/jira/browse/SOLR-2697)
    (Alexey Serba, Mark Miller)
  • SOLR-2950: The QueryElevationComponent now avoids using the FieldCache and looking up every document id
    (gsingers, yonik)
  • SOLR-3708: Add hashCode to ClusterState so that structures built based on the ClusterState can be easily cached.
    (Mark Miller)
  • SOLR-3709: Cache the url list created from the ClusterState in CloudSolrServer on each request.
    (Mark Miller)
  • SOLR-3710: Change CloudSolrServer so that update requests are only sent to leaders by default.
    (Mark Miller)
  • SOLR-3715: improve concurrency of the transaction log by removing synchronization around log record serialization.
    (yonik)
  • SOLR-3807: Currently during recovery we pause for a number of seconds after waiting for the leader to see a recovering state so that any previous updates will have finished before our commit on the leader - we don't need this wait for peersync.
    (Mark Miller)
  • SOLR-3837: When a leader is elected and asks replicas to sync back to him and that fails, we should ask those nodes to recovery asynchronously rather than synchronously.
    (Mark Miller)
• Fixed   (121)
  • LUCENE-4075: Cleaner path usage in TestXPathEntityProcessor

    (gsingers)
  • SOLR-1781: Replication index directories not always cleaned up.
    (Markus Jelsma, Terje Sten Bjerkseth, Mark Miller)
  • SOLR-1824: IndexSchema will now fail to initialize if there is a problem initializing one of the fields or field types.
    (hossman)
  • SOLR-1908: Fixed SignatureUpdateProcessor to fail to initialize on invalid config. Specifically: a signatureField that does not exist, or overwriteDupes=true with a signatureField that is not indexed.
    (hossman)
  • SOLR-1928: TermsComponent didn't correctly break ties for non-text fields sorted by count.
    (yonik)
  • SOLR-1958: When using the MailEntityProcessor, import would fail if fetchMailsSince was not specified.
    (Max Lynch)
  • SOLR-1962: SolrCore#initIndex should not use a mix of indexPath and newIndexPath
    (Mark Miller)
  • SOLR-2107: MoreLikeThisHandler doesn't work with alternate qparsers.
    (yonik)
  • SOLR-2108: Fixed false positives when using wildcard queries on fields with reversed wildcard support. For example, a query of *zemog* would match documents that contain 'gomez'.
    (Landon Kuhn)
  • SOLR-2193: SolrCores now properly share IndexWriters across SolrCore reloads. (Mark Miller, Robert Muir) Additional Work: - SOLR-2705: On reload, IndexWriterProvider holds onto the initial SolrCore it was created with.

    (Yonik Seeley, Hossman, Erick Erickson. Marc Tinnemeyer caught the bug)
  • SOLR-2848: Removed 'instanceof AbstractLuceneSpellChecker' hacks from distributed spellchecking code, and added a merge() method to SolrSpellChecker instead. Previously if you extended SolrSpellChecker your spellchecker would not work in distributed fashion.
    (James Dyer)
  • SOLR-2854: Now load URL content stream data (via stream.url) when called for during request handling, rather than loading URL content streams automatically regardless of use.
    (David Smiley, Ryan McKinley)

    (hossman)
  • SOLR-3569: Fixed debug output on distributed requests when there are no results found.
    (David Bowen, hossman)
  • SOLR-3582: Our ZooKeeper watchers respond to session events as if they are change events, creating undesirable side effects.
    (Trym R. Møller, Mark Miller)
  • SOLR-3587: After reloading a SolrCore, the original Analyzer is still used rather than a new one.
    (Alexey Serba, yonik, rmuir, Mark Miller)
  • SOLR-3595: CurrencyField now generates an appropriate error on schema init if it is configured as multiValued - this has never been properly supported, but previously failed silently in odd ways.
    (hossman)
  • SOLR-3610: After reloading a core, indexing would fail on any newly added fields to the schema.
    (Brent Mills, rmuir)

  • SOLR-3649: Fixed bug in JavabinLoader that caused deleteById(List<String> ids) to not work in SolrJ
    (siren)
  • SOLR-3652: Fixed range faceting to error instead of looping infinitely when 'gap' is zero -- or effectively zero due to floating point arithmetic underflow.
    (hossman)
  • SOLR-3656: A core reload now always uses the same dataDir.
    (Mark Miller, yonik)
  • SOLR-3658: Adding thousands of docs with one UpdateProcessorChain instance can briefly create spikes of threads in the thousands.
    (yonik, Mark Miller)
  • SOLR-3660: Velocity: Link to admin page broken
    (janhoy)
  • SOLR-3662: Core reload bugs: a reload always obtained a non-NRT searcher, which could go back in time with respect to the previous core's NRT searcher. Versioning did not work correctly across a core reload, and update handler synchronization was changed to synchronize on core state since more than on update handler can coexist for a single index during a reload.
    (yonik)
  • SOLR-3663: There are a couple of bugs in the sync process when a leader goes down and a new leader is elected.
    (Mark Miller)

  • SOLR-3725: Fixed package-local-src-tgz target to not bring in unnecessary jars and binary contents.
    (Michael Dodsworth, rmuir)

    (Ahmet Arslan, hossman)
  • SOLR-3770: Overseer may lose updates to cluster state

  • SOLR-3791: CachedSqlEntityProcessor would throw a NullPointerException when a query returns a row with a NULL key.
    (Steffen Moelter, James Dyer)
  • SOLR-3793: UnInvertedField faceting cached big terms in the filter cache that ignored deletions, leading to duplicate documents in search later when a filter of the same term was specified.

    (Mark Miller)
  • SOLR-3813: When a new leader syncs, we need to ask all shards to sync back, not just those that are active.
    (Mark Miller)
  • SOLR-3823: Fix 'bq' parsing in edismax. Please note that this required reverting the negative boost support added by SOLR-3278 [SOLR-3278](https://issues.apache.org/jira/browse/SOLR-3278)
    (hossman)
  • SOLR-3827: Fix shareSchema=true in solr.xml
    (Tomás Fernández Löbbe, hossman)
  • SOLR-3828: Fixed QueryElevationComponent so that using 'markExcludes' does not modify the result set or ranking of 'excluded' documents relative to not using elevation at all.
    (Alexey Serba, hossman)
  • SOLR-3831: Atomic updates do not distribute correctly to other nodes.
    (Jim Musil, Mark Miller)
  • SOLR-3833: When a election is started because a leader went down, the new leader candidate should decline if the last state they published was not active.
    (yonik, Mark Miller)
  • SOLR-3834: A new leader on cluster startup should also run the leader sync process in case there was a bad cluster shutdown.
    (Mark Miller)

    (Mark Miller)
  • SOLR-3836: When doing peer sync, we should only count sync attempts that cannot reach the given host as success when the candidate leader is syncing with the replicas - not when replicas are syncing to the leader.

    (rmuir)
  • LUCENE-3232: Moved MutableValue classes to new 'common' module.
    (Chris Male)
  • LUCENE-3286: 'luke' ant target has been disabled due to incompatibilities with XML queryparser location

    (Uri Boness, Chris Male)
  • SOLR-1258: PingRequestHandler is now directly configured with a "healthcheckFile" instead of looking for the legacy <admin><healthcheck/></admin> syntax. Filenames specified as relative paths have been fixed so that they are resolved against the data dir instead of the CWD of the java process.
    (hossman)
  • SOLR-1770: Move the default core instance directory into a collection1 folder.
    (Mark Miller)
  • SOLR-1825: SolrQuery.addFacetQuery now enables facets automatically, like addFacetField

    (hossman)
  • SOLR-2027: FacetField.getValues() now returns an empty list if there are no values, instead of null
    (Chris Male)
  • SOLR-2105: Remove support for deprecated "update.processor" (since 3.2), in favor of "update.chain"
    (janhoy)
  • SOLR-2115: DIH no longer requires the "config" parameter to be specified in solrconfig.xml. Instead, the configuration is loaded and parsed with every import. This allows the use of a different configuration with each import, and makes correcting configuration errors simpler. Also, the configuration itself can be passed using the "dataConfig" parameter rather than using a file (this previously worked in debug mode only). When configuration errors are encountered, the error message is returned in XML format.

  • SOLR-3488: Added a Collection management API for SolrCloud.
    (Tommaso Teofili, Sami Siren, yonik, Mark Miller)
  • SOLR-3559: Full deleteByQuery support with SolrCloud distributed indexing. All replicas of a shard will be consistent, even if updates arrive in a different order on different replicas.
    (yonik)
  • SOLR-3562: Add options to remove instance dir or data dir on core unload.
    (Mark Miller, Per Steffensen)
  • SOLR-3634: CoreContainer and CoreAdminHandler will now remember and report back information about failures to initialize SolrCores. These failures will be accessible from the web UI and CoreAdminHandler STATUS command until they are "reset" by creating/renaming a SolrCore with the same name. [SOLR-3635](https://issues.apache.org/jira/browse/SOLR-3635)
    (hossman, steffkes)
  • SOLR-3672: SimplePostTool: Improvements for posting files Support for auto mode, recursive and wildcards
    (janhoy)
• Changed   (3)
  • SOLR-3708: Add hashCode to ClusterState so that structures built based on the ClusterState can be easily cached.
    (Mark Miller)
  • SOLR-3709: Cache the url list created from the ClusterState in CloudSolrServer on each request.
    (Mark Miller, yonik)
  • SOLR-3710: Change CloudSolrServer so that update requests are only sent to leaders by default.
    (Mark Miller)
• Fixed   (22)
  • LUCENE-4185: Fix a bug where CharFilters were wrongly being applied twice.
    (Michael Froh, rmuir)
  • SOLR-1781: Replication index directories not always cleaned up.
    (Markus Jelsma, Terje Sten Bjerkseth, Mark Miller)
  • SOLR-3377: edismax fails to correctly parse a fielded query wrapped by parens. This regression was introduced in 3.6.
    (Bernd Fehling, Jan Høydahl, yonik)
  • SOLR-3428: SolrCmdDistributor flushAdds/flushDeletes can cause repeated adds/deletes to be sent
    (Mark Miller, Per Steffensen)
  • SOLR-3467: ExtendedDismax escaping is missing several reserved characters
    (Michael Dodsworth, janhoy)
  • SOLR-3582: Our ZooKeeper watchers respond to session events as if they are change events, creating undesirable side effects.
    (Trym R. Møller, Mark Miller)
  • SOLR-3587: After reloading a SolrCore, the original Analyzer is still used rather than a new one.
    (Alexey Serba, yonik, rmuir, Mark Miller)
  • SOLR-3610: After reloading a core, indexing would fail on any newly added fields to the schema.
    (Brent Mills, rmuir)
  • SOLR-3621: Fix rare concurrency issue when opening a new IndexWriter for replication or rollback.
    (Mark Miller)
  • SOLR-3623: Fixed inconsistent treatment of third-party dependencies for solr contribs analysis-extras & uima
    (hossman)
  • SOLR-3629: Typo in solr.xml persistence when overriding the solrconfig.xml file name using the "config" attribute prevented the override file from being used.
    (Ryan Zezeski, hossman)
  • SOLR-3639: Update ZooKeeper to 3.3.6 for a variety of bug fixes.
    (Mark Miller)
  • SOLR-3642: Correct broken check for multivalued fields in stats.facet
    (Yandong Yao, hossman)
  • SOLR-3647: DistributedQueue should use our Solr zk client rather than the std zk client. ZooKeeper expiration can be permanent otherwise.
    (Mark Miller)
  • SOLR-3648: Fixed VelocityResponseWriter template loading in SolrCloud mode. For the example configuration, this means /browse now works with SolrCloud.
    (janhoy, ehatcher)
  • SOLR-3652: Fixed range faceting to error instead of looping infinitely when 'gap' is zero -- or effectively zero due to floating point arithmetic underflow.
    (hossman)
  • SOLR-3656: A core reload now always uses the same dataDir.
    (Mark Miller, yonik)
  • SOLR-3658: Adding thousands of docs with one UpdateProcessorChain instance can briefly create spikes of threads in the thousands.
    (yonik, Mark Miller)
  • SOLR-3660: Velocity: Link to admin page broken
    (janhoy)
  • SOLR-3662: Core reload bugs: a reload always obtained a non-NRT searcher, which could go back in time with respect to the previous core's NRT searcher. Versioning did not work correctly across a core reload, and update handler synchronization was changed to synchronize on core state since more than on update handler can coexist for a single index during a reload.
    (yonik)
  • SOLR-3663: There are a couple of bugs in the sync process when a leader goes down and a new leader is elected.
    (Mark Miller)
  • SOLR-3677: Fixed misleading error message in web ui to distinguish between no SolrCores loaded vs. no /admin/ handler available.
    (hossman, steffkes)
• Other   (14)
  • SOLR-1770: Move the default core instance directory into a collection1 folder.
    (Mark Miller)
  • SOLR-2115: DIH no longer requires the "config" parameter to be specified in solrconfig.xml. Instead, the configuration is loaded and parsed with every import. This allows the use of a different configuration with each import, and makes correcting configuration errors simpler. Also, the configuration itself can be passed using the "dataConfig" parameter rather than using a file (this previously worked in debug mode only). When configuration errors are encountered, the error message is returned in XML format.
    (James Dyer)
  • SOLR-3215: Clone SolrInputDocument when distrib indexing so that update processors after the distrib update process do not process the document twice.
    (Mark Miller)
  • SOLR-3355: Add shard and collection to SolrCore statistics.
    (Michael Garski, Mark Miller)
  • SOLR-3439: Make SolrCell easier to use out of the box. Also improves "/browse" to display rich-text documents correctly, along with facets for author and content_type. With the new "content" field, highlighting of body is supported. See also SOLR-3672 for easier posting of a whole directory structure. [SOLR-3672](https://issues.apache.org/jira/browse/SOLR-3672)
    (Jack Krupansky, janhoy)
  • SOLR-3524: Make discarding punctuation configurable in JapaneseTokenizerFactory. The default is to discard punctuation, but this is overridable as an expert option.
    (Kazuaki Hiraga, Jun Ohtani, Christian Moen)
  • SOLR-3563: Unloading all cores in a SolrCloud collection will now cause the removal of that collection's meta data from ZooKeeper.
    (Mark Miller, Per Steffensen)
  • SOLR-3575: solr.xml should default to persist=true
    (Mark Miller)
  • SOLR-3579: SolrCloud view should default to the graph view rather than tree view.
    (steffkes, Mark Miller)
  • SOLR-3599: Add zkClientTimeout to solr.xml so that it's obvious how to change it and so that you can change it with a system property.
    (Mark Miller)
  • SOLR-3600: Raise the default zkClientTimeout from 10 seconds to 15 seconds.
    (Mark Miller)
  • SOLR-3609: Change Solr's expanded webapp directory to be at a consistent path called solr-webapp rather than a temporary directory.
    (Mark Miller)
  • SOLR-3682: Fail to parse schema.xml if uniqueKeyField is multivalued
    (hossman)
  • SOLR-3683: Improved error handling if an <analyzer> contains both an explicit class attribute, as well as nested factories.
    (hossman)

Release 4.0.0-ALPHA [2012-07-03]

• Added   (60)
  • SOLR-1032: CSV handler now supports "literal.field_name=value" parameters.
    (Simon Rosenthal, ehatcher)
  • SOLR-1298: Return FunctionQuery as pseudo field. The solr 'fl' param now supports functions. For example: fl=id,sum(x,y) -- NOTE: only functions with fast random access are recommended.
    (yonik, ryan)
  • SOLR-139: Updateable documents. JSON Example: {"id":"mydoc", "f1":{"set":10}, "f2":{"add":20}} will result in field "f1" being set to 10, "f2" having an additional value of 20 added, and all other existing fields unchanged. All source fields must be stored for this feature to work correctly.
    (Ryan McKinley, Erik Hatcher, yonik)
  • SOLR-1535: PreAnalyzedField type provides a functionality to index (and optionally store) field content that was already processed and split into tokens using some external processing chain. Serialization format is pluggable, and defaults to JSON.
    (ab)
  • SOLR-1566: Transforming documents in the ResponseWriters. This will allow for more complex results in responses and open the door for function queries as results. (ryan with patches from grant, noble, cmale, yonik, Jan Høydahl, Arul Kalaipandian, Luca Cavanna, hossman) - SOLR-2037: Thanks to SOLR-1566, documents boosted by the QueryElevationComponent can be marked as boosted. [SOLR-2037](https://issues.apache.org/jira/browse/SOLR-2037)
    (gsingers, ryan, yonik)
  • SOLR-1665: Add debug component options for timings, results and query info only
    (gsingers, hossman, yonik)
  • SOLR-1873: SolrCloud - added shared/central config and core/shard management via zookeeper, built-in load balancing, and distributed indexing. (Jamie Johnson, Sami Siren, Ted Dunning, yonik, Mark Miller) Additional Work: - SOLR-2324: SolrCloud solr.xml parameters are not persisted by CoreContainer. (Massimo Schiavon, Mark Miller) - SOLR-2287: Allow users to query by multiple, compatible collections with SolrCloud. (Soheb Mahmood, Alex Cowell, Mark Miller) - SOLR-2622: ShowFileRequestHandler does not work in SolrCloud mode.

(Bruno Dumon, Sami Siren, Mark Miller) - SOLR-3080: Remove shard info from zookeeper when SolrCore is explicitly unloaded. (yonik, Mark Miller, siren) - SOLR-3437: Recovery issues a spurious commit to the cluster. (Trym R. Møller via Mark Miller) - SOLR-2822: Skip update processors already run on other nodes [SOLR-2358](https://issues.apache.org/jira/browse/SOLR-2358) [SOLR-2324](https://issues.apache.org/jira/browse/SOLR-2324) [SOLR-2287](https://issues.apache.org/jira/browse/SOLR-2287) [SOLR-2622](https://issues.apache.org/jira/browse/SOLR-2622) [SOLR-3108](https://issues.apache.org/jira/browse/SOLR-3108) [SOLR-3080](https://issues.apache.org/jira/browse/SOLR-3080) [SOLR-3437](https://issues.apache.org/jira/browse/SOLR-3437) [SOLR-2822](https://issues.apache.org/jira/browse/SOLR-2822)
    (hossman)
  • SOLR-1932: New relevancy function queries: termfreq, tf, docfreq, idf norm, maxdoc, numdocs.
    (yonik)
  • SOLR-1942: Added the ability to select postings format per fieldType in schema.xml as well as support custom Codecs in solrconfig.xml.
    (simonw, rmuir)
  • SOLR-2058: Edismax query parser to allow "phrase slop" to be specified per-field on the pf/pf2/pf3 parameters using optional "FieldName~slop^boost" syntax. The prior "FieldName^boost" syntax is still accepted. In such cases the value on the "ps" parameter serves as the default slop.
    (Ron Mayer, James Dyer)
  • SOLR-2112: Solrj API now supports streaming results.
    (ryan)
  • SOLR-2134: Trie* fields should support sortMissingLast=true, and deprecate Sortable* Field Types
    (Ryan McKinley, Mike McCandless, Uwe Schindler, Erick Erickson)
  • SOLR-2136: Boolean type added to function queries, along with new functions exists(), if(), and(), or(), xor(), not(), def(), and true and false constants.
    (yonik)
  • SOLR-2193: You may now specify a 'soft' commit when committing. This will use Lucene's NRT feature to avoid guaranteeing documents are on stable storage in exchange for faster reopen times. There is also a new 'soft' autocommit tracker that can be configured. [SOLR-2565](https://issues.apache.org/jira/browse/SOLR-2565)
    (Mark Miller, Robert Muir)
  • SOLR-2272: Pseudo-join queries / filters. Examples: - To restrict to the set of parents with at least one blue-eyed child: fq={!join from=parent to=name}eyes:blue - To restrict to the set of children with at least one blue-eyed parent: fq={!join from=name to=parent}eyes:blue
    (yonik)
  • SOLR-2335: New 'field("...")' function syntax for referring to complex field names (containing whitespace or special characters) in functions.
  • SOLR-2338: Add support for using <similarity/> in a schema's fieldType, for customizing scoring on a per-field basis.
    (hossman, yonik, rmuir)
  • SOLR-2383: /browse improvements: generalize range and date facet display
    (Jan Høydahl, yonik)
  • SOLR-2396: Add CollationField, which is much more efficient than the Solr 3.x CollationKeyFilterFactory, and also supports Locale-sensitive range queries.
    (rmuir)
  • SOLR-2396: Add ICUCollationField to contrib/analysis-extras, which is much more efficient than the Solr 3.x ICUCollationKeyFilterFactory, and also supports Locale-sensitive range queries.
    (rmuir)
  • SOLR-2399: Updated Solr Admin interface. New look and feel with per core administration and many new options.
    (Stefan Matheis, ryan)
  • SOLR-2417: Add explain info directly to return documents using ?fl=id,[explain]
    (ryan)
  • SOLR-2438: added MultiTermAwareComponent to the various classes to allow automatic lowercasing for multiterm queries (wildcards, regex, prefix, range, etc). You can now optionally specify a "multiterm" analyzer in our schema.xml, but Solr should "do the right thing" if you don't specify <analyzer type="multiterm">
    (Pete Sturge Erick Erickson, Mentoring from Seeley, Muir)
  • SOLR-2459: Expose LogLevel selection with a RequestHandler rather then servlet
    (Stefan Matheis, Upayavira, ryan)
  • SOLR-2481: Add support for commitWithin in DataImportHandler
    (Sami Siren, yonik)
  • SOLR-2491: Add support for using spellcheck collation in conjunction with grouping. Note that the number of hits returned for collations is the number of ungrouped hits.
    (James Dyer, rmuir)
  • SOLR-2533: Converted ValueSource.ValueSourceSortField over to new rewriteable Lucene SortFields. ValueSourceSortField instances must be rewritten before they can be used. This is done by SolrIndexSearcher when necessary.
    (Chris Male)
  • LUCENE-2507: Added DirectSolrSpellChecker, which uses Lucene's DirectSpellChecker to retrieve correction candidates directly from the term dictionary using levenshtein automata. [SOLR-2571](https://issues.apache.org/jira/browse/SOLR-2571) [SOLR-2576](https://issues.apache.org/jira/browse/SOLR-2576)
    (James Dyer, rmuir)
  • SOLR-2585: Context-Sensitive Spelling Suggestions & Collations. This adds support for the "spellcheck.alternativeTermCount" & "spellcheck.maxResultsForSuggest" parameters, letting users receive suggestions even when all the queried terms exist in the dictionary. This differs from "spellcheck.onlyMorePopular" in that the suggestions need not consist entirely of terms with a greater document frequency than the queried terms.
    (James Dyer)
  • SOLR-2599: CloneFieldUpdateProcessorFactory provides similar functionality to schema.xml's <copyField/> declaration but as an update processor that can be combined with other processors in any order.
    (Jan Høydahl & hossman)
  • SOLR-2656: realtime-get, efficiently retrieves the latest stored fields for specified documents, even if they are not yet searchable
    (i.e. without reopening a searcher, yonik)
  • SOLR-2690: New support for a "TZ" request param which overrides the TimeZone used when rounding Dates in DateMath expressions for the entire request (all date range queries and date faceting is affected). The default TZ is still UTC.
    (David Schlotfeldt, hossman)
  • SOLR-2703: Added support for Lucene's "surround" query parser.
    (Simon Rosenthal, ehatcher)
  • SOLR-2754: Added factories for several ranking algorithms: - BM25SimilarityFactory: Okapi BM25 - DFRSimilarityFactory: Divergence from Randomness models - IBSimilarityFactory: Information-based models - LMDirichletSimilarity: LM with Dirichlet smoothing - LMJelinekMercerSimilarity: LM with Jelinek-Mercer smoothing
    (David Mark Nemeskey, Robert Muir)
  • SOLR-2802: New FieldMutatingUpdateProcessor and Factory to simplify the development of UpdateProcessors that modify field values of documents as they are indexed. Also includes several useful new implementations: - RemoveBlankFieldUpdateProcessorFactory - TrimFieldUpdateProcessorFactory - HTMLStripFieldUpdateProcessorFactory - RegexReplaceProcessorFactory - FieldLengthUpdateProcessorFactory - ConcatFieldUpdateProcessorFactory - FirstFieldValueUpdateProcessorFactory - LastFieldValueUpdateProcessorFactory - MinFieldValueUpdateProcessorFactory - MaxFieldValueUpdateProcessorFactory - TruncateFieldUpdateProcessorFactory - IgnoreFieldUpdateProcessorFactory
    (hossman, janhoy)
  • SOLR-2857: Support XML,CSV,JSON, and javabin in a single RequestHandler and choose the correct ContentStreamLoader based on Content-Type header. This also deprecates the existing [Xml,JSON,CSV,Binary,Xslt]UpdateRequestHandler.
    (ryan)
  • SOLR-2898: Support grouped faceting. (Martijn van Groningen) Additional Work: - SOLR-3406: Extended grouped faceting support to facet.query and facet.range parameters. [SOLR-3406](https://issues.apache.org/jira/browse/SOLR-3406)
    (David Boychuck, Martijn van Groningen)
  • SOLR-2906: Added LFU cache options to Solr.
    (Shawn Heisey, Erick Erickson)
  • SOLR-2949: QueryElevationComponent is now supported with distributed search.
    (Mark Miller, yonik)
  • SOLR-2992: Add support for IndexWriter.prepareCommit() via prepareCommit=true on update URLs.
    (yonik)
  • SOLR-2993: Add WordBreakSolrSpellChecker to offer suggestions by combining adjacent query terms and/or breaking terms into multiple words. This spellchecker can be configured with a traditional checker (ie: DirectSolrSpellChecker). The results are combined and collations can contain a mix of corrections from both spellcheckers.
    (James Dyer)
  • SOLR-3069: Ability to add openSearcher=false to not open a searcher when doing a hard commit. commitWithin now only invokes a softCommit.
    (yonik)
  • SOLR-3120: Optional post filtering for spatial queries bbox and geofilt for LatLonType.
    (yonik)
  • SOLR-3134: Include shard info in distributed response when shards.info=true
    (Russell Black, ryan)
  • SOLR-3178: Optimistic locking. If a _version_ is provided with an update that does not match the version in the index, an HTTP 409 error (Conflict) will result.
    (Per Steffensen, yonik)
  • SOLR-3211: Allow parameter overrides in conjunction with "spellcheck.maxCollationTries". To do so, use parameters starting with "spellcheck.collateParam." For instance, to override the "mm" parameter, specify "spellcheck.collateParam.mm". This is helpful in cases where testing spellcheck collations for result counts should use different parameters from the main query
    (James Dyer)
  • SOLR-3221: Added the ability to directly configure aspects of the concurrency and thread-pooling used within distributed search in solr. This allows for finer grained controlled and can be tuned by end users to target their own specific requirements. This builds on the work of the HttpCommComponent and uses the same configuration block to configure the thread pool. The default configuration has the same behaviour as solr 3.5, favouring throughput over latency. More information can be found on the wiki
    (http://wiki.apache.org/solr/SolrConfigXml, Greg Bowyer)
  • SOLR-3255: OpenExchangeRates.Org Exchange Rate Provider for CurrencyField
    (janhoy)
  • SOLR-3272: Solr filter factory for MorfologikFilter (Polish lemmatisation).
    (Rafał Kuć, Dawid Weiss, Steven Rowe, Uwe Schindler)
  • SOLR-3278: Negative boost support to the Extended Dismax Query Parser Boost Query (bq).
    (James Dyer)
  • SOLR-3351: eDismax: ps2 and ps3 params
    (janhoy)
  • SOLR-3358: Logging events are captured and available from the /admin/logging request handler.
    (ryan)
  • SOLR-3363: Consolidated Exceptions in Analysis Factories so they only throw InitializationExceptions
    (Chris Male)
  • SOLR-3402: Analysis Factories are now configured with their Lucene Version throw setLuceneMatchVersion, rather than through the Map passed to init. Parsing and simple error checking for the Version is now done inside the code that creates the Analysis Factories.
    (Chris Male)
  • SOLR-3495: New UpdateProcessors have been added to create default values for configured fields. These works similarly to the <field default="..."/> option in schema.xml, but are applied in the UpdateProcessorChain, so they may be used prior to other UpdateProcessors, or to generate a uniqueKey field value when using the DistributedUpdateProcessor (ie: SolrCloud) TimestampUpdateProcessorFactory UUIDUpdateProcessorFactory DefaultValueUpdateProcessorFactory
    (hossman)
  • SOLR-3508: Simplify JSON update format for deletes as well as allow version specification for optimistic locking. Examples: - {"delete":"myid"} - {"delete":["id1","id2","id3"]} - {"delete":{"id":"myid", "_version_":123456789}}
    (yonik)
  • SOLR-3542: Add WeightedFragListBuilder for FVH and set it to default fragListBuilder in example solrconfig.xml.
    (Sebastian Lutze, koji)
  • SOLR-571: The autowarmCount for LRUCaches (LRUCache and FastLRUCache) now supports "percentages" which get evaluated relative the current size of the cache when warming happens.
    (Tomás Fernández Löbbe, hossman)
  • SOLR-705: Optionally return shard info with each document in distributed search. Use fl=id,[shard] to return the shard url.
    (ryan)
  • SOLR-792: Adding PivotFacetComponent for Hierarchical faceting
    (ehatcher, Jeremy Hinegardner, Thibaut Lassalle, ryan)
• Changed   (5)
  • SOLR-1875: Per-segment field faceting for single valued string fields. Enable with facet.method=fcs, control the number of threads used with the "threads" local param on the facet.field param. This algorithm will only be faster in the presence of rapid index changes.
    (yonik)
  • SOLR-1904: When facet.enum.cache.minDf > 0 and the base doc set is a SortedIntSet, convert to HashDocSet for better performance.
    (yonik)
  • SOLR-2092: Speed up single-valued and multi-valued "fc" faceting. Typical improvement is 5%, but can be much greater (up to 10x faster) when facet.offset is very large (deep paging).
    (yonik)
  • SOLR-2193: The default Solr update handler has been improved so that it uses fewer locks, keeps the IndexWriter open rather than closing it on each commit (ie commits no longer wait for background merges to complete), works with SolrCore to provide faster 'soft' commits, and has an improved API that requires less instanceof special casing. (Mark Miller, Robert Muir) Additional Work: - SOLR-2697: commit and autocommit operations don't reset DirectUpdateHandler2.numDocsPending stats attribute. [SOLR-2565](https://issues.apache.org/jira/browse/SOLR-2565) [SOLR-2697](https://issues.apache.org/jira/browse/SOLR-2697)

• Fixed   (41)
  • LUCENE-4075: Cleaner path usage in TestXPathEntityProcessor
    (Greg Bowyer, hossman)
  • SOLR-1520: QueryElevationComponent now supports non-string ids
    (gsingers)
  • SOLR-1730: Made it clearer when a core failed to load as well as better logging when the QueryElevationComponent fails to properly initialize
    (gsingers)
  • SOLR-1824: IndexSchema will now fail to initialize if there is a problem initializing one of the fields or field types.
    (hossman)
  • SOLR-1908: Fixed SignatureUpdateProcessor to fail to initialize on invalid config. Specifically: a signatureField that does not exist, or overwriteDupes=true with a signatureField that is not indexed.
    (hossman)
  • SOLR-1928: TermsComponent didn't correctly break ties for non-text fields sorted by count.
    (yonik)
  • SOLR-1958: When using the MailEntityProcessor, import would fail if fetchMailsSince was not specified.
    (Max Lynch, James Dyer)
  • SOLR-1962: SolrCore#initIndex should not use a mix of indexPath and newIndexPath
    (Mark Miller)
  • SOLR-2107: MoreLikeThisHandler doesn't work with alternate qparsers.
    (yonik)
  • SOLR-2108: Fixed false positives when using wildcard queries on fields with reversed wildcard support. For example, a query of *zemog* would match documents that contain 'gomez'.
    (Landon Kuhn, Robert Muir)
  • SOLR-2193: SolrCores now properly share IndexWriters across SolrCore reloads. (Mark Miller, Robert Muir) Additional Work: - SOLR-2705: On reload, IndexWriterProvider holds onto the initial SolrCore it was created with. [SOLR-2565](https://issues.apache.org/jira/browse/SOLR-2565) [SOLR-2651](https://issues.apache.org/jira/browse/SOLR-2651) [SOLR-2705](https://issues.apache.org/jira/browse/SOLR-2705)
    (Yury Kats, Mark Miller)
  • SOLR-2275: fix DisMax 'mm' parsing to be tolerant of whitespace
    (Erick Erickson, hossman)
  • SOLR-2352: Fixed TermVectorComponent so that it will not fail if the fl param contains globs or pseudo-fields
    (hossman)
  • SOLR-2509: StringIndexOutOfBoundsException in the spellchecker collate when the term contains a hyphen.
    (Thomas Gambier caught the bug, Steffen Godskesen did the patch, Erick Erickson)
  • SOLR-2605: fixed tracking of the 'defaultCoreName' in CoreContainer so that CoreAdminHandler could return consistent information regardless of whether there is a a default core name or not.
    (steffkes, hossman)
  • SOLR-2654: Directorys used by a SolrCore are now closed when they are no longer used.
    (Mark Miller)
  • SOLR-2682: Remove addException() in SimpleFacet. FacetComponent no longer catches and embeds exceptions occurred during facet processing, it throws HTTP 400 or 500 exceptions instead.
    (koji)
  • SOLR-2741: Bugs in facet range display in trunk
    (janhoy)
  • SOLR-2762: FSTLookup could return duplicate results or one results less than requested.
    (David Smiley, Dawid Weiss)
  • SOLR-2829: Fix problem with false-positives due to incorrect equals methods.
    (Yonik Seeley, Hossman, Erick Erickson. Marc Tinnemeyer caught the bug)
  • SOLR-2848: Removed 'instanceof AbstractLuceneSpellChecker' hacks from distributed spellchecking code, and added a merge() method to SolrSpellChecker instead. Previously if you extended SolrSpellChecker your spellchecker would not work in distributed fashion.
    (James Dyer, rmuir)
  • SOLR-2854: Now load URL content stream data (via stream.url) when called for during request handling, rather than loading URL content streams automatically regardless of use.
    (David Smiley, Ryan McKinley, ehatcher)
  • SOLR-2923: IllegalArgumentException when using useFilterForSortedQuery on an empty index.
    (Adrien Grand, Mark Miller)

    (Peter Sturge, yonik, Simon Willnauer)
  • SOLR-1843: A new "rootName" attribute is now available when configuring <jmx/> in solrconfig.xml. If this attribute is set, Solr will use it as the root name for all MBeans Solr exposes via JMX. The default root name is "solr" followed by the core name.

    (Greg Fodor & Andrew Morrison, janhoy, rmuir, Uwe Schindler)
  • SOLR-2346: Add a chance to set content encoding explicitly via content type of stream for extracting request handler. This is convenient when Tika's auto detector cannot detect encoding, especially the text file is too short to detect encoding.
    (koji)
  • SOLR-2382: Added pluggable cache support to DIH so that any Entity can be made cache-able by adding the "cacheImpl" parameter. Include "SortedMapBackedCache" to provide in-memory caching (as previously this was the only option when using CachedSqlEntityProcessor). Users can provide their own implementations of DIHCache for other caching strategies. Deprecate CachedSqlEntityProcessor in favor of specifing "cacheImpl" with SqlEntityProcessor. Make SolrWriter implement DIHWriter and allow the possibility of pluggable Writers (DIH writing to something other than Solr).
    (James Dyer, Noble Paul)
  • SOLR-2438: added MultiTermAwareComponent to the various classes to allow automatic lowercasing for multiterm queries (wildcards, regex, prefix, range, etc). You can now optionally specify a "multiterm" analyzer in our schema.xml, but Solr should "do the right thing" if you don't specify <fieldType="multiterm">
    (Pete Sturge Erick Erickson, Mentoring from Seeley, Muir)

    (shalin)
  • SOLR-2906: Added LFU cache options to Solr.
    (Shawn Heisey, Erick Erickson)

    (rmuir)
  • SOLR-2919: Added support for localized range queries when the analysis chain uses CollationKeyFilter or ICUCollationKeyFilter.
    (Michael Sokolov, rmuir)

    (Luca Cavanna, Martijn van Groningen)
  • SOLR-3221: Added the ability to directly configure aspects of the concurrency and thread-pooling used within distributed search in solr. This allows for finer grained controlled and can be tuned by end users to target their own specific requirements. This builds on the work of the HttpCommComponent and uses the same configuration block to configure the thread pool. The default configuration has the same behaviour as solr 3.5, favouring throughput over latency. More information can be found on the wiki
    (http://wiki.apache.org/solr/SolrConfigXml, Greg Bowyer)
• Changed   (3)
  • SOLR-1931: Speedup for LukeRequestHandler and admin/schema browser. New parameter reportDocCount defaults to 'false'. Old behavior still possible by specifying this as 'true'
    (Erick Erickson)

    (Dawid Weiss, Robert Muir)
  • SOLR-3012: Move System.getProperty("type") in postData() to main() and add type argument so that the client applications of SimplePostTool can set content type via method argument.

    (Cody Young, Martijn van Groningen)
  • LUCENE-3690: Re-implemented HTMLStripCharFilter as a JFlex-generated scanner and moved it to lucene/contrib/analyzers/common/. See below for a list of bug fixes and other changes. To get the same behavior as HTMLStripCharFilter in Solr version 3.5 and earlier (including the bugs), use LegacyHTMLStripCharFilter, which is the previous implementation. Behavior changes from the previous version: - Known offset bugs are fixed. - The "Mark invalid" exceptions reported in SOLR-1283 are no longer triggered (the bug is still present in LegacyHTMLStripCharFilter). - The character entity "'" is now always properly decoded. - More cases of <script> tags are now properly stripped. - CDATA sections are now handled properly. - Valid tag name characters now include the supplementary Unicode characters from Unicode character classes [:ID_Start:] and [:ID_Continue:]. - Uppercase character entities """, "©", ">", "<", "®", and "&" are now recognized and handled as if they were in lowercase. - The REPLACEMENT CHARACTER U+FFFD is now used to replace numeric character entities for unpaired UTF-16 low and high surrogates (in the range [U+D800-U+DFFF]). - Properly paired numeric character entities for UTF-16 surrogates are now converted to the corresponding code units. - Opening tags with unbalanced quotation marks are now properly stripped. - Literal "<" and ">" characters in opening tags, regardless of whether they appear inside quotation marks, now inhibit recognition (and stripping) of the tags. The only exception to this is for values of event-handler attributes, e.g. "onClick", "onLoad", "onSelect". - A newline '\n' is substituted instead of a space for stripped HTML markup. - Nothing is substituted for opening and closing inline tags - they are simply removed. The list of inline tags is (case insensitively): <a>, <abbr>, <acronym>, <b>, <basefont>, <bdo>, <big>, <cite>, <code>, <dfn>, <em>, <font>, <i>, <img>, <input>, <kbd>, <label>, <q>, <s>, <samp>, <select>, <small>, <span>, <strike>, <strong>, <sub>, <sup>, <textarea>, <tt>, <u>, and <var>. - HTMLStripCharFilterFactory now handles HTMLStripCharFilter's "escapedTags" feature: opening and closing tags with the given names, including any attributes and their values, are left intact in the output.

  • SOLR-2429: Ability to add cache=false to queries and query filters to avoid using the filterCache or queryCache. A cost may also be specified and is used to order the evaluation of non-cached filters from least to greatest cost . For very expensive query filters (cost >= 100) if the query implements the PostFilter interface, it will be used to obtain a Collector that is checked only for documents that match the main query and all other filters. The "frange" query now implements the PostFilter interface.

    (David Smiley, yonik)
  • SOLR-2630: Added new XsltUpdateRequestHandler that works like XmlUpdateRequestHandler but allows to transform the POSTed XML document using XSLT. This allows to POST arbitrary XML documents to the update handler, as long as you also provide a XSL to transform them to a valid Solr input document.
    (Upayavira, Uwe Schindler)
  • SOLR-2637: Added support for group result parsing in SolrJ.
    (Tao Cheng, Martijn van Groningen)

    (Frank Wesemann, shalin)
  • SOLR-2662: When Solr is configured to have no queryResultCache, the "start" parameter was not honored and the documents returned were 0 through start+offset.
    (Markus Jelsma, yonik)

  • LUCENE-3406: Add ant target 'package-local-src-tgz' to Lucene and Solr to package sources from the local working copy.
    (Seung-Yeoul Yang, Steve Rowe)
  • SOLR-2452: Rewrote the Solr build system: - Integrated more fully with the Lucene build system: generalized the Lucene build system and eliminated duplication. - Converted all Solr contribs to the Lucene/Solr conventional src/ layout: java/, resources/, test/, and test-files/<contrib-name>. - Created a new Solr-internal module named "core" by moving the java/, test/, and test-files/ directories from solr/src/ to solr/core/src/. - Merged solr/src/webapp/src/ into solr/core/src/java/. - Eliminated solr/src/ by moving all its directories up one level; renamed solr/src/site/ to solr/site-src/ because solr/site/ already exists. - Merged solr/src/common/ into solr/solrj/src/java/. - Moved o.a.s.client.solrj.* and o.a.s.common.* tests from solr/src/test/ to solr/solrj/src/test/. - Made the solrj tests not depend on the solr core tests by moving some classes from solr/src/test/ to solr/test-framework/src/java/. - Each internal module (core/, solrj/, test-framework/, and webapp/) now has its own build.xml, from which it is possible to run module-specific targets. solr/build.xml delegates all build tasks (via <ant dir="internal-module-dir"> calls) to these modules' build.xml files.

  • SOLR-1331: -- Added a srcCore parameter to CoreAdminHandler's mergeindexes action to merge one or more cores' indexes to a target core
    (shalin)
  • SOLR-2378: A new, automaton-based, implementation of suggest (autocomplete) component, offering an order of magnitude smaller memory consumption compared to ternary trees and jaspell and very fast lookups at runtime.
    (Dawid Weiss)
  • SOLR-2400: Field- and DocumentAnalysisRequestHandler now provide a position history for each token, so you can follow the token through all analysis stages. The output contains a separate int[] attribute containing all positions from previous Tokenizers/TokenFilters (called "positionHistory").
    (Uwe Schindler)

    (James Dyer, rmuir)
  • SOLR-2519: Improve text_* fieldTypes in example schema.xml: improve cross-language defaults for text_general; break out separate English-specific fieldTypes

  • SOLR-2581: UIMAToSolrMapper wrongly instantiates Type with reflection.
    (Tommaso Teofili, koji)
• Other   (5)
  • LUCENE-3204: The maven-ant-tasks jar is now included in the source tree; users of the generate-maven-artifacts target no longer have to manually place this jar in the Ant classpath. NOTE: when Ant looks for the maven-ant-tasks jar, it looks first in its pre-existing classpath, so any copies it finds will be used instead of the copy included in the Lucene/Solr source tree. For this reason, it is recommeded to remove any copies of the maven-ant-tasks jar in the Ant classpath, e.g. under ~/.ant/lib/ or under the Ant installation's lib/ directory.
    (Steve Rowe)
  • SOLR-2571: Add a commented out example of the spellchecker's thresholdTokenFrequency parameter to the example solrconfig.xml, and also add a unit test for this feature.

    (hossman, yonik)
  • SOLR-2448: Search results clustering updates: bisecting k-means clustering algorithm added, loading of Carrot2 stop words from <solr.home>/conf/carrot2 (SOLR-2449), using Solr's stopwords.txt for clustering (SOLR-2450), output of cluster scores (SOLR-2505) [SOLR-2449](https://issues.apache.org/jira/browse/SOLR-2449) [SOLR-2450](https://issues.apache.org/jira/browse/SOLR-2450) [SOLR-2505](https://issues.apache.org/jira/browse/SOLR-2505)
    (Stanislaw Osinski, Dawid Weiss)
  • SOLR-2496: Add ability to specify overwrite and commitWithin as request parameters (e.g. specified in the URL) when using the JSON update format, and added a simplified format for specifying multiple documents. Example: [{"id":"doc1"},{"id":"doc2"}]

  • SOLR-2390: Performance of usePhraseHighlighter is terrible on very large Documents, regardless of hl.maxDocCharsToAnalyze.
    (Mark Miller)
  • SOLR-2403: facet.sort=index reported incorrect results for distributed search in a number of scenarios when facet.mincount>0. This patch also adds some performance/algorithmic improvements when (facet.sort=count && facet.mincount=1 && facet.limit=-1) and when
    (facet.sort=index && facet.mincount>0, yonik)
  • SOLR-2409: edismax parser - treat the text of a fielded query as a literal if the fieldname does not exist. For example Mission: Impossible should not search on the "Mission" field unless it's a valid field in the schema.
    (Ryan McKinley, yonik)
  • SOLR-2445: Change the default qt to blank in form.jsp, because there is no "standard" request handler unless you have it in your solrconfig.xml explicitly.

  • SOLR-2464: Fix potential slowness in QueryValueSource (the query() function) when the query is very sparse and may not match any documents in a segment.
    (yonik)
  • SOLR-2466: SolrJ's CommonsHttpSolrServer would retry requests on failure, regardless of the configured maxRetries, due to HttpClient having its own retry mechanism by default. The retryCount of HttpClient is now set to 0, and SolrJ does the retry.
    (yonik)
  • SOLR-2467: Fix <analyzer class="..." /> initialization so any errors are logged properly.
    (hossman)
  • SOLR-2469: When using java replication with replicateAfter=startup, the first commit point on server startup is never removed.
    (yonik)
  • SOLR-2474: The helper TokenStreams in analysis.jsp and AnalysisRequestHandlerBase did not clear all attributes so they displayed incorrect attribute values for tokens in later filter stages.
    (uschindler, rmuir, yonik)
  • SOLR-2493: SolrQueryParser was fixed to not parse the SolrConfig DOM tree on each instantiation which is a huge slowdown.
    (Stephane Bailliez, uschindler)
  • SOLR-2495: The JSON parser could hang on corrupted input and could fail to detect numbers that were too large to fit in a long.
    (yonik)
  • SOLR-2520: Make JSON response format escape \u2029 as well as \u2028 in strings since those characters are not valid in javascript strings (although they are valid in JSON strings).
    (yonik)
  • SOLR-2536: Add ReloadCacheRequestHandler to fix ExternalFileField bug (if reopenReaders set to true and no index segments have been changed, commit cannot trigger reload external file).
    (koji)
  • SOLR-2539: VectorValueSource.floatVal incorrectly used byteVal on sub-sources.
    (Tom Liu, yonik)
  • SOLR-2554: RandomSortField didn't work when used in a function query.

    (Tommaso Teofili, koji)
  • SOLR-2451: Enhance assertJQ to allow individual tests to specify the tolerance delta used in numeric equalities. This allows for slight variance in asserting score comparisons in unit tests.
    (David Smiley, Chris Hostetter)
  • SOLR-2485: Deprecate BaseResponseWriter, GenericBinaryResponseWriter, and GenericTextResponseWriter. These classes will be removed in 4.0.
    (ryan)
  • SOLR-2528: Remove default="true" from HtmlEncoder in example solrconfig.xml, because html encoding confuses non-ascii users.

  • SOLR-1128: Added metadata output to extraction request handler "extract only" option.
    (gsingers)
  • SOLR-1131: FieldTypes can now output multiple Fields per Type and still be searched. This can be handy for hiding the details of a particular implementation such as in the spatial case.

QuerySenderListender is the only implementation in Solr that implements this, but outside implementations may wish to. See the AbstractSolrEventListener for a helper method.
    (gsingers)
  • SOLR-1240: "Range Faceting" has been added. This is a generalization of the existing "Date Faceting" logic so that it now supports any all stock numeric field types that support range queries in addition to dates. facet.date is now deprecated in favor of this generalized mechanism.

    (Steven Rowe, rmuir)
  • SOLR-1750: SolrInfoMBeanHandler added for simpler programmatic access to info currently available from registry.jsp and stats.jsp
    (ehatcher, hossman)
  • SOLR-1804: Re-enabled clustering component on trunk, updated to latest version of Carrot2. No more LGPL run-time dependencies. This release of C2 also does not have a specific Lucene dependency.

  • SOLR-2010: Added ability to verify that spell checking collations have actual results in the index.
    (James Dyer, gsingers)
  • SOLR-2015: Add a boolean attribute autoGeneratePhraseQueries to TextField. autoGeneratePhraseQueries="true" (the default) causes the query parser to generate phrase queries if multiple tokens are generated from a single non-quoted analysis string. For example WordDelimiterFilter splitting text:pdp-11 will cause the parser to generate text:"pdp 11" rather than (text:PDP OR text:11). Note that autoGeneratePhraseQueries="true" tends to not work well for non whitespace delimited languages.
    (yonik)
  • SOLR-2021: Add SolrEncoder plugin to Highlighter.
    (koji)
  • SOLR-2030: Make FastVectorHighlighter use of SolrEncoder.

    (Peter Karich, rmuir)
  • SOLR-2099: Add ability to throttle rsync based replication using rsync option --bwlimit.
    (Brandon Evans, koji)

    (Tommaso Teofili, rmuir)
  • SOLR-2133: Function query parser can now parse multiple comma separated value sources. It also now fails if there is extra unexpected text after parsing the functions, instead of silently ignoring it. This allows expressions like q=dist(2,vector(1,2),$pt)&pt=3,4
    (yonik)
  • SOLR-2157: Suggester should return alpha-sorted results when onlyMorePopular=false
    (ab)

    (Tom Burton-West, rmuir)
  • SOLR-2237: Added StempelPolishStemFilterFactory to contrib/analysis-extras
    (rmuir)
  • SOLR-2263: Add ability for RawResponseWriter to stream binary files as well as text files.
    (Eric Pugh, yonik)

    (Brad Giaccio, Dawid Weiss, Stanislaw Osinski, rmuir, koji)
  • SOLR-2325: Allow tagging and exclusion of main query for faceting.
    (yonik)
  • SOLR-243: Add configurable IndexReaderFactory so that alternate IndexReader implementations can be specified via solrconfig.xml. Note that using a custom IndexReader may be incompatible with ReplicationHandler (see comments in SOLR-1366). This should be treated as an experimental feature. [SOLR-1366](https://issues.apache.org/jira/browse/SOLR-1366)
    (Andrzej Bialecki, hossman, Mark Miller, John Wang)
  • SOLR-284: Added support for extracting content from binary documents like MS Word and PDF using Apache Tika. See also contrib/extraction/CHANGES.txt
    (Eric Pugh, Chris Harris, yonik, gsingers)
  • SOLR-397: Date Faceting now supports a "facet.date.include" param for specifying when the upper & lower end points of computed date ranges should be included in the range. Legal values are: "all", "lower", "upper", "edge", and "outer". For backwards compatibility the default value is the set: [lower,upper,edge], so that all ranges between start and end are inclusive of their endpoints, but the "before" and "after" ranges are not.
  • SOLR-465: Add configurable DirectoryProvider so that alternate Directory implementations can be specified via solrconfig.xml. The default DirectoryProvider will use NIOFSDirectory for better concurrency on non Windows platforms.
    (Mark Miller, TJ Laurenzo, yonik)
  • SOLR-538: Add maxChars attribute for copyField function so that the length limit for destination can be specified.
    (Georgios Stamatis, Lars Kotthoff, Chris Harris, koji)
  • SOLR-540: Add support for globbing in field names to highlight. For example, hl.fl=*_text will highlight all fieldnames ending with _text.
    (Lars Kotthoff, yonik)
  • SOLR-560: Use SLF4J logging API rather then JDK logging. The packaged .war file is shipped with a JDK logging implementation, so logging configuration for the .war should be identical to solr 1.3. However, if you are using the .jar file, you can select which logging implementation to use by dropping a different binding. See: http://www.slf4j.org/
    (ryan)
  • SOLR-561: Added Replication implemented in Java as a request handler. Supports index replication as well as configuration replication and exposes detailed statistics and progress information on the Admin page. Works on all platforms.
    (Noble Paul, yonik, Akshay Ukey, shalin)

  • SOLR-739: Add support for OmitTf
    (Mark Miller, yonik)
  • SOLR-744: ShingleFilterFactory supports the "outputUnigramsIfNoShingles" parameter, to output unigrams if the number of input tokens is fewer than minShingleSize, and no shingles can be generated.

    (Lars Kotthoff, yonik)
  • SOLR-785: Distributed Search support for SpellCheckComponent
    (Matthew Woytowitz, shalin)
  • SOLR-793: Add 'commitWithin' argument to the update add command. This behaves similar to the global autoCommit maxTime argument except that it is set for each request.
    (ryan)
  • SOLR-795: SpellCheckComponent supports building indices on optimize if configured in solrconfig.xml
    (Jason Rennie, shalin)
  • SOLR-799: Add support for hash based exact/near duplicate document handling.
    (Mark Miller, yonik)
  • SOLR-801: DIH: Add support for configurable pre-import and post-import delete query per root-entity.
    (Noble Paul, shalin)
  • SOLR-811: Allow a "deltaImportQuery" attribute in SqlEntityProcessor which is used for delta imports instead of DataImportHandler manipulating the SQL itself.
    (Noble Paul, shalin)
  • SOLR-812: Configurable JDBC settings in JdbcDataSource including optimized defaults for read only mode.
    (David Smiley, Glen Newton, shalin)

    (koji)
  • SOLR-829: Allow slaves to request compressed files from master during replication
    (Simon Collins, Noble Paul, Akshay Ukey, shalin)
  • SOLR-833: DIH: A DataSource to read data from a field as a reader. This can be used, for example, to read XMLs residing as CLOBs or BLOBs in databases.
    (Noble Paul, shalin)

  • SOLR-1656: XIncludes and other HREFs in XML files loaded by ResourceLoader are fixed to be resolved using the URI standard (RFC 2396). The system identifier is no longer a plain filename with path, it gets initialized using a custom URI scheme "solrres:". This scheme is resolved using a EntityResolver that utilizes ResourceLoader (org.apache.solr.common.util.SystemIdResolver). This makes all relative pathes in Solr's config files behave like expected. This change introduces some backwards breaks in the API: Some config classes (Config, SolrConfig, IndexSchema) were changed to take org.xml.sax.InputSource instead of InputStream. There may also be some backwards breaks in existing config files, it is recommended to check your config files / XSLTs and replace all XIncludes/HREFs that were hacked to use absolute paths to use relative ones.

  • SOLR-1769: Solr 1.4 Replication - Repeater throwing NullPointerException (noble) ================== Release 1.4.0 ================== Release Date: See http://lucene.apache.org/solr for the official release date. Upgrading from Solr 1.3 ----------------------- There is a new default faceting algorithm for multiVaued fields that should be faster for most cases. One can revert to the previous algorithm (which has also been improved somewhat) by adding facet.method=enum to the request. Searching and sorting is now done on a per-segment basis, meaning that the FieldCache entries used for sorting and for function queries are created and used per-segment and can be reused for segments that don't change between index updates. While generally beneficial, this can lead to increased memory usage over 1.3 in certain scenarios: 1) A single valued field that was used for both sorting and faceting in 1.3 would have used the same top level FieldCache entry. In 1.4, sorting will use entries at the segment level while faceting will still use entries at the top reader level, leading to increased memory usage. 2) Certain function queries such as ord() and rord() require a top level FieldCache instance and can thus lead to increased memory usage. Consider replacing ord() and rord() with alternatives, such as function queries based on ms() for date boosting. If you use custom Tokenizer or TokenFilter components in a chain specified in schema.xml, they must support reusability. If your Tokenizer or TokenFilter maintains state, it should implement reset(). If your TokenFilteFactory does not return a subclass of TokenFilter, then it should implement reset() and call reset() on its input TokenStream. TokenizerFactory implementations must now return a Tokenizer rather than a TokenStream. New users of Solr 1.4 will have omitTermFreqAndPositions enabled for non-text indexed fields by default, which avoids indexing term frequency, positions, and payloads, making the index smaller and faster. If you are upgrading from an earlier Solr release and want to enable omitTermFreqAndPositions by default, change the schema version from 1.1 to 1.2 in schema.xml. Remove any existing index and restart Solr to ensure that omitTermFreqAndPositions completely takes affect. The default QParserPlugin used by the QueryComponent for parsing the "q" param has been changed, to remove support for the deprecated use of ";" as a separator between the query string and the sort options when no "sort" param was used. Users who wish to continue using the semi-colon based method of specifying the sort options should explicitly set the defType param to "lucenePlusSort" on all requests.
    (The simplest way to do this is by specifying it as a default param for your request handlers in solrconfig.xml, see the example solrconfig.xml for sample syntax.)

  • SOLR-1369: Add HSQLDB Jar to example-DIH, unzip database and update instructions. ================== Release 1.3.0 ================== Upgrading from Solr 1.2 ----------------------- IMPORTANT UPGRADE NOTE: In a master/slave configuration, all searchers/slaves should be upgraded before the master! If the master were to be updated first, the older searchers would not be able to read the new index format. The Porter snowball based stemmers in Lucene were updated (LUCENE-1142), and are not guaranteed to be backward compatible at the index level (the stem of certain words may have changed). Re-indexing is recommended. Older Apache Solr installations can be upgraded by replacing the relevant war file with the new version. No changes to configuration files should be needed. This version of Solr contains a new version of Lucene implementing an updated index format. This version of Solr/Lucene can still read and update indexes in the older formats, and will convert them to the new format on the first index change. Be sure to backup your index before upgrading in case you need to downgrade. Solr now recognizes HTTP Request headers related to HTTP Caching (see RFC 2616 sec13) and will by default respond with "304 Not Modified" when appropriate. This should only affect users who access Solr via an HTTP Cache, or via a Web-browser that has an internal cache, but if you wish to suppress this behavior an '<httpCaching never304="true"/>' option can be added to your solrconfig.xml. See the wiki (or the example solrconfig.xml) for more details... http://wiki.apache.org/solr/SolrConfigXml#HTTPCaching In Solr 1.2, DateField did not enforce the canonical representation of the ISO 8601 format when parsing incoming data, and did not generation the canonical format when generating dates from "Date Math" strings (particularly as it pertains to milliseconds ending in trailing zeros). As a result equivalent dates could not always be compared properly. This problem is corrected in Solr 1.3, but DateField users that might have been affected by indexing inconsistent formats of equivalent dates (ie: 1995-12-31T23:59:59Z vs 1995-12-31T23:59:59.000Z) may want to consider reindexing to correct these inconsistencies. Users who depend on some of the "broken" behavior of DateField in Solr 1.2 (specificly: accepting any input that ends in a 'Z') should consider using the LegacyDateField class as a possible alternative. Users that desire 100% backwards compatibility should consider using the Solr 1.2 version of DateField. Due to some changes in the lifecycle of TokenFilterFactories, users of Solr 1.2 who have written Java code which constructs new instances of StopFilterFactory, SynonymFilterFactory, or EnglishProterFilterFactory will need to modify their code by adding a line like the following prior to using the factory object... factory.inform(SolrCore.getSolrCore().getSolrConfig().getResourceLoader()); These lifecycle changes do not affect people who use Solr "out of the box" or who have developed their own TokenFilterFactory plugins. More info can be found in SOLR-594. The python client that used to ship with Solr is no longer included in the distribution [LUCENE-1142](https://issues.apache.org/jira/browse/LUCENE-1142) [SOLR-594](https://issues.apache.org/jira/browse/SOLR-594)

  • SOLR-1595: StreamingUpdateSolrServer used the platform default character set when streaming updates, rather than using UTF-8 as the HTTP headers indicated, leading to an encoding mismatch.
    (hossman, yonik)
  • SOLR-1596: A rollback operation followed by the shutdown of Solr or the close of a core resulted in a warning: "SEVERE: SolrIndexWriter was not closed prior to finalize()" although there were no other consequences.

This allows a RequestHandler or SearchComponent to know when a newSearcher or firstSearcher event happened. QuerySenderListender is the only implementation in Solr that implements this, but outside implementations may wish to. See the AbstractSolrEventListener for a helper method.
    (gsingers)
  • SOLR-1256: Show the output of CharFilters in analysis.jsp.
    (koji)
  • SOLR-1266: Added stemEnglishPossessive option (default=true) to WordDelimiterFilter that allows disabling of english possessive stemming

Release 1.3.0 [2008-09-16]

• Added   (73)
  • SOLR-102: Added RegexFragmenter, which splits text for highlighting based on a given pattern.
    (klaas)
  • SOLR-1129: Support binding dynamic fields to beans in SolrJ
    (Avlesh Singh, noble)
  • SOLR-127: HTTP Caching awareness. Solr now recognizes HTTP Request headers related to HTTP Caching (see RFC 2616 sec13) and will respond with "304 Not Modified" when appropriate. New options have been added to solrconfig.xml to influence this behavior.
    (Thomas Peuss, hossman)
  • SOLR-133: Added StaxUpdateRequestHandler that uses StAX for XML parsing. This implementation has much better error checking and lets you configure a custom UpdateRequestProcessor that can selectively process update requests depending on the request attributes. This class will likely replace XmlUpdateRequestHandler.
    (Thorsten Scherler, ryan)
  • SOLR-133: The UpdateRequestHandler now accepts multiple delete options within a single request. For example, sending: <delete><id>1</id><id>2</id></delete> will delete both 1 and 2.
    (ryan)
  • SOLR-14: Add preserveOriginal flag to WordDelimiterFilter
    (Geoffrey Young, Trey Hyde, Ankur Madnani, yonik)
  • SOLR-142: Added RawResponseWriter and ShowFileRequestHandler. This returns config files directly. If AdminHandlers are configured, this will be added automatically. The jsp files /admin/get-file.jsp and /admin/raw-schema.jsp have been deprecated. The deprecated <admin><gettableFiles> will be automatically registered with a ShowFileRequestHandler instance for backwards compatibility.
    (ryan)
  • SOLR-176: Add detailed timing data to query response output. The SearchHandler interface now returns how long each section takes.
    (klaas)
  • SOLR-193: Adding SolrDocument and SolrInputDocument to represent documents outside of the lucene Document infrastructure. This class will be used by clients and for processing documents.
    (ryan)
  • SOLR-196: A PHP serialized "phps" response writer that returns a serialized array that can be used with the PHP function unserialize, and a PHP response writer "php" that may be used by eval.
    (Nick Jenkin, Paul Borgermans, Pieter Berkel, yonik)
  • SOLR-20: Added a java client interface with two implementations. One implementation uses commons httpclient to connect to solr via HTTP. The other connects to solr directly. Check client/java/solrj. This addition also includes tests that start jetty and test a connection using the full HTTP request cycle.
    (Darren Erik Vengroff, Will Johnson, ryan)
  • SOLR-225: Enable pluggable highlighting classes. Allow configurable highlighting formatters and Fragmenters.
    (ryan)
  • SOLR-240: New <lockType> configuration setting in <mainIndex> and <indexDefaults> blocks supports all Lucene builtin LockFactories. 'single' is recommended setting, but 'simple' is default for total backwards compatibility.
    (Will Johnson, hossman)
  • SOLR-244: Added ModifiableSolrParams - a SolrParams implementation that help you change values after initialization.
    (ryan)
  • SOLR-248: Added CapitalizationFilterFactory that creates tokens with normalized capitalization. This filter is useful for facet display, but will not work with a prefix query. (ryan) SOLR-468: Change to the semantics to keep the original token, not the token in the Map. Also switched to use Lucene's new reusable token capabilities. [SOLR-468](https://issues.apache.org/jira/browse/SOLR-468)
    (gsingers)
  • SOLR-253: Adding KeepWordFilter and KeepWordFilterFactory. A TokenFilter that keeps tokens with text in the registered keeplist. This behaves like the inverse of StopFilter.
    (ryan)
  • SOLR-256: Support exposing Solr statistics through JMX
    (Sharad Agrawal, shalin)
  • SOLR-257: WordDelimiterFilter has a new parameter splitOnCaseChange, which can be set to 0 to disable splitting "PowerShot" => "Power" "Shot".
    (klaas)
  • SOLR-258: Date Faceting added to SimpleFacets. Facet counts computed for ranges of size facet.date.gap (a DateMath expression) between facet.date.start and facet.date.end.
    (hossman)
  • SOLR-260: Converting to a standard PluginLoader framework. This reworks RequestHandlers, FieldTypes, and QueryResponseWriters to share the same base code for loading and initializing plugins. This adds a new configuration option to define the default RequestHandler and QueryResponseWriter in XML using default="true".
    (ryan)
  • SOLR-264: Added RandomSortField, a utility field with a random sort order. The seed is based on a hash of the field name, so a dynamic field of this type is useful for generating different random sequences. This field type should only be used for sorting or as a value source in a FunctionQuery
    (ryan, hossman, yonik)
  • SOLR-266: Adding show=schema to LukeRequestHandler to show the parsed schema fields and field types.
    (ryan)
  • SOLR-269: Added UpdateRequestProcessor plugin framework. This provides a reasonable place to process documents after they are parsed and before they are committed to the index. This is a good place for custom document manipulation or document based authorization.
    (yonik, ryan)
  • SOLR-273: /376/452/516: Added hl.maxAnalyzedChars highlighting parameter, defaulting to 50k, hl.alternateField, which allows the specification of a backup field to use as summary if no keywords are matched, and hl.mergeContiguous, which combines fragments if they are adjacent in the source document.
    (klaas, Grant Ingersoll, Koji Sekiguchi, klaas)
  • SOLR-281: Added a 'Search Component' interface and converted StandardRequestHandler and DisMaxRequestHandler to use this framework.
    (Sharad Agarwal, Henri Biestro, yonik, ryan)
  • SOLR-291: Control maximum number of documents to cache for any entry in the queryResultCache via queryResultMaxDocsCached solrconfig.xml entry.
    (Koji Sekiguchi, yonik)
  • SOLR-303: Distributed Search over HTTP. Specification of shards argument causes Solr to query those shards and merge the results into a single response. Querying, field faceting (sorted only), query faceting, highlighting, and debug information are supported in distributed mode.
    (Sharad Agarwal, Patrick O'Leary, Sabyasachi Dalal, Stu Hood, Jayson Minard, Lars Kotthoff, ryan, yonik)
  • SOLR-305: analysis.jsp can be given a fieldtype instead of a field name.
    (hossman)
  • SOLR-307: Added NGramFilterFactory and EdgeNGramFilterFactory.
    (Thomas Peuss, Otis Gospodnetic)
  • SOLR-308: A new UUIDField class which accepts UUID string values, as well as the special value of "NEW" which triggers generation of a new random UUID.
    (Thomas Peuss, hossman)
  • SOLR-319: Changed SynonymFilterFactory to "tokenize" synonyms file. To use a tokenizer, specify "tokenizerFactory" attribute in <filter>. For example: <tokenizer class="solr.CJKTokenizerFactory"/> <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" expand="true" ignoreCase="true" tokenizerFactory="solr.CJKTokenizerFactory"/>
    (koji)
  • SOLR-334: Pluggable query parsers. Allows specification of query type and arguments as a prefix on a query string.
    (yonik)
  • SOLR-349: New FunctionQuery functions: sum, product, div, pow, log, sqrt, abs, scale, map. Constants may now be used as a value source.
    (yonik)
  • SOLR-350: Support multiple SolrCores running in the same solr instance and allows runtime runtime management for any running SolrCore. If a solr.xml file exists in solr.home, this file is used to instanciate multiple cores and enables runtime core manipulation. For more informaion see: http://wiki.apache.org/solr/CoreAdmin
    (Henri Biestro, ryan)
  • SOLR-351: External Value Source. An external file may be used to specify the values of a field, currently usable as a ValueSource in a FunctionQuery.
    (yonik)
  • SOLR-356: Pluggable functions (value sources) that allow registration of new functions via solrconfig.xml
    (Doug Daniels, yonik)
  • SOLR-359: Add field type className to Luke response, and enabled access to the detailed field information from the solrj client API.
    (Grant Ingersoll, ehatcher)
  • SOLR-395: Many new features for the spell checker implementation, including an extended response mode with much richer output, multi-word spell checking, and a bevy of new and renamed options (see the wiki).
    (Mike Krimerman, Scott Taber, klaas)
  • SOLR-408: Added PingRequestHandler and deprecated SolrCore.getPingQueryRequest(). Ping requests should be configured using standard RequestHandler syntax in solrconfig.xml rather then using the <pingQuery></pingQuery> syntax.
    (Karsten Sperling, ryan)
  • SOLR-414: Plugin initialization now supports SolrCore and ResourceLoader "Aware" plugins. Plugins that implement SolrCoreAware or ResourceLoaderAware are informed about the SolrCore/ResourceLoader.
    (Henri Biestro, ryan)
  • SOLR-418: Adding a query elevation component. This is an optional component to elevate some documents to the top positions (or exclude them) for a given query.
    (ryan)
  • SOLR-423: Added Request Handler close hook notification so that RequestHandlers can be notified when a core is closing.
    (gsingers, ryan)
  • SOLR-446: TextResponseWriter can write SolrDocuments and SolrDocumentLists the same way it writes Document and DocList.
    (yonik, ryan)
  • SOLR-447: Added an single request handler that will automatically register all standard admin request handlers. This replaces the need to register (and maintain) the set of admin request handlers. Assuming solrconfig.xml includes: <requestHandler name="/admin/" class="org.apache.solr.handler.admin.AdminHandlers" /> This will register: Luke/SystemInfo/PluginInfo/ThreadDump/PropertiesRequestHandler.
    (ryan)
  • SOLR-469: Added DataImportHandler as a contrib project which makes indexing data from Databases, XML files and HTTP data sources into Solr quick and easy. Includes API and implementations for supporting multiple data sources, processors and transformers for importing data. Supports full data imports as well as incremental (delta) indexing.

  • SOLR-920: Cache and reuse IndexSchema . A new attribute added in solr.xml called 'shareSchema'
    (noble)
• Changed   (10)
  • SOLR-276: improve JSON writer speed.
    (yonik)
  • SOLR-310: bound and reduce memory usage by providing <maxBufferedDeletes> parameter, which flushes deleted without forcing the user to use <commit/> for this purpose.
    (klaas)
  • SOLR-330: Converted TokenStreams to use Lucene's new char array based capabilities.
    (gsingers)
  • SOLR-342: Added support into the SolrIndexWriter for using several new features of the new LuceneIndexWriter, including: setRAMBufferSizeMB(), setMergePolicy(), setMergeScheduler. Also, added support to specify Lucene's autoCommit functionality (not to be confused with Solr's similarily named autoCommit functionality) via the <luceneAutoCommit> config. item. See the test and example solrconfig.xml <indexDefaults> section for usage. Performance during indexing should be significantly increased by moving up to 2.3 due to Lucene's new indexing capabilities. Furthermore, the setRAMBufferSizeMB makes it more logical to decide on tuning factors related to indexing. For best performance, leave the mergePolicy and mergeScheduler as the defaults and set ramBufferSizeMB instead of maxBufferedDocs. The best value for this depends on the types of documents in use. 32 should be a good starting point, but reports have shown up to 48 MB provides good results. Note, it is acceptable to set both ramBufferSizeMB and maxBufferedDocs, and Lucene will flush based on whichever limit is reached first.
    (gsingers)
  • SOLR-348: short-circuit faceting if less than mincount docs match.
    (yonik)

    (ryan, yonik)
• Other   (38)
  • SOLR-135: Moved common classes to org.apache.solr.common and altered the build scripts to make two jars: apache-solr-1.3.jar and apache-solr-1.3-common.jar. This common.jar can be used in client code; It does not have lucene or junit dependencies.

Release 1.2.0 [2007-06-06]

• Added   (36)
  • SOLR-104: Support for "Update Plugins" -- RequestHandlers that want access to streams of data for doing updates. ContentStreams can come from the raw POST body, multi-part form data, or remote URLs. Included in this change is a new SolrDispatchFilter that allows RequestHandlers registered with names that begin with a "/" to be accessed using a URL structure based on that name.
    (Ryan McKinley, hossman)
  • SOLR-106: New faceting parameters that allow specification of a minimum count for returned facets (facet.mincount), paging through facets (facet.offset, facet.limit), and explicit sorting (facet.sort). facet.zeros is now deprecated.
    (yonik)
  • SOLR-107: JAVA API: Change NamedList to use Java5 generics and implement Iterable<Map.Entry>
    (Ryan McKinley, yonik)
  • SOLR-116: IndexInfoRequestHandler added.
    (Erik Hatcher)
  • SOLR-117: Limit a field faceting to constraints with a prefix specified by facet.prefix or f.<field>.facet.prefix.
    (yonik)
  • SOLR-126: DirectUpdateHandler2 supports autocommitting after a specified time (in ms), using <autoCommit><maxTime>10000</maxTime></autoCommit>.
    (Ryan McKinley, klaas)
  • SOLR-149: Changes to make Solr more easily embeddable, in addition to logging which request handler handled each request.
    (Ryan McKinley, yonik)
  • SOLR-152: DisMaxRequestHandler now supports configurable alternate behavior when q is not specified. A "q.alt" param can be specified using SolrQueryParser syntax as a mechanism for specifying what query the dismax handler should execute if the main user query (q) is blank.
    (Ryan McKinley, hossman)
  • SOLR-158: new "qs" (Query Slop) param for DisMaxRequestHandler allows for specifying the amount of default slop to use when parsing explicit phrase queries from the user.
    (Adam Hiatt, hossman)
  • SOLR-162: Added a "Luke" request handler and other admin helpers. This exposes the system status through the standard requestHandler framework.
    (ryan)
  • SOLR-170: StandardRequestHandler now supports a "sort" parameter. Using the ';' syntax is still supported, but it is recommended to transition to the new syntax.
    (ryan)
  • SOLR-181: The index schema now supports "required" fields. Attempts to add a document without a required field will fail, returning a descriptive error message. By default, the uniqueKey field is a required field. This can be disabled by setting required=false in schema.xml.
    (Greg Ludington, ryan)
  • SOLR-182: allow lazy loading of request handlers on first request.
    (Ryan McKinley, yonik)
  • SOLR-184: add echoHandler=true to responseHeader, support echoParams=all
    (Ryan McKinley, ehatcher)
  • SOLR-197: New parameters for input: stream.contentType for specifying or overriding the content type of input, and stream.file for reading local files.
    (Ryan McKinley, yonik)
  • SOLR-199: new n-gram tokenizers available via NGramTokenizerFactory and EdgeNGramTokenizerFactory.
    (Adam Hiatt, yonik)
  • SOLR-204: The request dispatcher (added in SOLR-104) can handle calls to /select. This offers uniform error handling for /update and /select. To enable this behavior, you must add: <requestDispatcher handleSelect="true" > to your solrconfig.xml See the example solrconfig.xml for details. [SOLR-104](https://issues.apache.org/jira/browse/SOLR-104)
    (ryan)
  • SOLR-208: new example_rss.xsl and example_atom.xsl to provide more examples for people about the Solr XML response format and how they can transform it to suit different needs.
    (Brian Whitman, hossman)
  • SOLR-211: Added a regex PatternTokenizerFactory. This extracts tokens from the input string using a regex Pattern.
    (Ryan McKinley)
  • SOLR-212: Added a DirectSolrConnection class. This lets you access solr using the standard request/response formats, but does not require an HTTP connection. It is designed for embedded applications.
    (ryan)
  • SOLR-217: Fields configured in the schema to be neither indexed or stored will now be quietly ignored by Solr when Documents are added. The example schema has a comment explaining how this can be used to ignore any "unknown" fields.
    (Will Johnson, hossman)
  • SOLR-224: Adding a PhoneticFilterFactory that uses apache commons codec language encoders to build phonetically similar tokens. This currently supports: DoubleMetaphone, Metaphone, Soundex, and RefinedSoundex
    (ryan)
  • SOLR-226: Added support for dynamic field as the destination of a copyField using glob (*) replacement.
    (ryan)
  • SOLR-227: If schema.xml defines multiple fieldTypes, fields, or dynamicFields with the same name, a severe error will be logged rather then quietly continuing. Depending on the <abortOnConfigurationError> settings, this may halt the server. Likewise, if solrconfig.xml defines multiple RequestHandlers with the same name it will also add an error.
    (ryan)
  • SOLR-234: TrimFilter can update the Token's startOffset and endOffset if updateOffsets="true". By default the Token offsets are unchanged.
    (ryan)
  • SOLR-249: Deprecated SolrException( int, ... ) constructors in favor of constructors that takes an ErrorCode enum. This will ensure that all SolrExceptions use a valid HTTP status code.
    (ryan)
  • SOLR-386: Abstracted SolrHighlighter and moved existing implementation to DefaultSolrHighlighter. Adjusted SolrCore and solrconfig.xml so that highlighter is configurable via a class attribute. Allows users to use their own highlighter implementation.
    (Tricia Williams, klaas)
  • SOLR-66: CSV data format for document additions and updates.
    (yonik)
  • SOLR-79: Add system property ${<sys.prop>[:<default>]} substitution for configuration files loaded, including schema.xml and solrconfig.xml.
    (Erik Hatcher with inspiration from Andrew Saar)
  • SOLR-80: Negative queries are now allowed everywhere. Negative queries are generated and cached as their positive counterpart, speeding generation and generally resulting in smaller sets to cache. Set intersections in SolrIndexSearcher are more efficient, starting with the smallest positive set, subtracting all negative sets, then intersecting with all other positive sets.
    (yonik)
  • SOLR-81: More SpellCheckerRequestHandler enhancements, inlcluding support for relative or absolute directory path configurations, as well as RAM based directory.
    (hossman)
  • SOLR-81: SpellCheckerRequestHandler that uses the SpellChecker from the Lucene contrib.
    (Otis Gospodnetic, Adam Hiatt)
  • SOLR-82: Default field values can be specified in the schema.xml.
    (Ryan McKinley, hossman)
  • SOLR-86: Added standalone Java-based command-line updater.
    (Erik Hatcher, Bertrand Delecretaz)
  • SOLR-89: Two new TokenFilters with corresponding Factories... * TrimFilter - Trims leading and trailing whitespace from Tokens * PatternReplaceFilter - applies a Pattern to each token in the stream, replacing match occurances with a specified replacement.
    (hossman)
  • SOLR-91: allow configuration of a limit of the number of searchers that can be warming in the background. This can be used to avoid out-of-memory errors, or contention caused by more and more searchers warming in the background. An error is thrown if the limit specified by maxWarmingSearchers in solrconfig.xml is exceeded.
    (yonik)
• Changed   (4)
  • SOLR-114: HashDocSet specific implementations of union() and andNot() for a 20x performance improvement for those set operations, and a new hash algorithm speeds up exists() by 10% and intersectionSize() by 8%.
    (yonik)
  • SOLR-115: Solr now uses BooleanQuery.clauses() instead of BooleanQuery.getClauses() in any situation where there is no risk of modifying the original query.
    (hossman)
  • SOLR-221: Added a facet.enum.cache.minDf parameter which avoids using the filterCache for terms that match few documents, trading decreased memory usage for increased query time.
    (yonik)
  • SOLR-221: Speed up sorted faceting on multivalued fields by ~60% when the base set consists of a relatively large portion of the index.
    (yonik)
• Fixed   (15)
  • SOLR-104: Changed the SOLR-104 RequestDispatcher so that /select?qt=xxx can not access handlers that start with "/". This makes path based authentication possible for path based request handlers.
    (ryan)
  • SOLR-145: Fix for bug introduced in SOLR-104 where some Exceptions were being ignored by all "out of the box" RequestHandlers. [SOLR-104](https://issues.apache.org/jira/browse/SOLR-104)
    (hossman)
  • SOLR-166: JNDI solr.home code refactoring. SOLR-104 moved some JNDI related code to the init method of a Servlet Filter - according to the Servlet Spec, all Filter's should be initialized prior to initializing any Servlets, but this is not the case in at least one Servlet Container (Resin). This "bug fix" refactors this JNDI code so that it should be executed the first time any attempt is made to use the solr.home dir. [SOLR-104](https://issues.apache.org/jira/browse/SOLR-104)
    (Ryan McKinley, hossman)
  • SOLR-167: The SynonymFilter sometimes generated incorrect offsets when multi token synonyms were mached in the source text.
    (yonik)
  • SOLR-168: Fix display positioning of multiple tokens at the same position in analysis.jsp
    (yonik)
  • SOLR-173: Bug fix to SolrDispatchFilter to reduce "too many open files" problem was that SolrDispatchFilter was not closing requests when finished. Also modified ResponseWriters to only fetch a Searcher reference if necessary for writing out DocLists.
    (Ryan McKinley, hossman)
  • SOLR-188: bin scripts do not support non-default webapp names. Added "-U" option to specify a full path to the update url, overriding the "-h" (hostname), "-p" (port) and "-w" (webapp name) parameters.
    (Jeff Rodenburg, billa)
  • SOLR-198: RunExecutableListener always waited for the process to finish, even when wait="false" was set.
    (Koji Sekiguchi, yonik)
  • SOLR-207: Changed distribution scripts to remove recursive find and avoid use of "find -maxdepth" on platforms where it is not supported.
    (yonik)
  • SOLR-214: Some servlet containers (including Tomcat and Resin) do not obey the specified charset. Rather than letting the container handle it solr now uses the charset from the header contentType to decode posted content. Using the contentType: "text/xml; charset=utf-8" will force utf-8 encoding. If you do not specify a contentType, it will use the platform default.
    (Koji Sekiguchi, ryan)
  • SOLR-222: Changing writeLockTimeout in solrconfig.xml did not change the effective timeout.
    (Koji Sekiguchi, yonik)
  • SOLR-241: Undefined system properties used in configuration files now cause a clear message to be logged rather than an obscure exception thrown.
    (Koji Sekiguchi, ehatcher)
  • SOLR-87: Parsing of synonym files did not correctly handle escaped whitespace such as \r\n\t\b\f.
    (yonik)
  • SOLR-9: Tighten up sort specification error checking, throw exceptions for missing sort specifications or a sort on a non-indexed field. [SOLR-99](https://issues.apache.org/jira/browse/SOLR-99)
    (Ryan McKinley, yonik)
  • SOLR-92: DOMUtils.getText (used when parsing config files) did not work properly with many DOM implementations when dealing with "Attributes".
    (Ryan McKinley, hossman)
• Other   (14)
  • SOLR-104: The example solrconfig.xml maps /update to XmlUpdateRequestHandler using the new request dispatcher (SOLR-104). This requires posted content to have a valid contentType: curl -H 'Content-type:text/xml; charset=utf-8' The response format matches that of /select and returns standard error codes. To enable solr1.1 style /update, do not map "/update" to any handler in solrconfig.xml
    (ryan)
  • SOLR-125: Change default of json.nl to flat, change so that json.nl only affects items where order matters (facet constraint listings). Fix JSON output bug for null values. Internal JAVA API: change most uses of NamedList to SimpleOrderedMap.
    (yonik)
  • SOLR-128: Upgraded Jetty to the latest stable release 6.1.3
    (ryan)
  • SOLR-179: By default, solr will abort after any severe initialization errors. This behavior can be disabled by setting: <abortOnConfigurationError>false</abortOnConfigurationError> in solrconfig.xml
    (ryan)
  • SOLR-183: Exceptions with error code 400 are raised when numeric argument parsing fails. RequiredSolrParams class added to facilitate checking for parameters that must be present.
    (Ryan McKinley, J.J. Larrea, yonik)
  • SOLR-230: More options for post.jar to support stdin, xml on the commandline, and defering commits. Tutorial modified to take advantage of these options so there is no need for curl.
    (hossman)
  • SOLR-231: If a charset is not specified in the contentType, ContentStream.getReader() will use UTF-8 encoding.
    (ryan)
  • Highlighting using DisMax will only pick up terms from the main user query, not boost or filter queries
    (klaas)
  • A new method "getSolrQueryParser" has been added to the IndexSchema class for retrieving a new SolrQueryParser instance with all options specified in the schema.xml's <solrQueryParser> block set. The documentation for the SolrQueryParser constructor and its use of IndexSchema have also been clarified.
    (Erik Hatcher, hossman)
  • DisMaxRequestHandler's bq, bf, qf, and pf parameters can now accept multiple values
    (klaas)
  • Query are re-written before highlighting is performed. This enables proper highlighting of prefix and wildcard queries
    (klaas)
  • A meaningful exception is raised when attempting to add a doc missing a unique id if it is declared in the schema and allowDups=false.
    (ryan, klaas)
  • Updated to Lucene 2.1
  • Updated to Lucene 2007-05-20_00-04-53

    (Bertrand Delacretaz, yonik)
  • SOLR-31: JSON, Python, Ruby QueryResponseWriters: use wt="json", "python" or "ruby" SOLR-31
    (yonik)
  • SOLR-35: Make web admin pages return UTF-8, change Content-type declaration to include a space between the mime-type and charset SOLR-35
    (Philip Jacob)
  • SOLR-39: JAVA API: new version of SolrIndexSearcher.getDocListAndSet() which takes flags SOLR-39
    (Greg Ludington, yonik)
  • SOLR-41: A HyphenatedWordsFilter, a text analysis filter used during indexing to rejoin words that were hyphenated and split by a newline. SOLR-41
    (Boris Vitez, yonik)
  • SOLR-44: Simple faceted search support for fields (enumerating terms) and arbitrary queries added to both StandardRequestHandler and DisMaxRequestHandler. SOLR-44
    (hossman)
  • SOLR-45: Added a CompressableField base class which allows fields of derived types to be compressed using the compress=true setting. The field type also gains the ability to specify a size threshold at which field data is compressed. SOLR-45
    (klaas)
  • SOLR-46: In addition to specifying default RequestHandler params in the solrconfig.xml, support has been added for configuring values to be appended to the multi-val request params, as well as for configuring invariant params that can not overridden in the query. SOLR-46
    (hossman)
  • SOLR-49: New XSLTResponseWriter does server side XSLT processing of XML Response. In the process, an init(NamedList) method was added to QueryResponseWriter which works the same way as SolrRequestHandler. SOLR-49
    (Bertrand Delacretaz, hossman)
  • SOLR-56: json.wrf parameter adds a wrapper-function around the JSON response, useful in AJAX with dynamic script tags for specifying a JavaScript callback function. SOLR-56
    (Bertrand Delacretaz, yonik)
  • SOLR-65: autoCommit can be specified every so many documents added SOLR-65
    (klaas)
  • SOLR-68: ${solr.home}/lib directory can now be used for specifying "plugin" jars SOLR-68
    (hossman)
  • SOLR-71: Support for "Date Math" relative "NOW" when specifying values of a DateField in a query -- or when adding a document. SOLR-71
    (hossman)
  • SOLR-77: useColdSearcher control in solrconfig.xml prevents the first searcher from being used before it's done warming. This can help prevent thrashing on startup when multiple requests hit a cold searcher. The default is "false", preventing use before warm. SOLR-77
    (yonik)
  • added support for setting Lucene's positionIncrementGap
  • Admin: new statistics for SolrIndexSearcher
  • Admin: caches now show config params on stats page
  • max() function added to FunctionQuery suite
  • postOptimize hook, mirroring the functionallity of the postCommit hook, but only called on an index optimize.
  • Ability to HTTP POST query requests to /select in addition to HTTP-GET
  • The default search field may now be overridden by requests to the standard request handler using the df query parameter.
    (Erik Hatcher)
  • Added DisMaxRequestHandler and SolrPluginUtils.
    (Chris Hostetter)
  • Added KeywordTokenizerFactory
    (hossman)
  • new DocSet.andNot(), DocSet.andNotSize
    (yonik)
  • Made query parser default operator configurable via schema.xml: <solrQueryParser defaultOperator="AND|OR"/> The default operator remains "OR".
  • Default operator for query parsing can now be specified with q.op=AND|OR from the client request, overriding the schema value.
    (ehatcher)
• Changed   (6)
  • SOLR-15: OpenBitSet completed, replaces BitSet as the implementation for BitDocSet. Iteration is faster, and BitDocSet.intersectionSize(BitDocSet) and unionSize is between 3 and 4 times faster. SOLR-15
    (yonik)
  • getDocListAndSet can now generate both a DocList and a DocSet from a single lucene query.
  • BitDocSet.intersectionSize(HashDocSet) no longer generates an intermediate set
  • much faster unionSize when one of the sets is a HashDocSet: O
    (smaller_set_size)
  • Optimized getDocSet() for term queries resulting in a 36% speedup of facet.field queries where DocSets aren't cached
    (for example, if the number of terms in the field is larger than the filter cache., yonik)
  • Optimized facet.field faceting by as much as 500 times when the field has a single token per document (not multiValued & not tokenized) by using the Lucene FieldCache entry for that field to tally term counts. The first request utilizing the FieldCache will take longer than subsequent ones.
• Fixed   (13)
  • SOLR-32: Worked around a Jetty bug that caused invalid XML responses for fields containing non ASCII chars. SOLR-32
    (Bertrand Delacretaz, yonik)
  • SOLR-34: WordDelimiterFilter can throw exceptions if configured with both generate and catenate off. SOLR-34
    (Mike Klaas, yonik)
  • SOLR-65: Multiple-doc update generates well-formed xml SOLR-65
    (klaas)
  • SOLR-70: Better parsing of pingQuery from solrconfig.xml SOLR-70
    (hossman)
  • SOLR-74: Fixed HTML escaping issues with user input to analysis.jsp and action.jsp SOLR-74
    (hossman)
  • Fixed delete-by-id for field types who's indexed form is different from the printable form
    (mainly sortable numeric types)
  • Added escaping of attribute values in the XML response
    (Erik Hatcher)
  • Added empty extractTerms() to FunctionQuery to enable use in a MultiSearcher
    (Yonik)
  • WordDelimiterFilter sometimes lost token positionIncrement information
  • Fix reverse sorting for fields were sortMissingFirst=true
    (Rob Staveley, yonik)
  • Escape '>' in XML output ([because ]]> is illegal in CharData]())
  • field boosts weren't being applied and doc boosts were being applied to fields
    (klaas)
  • Fixed bug with "Distribution" page introduced when Versions were added to "Info" page
    (hossman)
• Other   (26)
  • SOLR-18: Included unique key field name/value (if available) in log message of add SOLR-18
    (billa)
  • SOLR-25: FunctionQuery.explain now uses ComplexExplanation to provide more accurate score explanations when composed in a BooleanQuery. SOLR-25
    (hossman)
  • SOLR-3: Removed src/apps containing the legacy "SolrTest" app SOLR-3
    (hossman)
  • SOLR-37: Highlighter params changed to be prefixed with "hl."; allow fragmentsize customization and per-field overrides on many options SOLR-37
    (Andrew May, klaas)
  • SOLR-43: Default param values for DisMaxRequestHandler should now be specified using a '<lst name="defaults">...</lst>' init param, for backwards compatability all init prams will be used as defaults if an init param with that name does not exist. SOLR-43
    (hossman)
  • SOLR-44: The DisMaxRequestHandler now supports multiple occurances of the "fq" param. SOLR-44
    (hossman)
  • SOLR-48: Added javascript to catch empty query in admin query forms (Tomislav Nakic-Alfirevic via billa, SOLR-48
  • SOLR-52: Lazy field loading can be enabled via a solrconfig directive. This will be faster when not all stored fields are needed from a document SOLR-52
    (klaas)
  • SOLR-58: Made admin JSPs return XML and transform them with new XSL stylesheets SOLR-58
    (Otis Gospodnetic)
  • SOLR-59: If the "echoParams=explicit" request parameter is set, request parameters are copied to the output. In an XML output, they appear in new <lst name="params"> list inside the new <lst name="responseHeader"> element, which replaces the old <responseHeader>. Adding a version=2.1 parameter to the request produces the old format, for backwards compatibility SOLR-59
    (bdelacretaz, yonik)
  • SOLR-6: Modified admin styles to improve display in Internet Explorer SOLR-6
    (Greg Ludington, billa)

    (klaas)
  • SOLR-78: Config parsing should now work useing DOM Level 2 parsers -- Solr previously relied on getTextContent which is a DOM Level 3 addition SOLR-78
    (Alexander Saar, hossman)
  • classes reorganized into different packages, package names changed to Apache
