Class Summary

Class	Description
DebugComponent	Adds debugging information to a request.
ExpandComponent	The ExpandComponent is designed to work with the CollapsingPostFilter.
FacetComponent	Computes facets -- aggregations with counts of terms or ranges over the whole search results.
FacetComponent.DistribFieldFacet	This API is experimental and subject to change
FacetComponent.FacetBase	This API is experimental and subject to change
FacetComponent.FacetContext	Encapsulates facet ranges and facet queries such that their parameters are parsed and cached for efficient re-use.
FacetComponent.FacetInfo	This class is used exclusively for merging results from each shard in a distributed facet request.
FacetComponent.FieldFacet	This API is experimental and subject to change
FacetComponent.QueryFacet	This API is experimental and subject to change
FacetComponent.ShardFacetCount	This API is experimental and subject to change
FieldFacetStats	FieldFacetStats is a utility to accumulate statistics on a set of values in one field, for facet values present in another field.
HighlightComponent	TODO!
HttpShardHandler
HttpShardHandlerFactory
IterativeMergeStrategy
IterativeMergeStrategy.CallBack
MoreLikeThisComponent	TODO!
PivotFacet	Models a single instance of a "pivot" specified by a FacetParams.FACET_PIVOT param, which may contain multiple nested fields.
PivotFacetField	Models a single field somewhere in a hierarchy of fields as part of a pivot facet.
PivotFacetFieldValueCollection	Emcapsulates a collection of PivotFacetValues associated with a PivotFacetField withs pecial tracking of a PivotFacetValue corrisponding to the null value when FacetParams.FACET_MISSING is used.
PivotFacetFieldValueCollection.PivotFacetCountComparator	Sorts PivotFacetValue instances by their count
PivotFacetFieldValueCollection.PivotFacetValueComparator	Sorts PivotFacetValue instances by their value
PivotFacetHelper
PivotFacetProcessor	Processes all Pivot facet logic for a single node -- both non-distrib, and per-shard
PivotFacetValue	Models a single (value, count) pair that will exist in the collection of values for a PivotFacetField parent.
QueryComponent	TODO!
QueryComponent.FakeScorer	Fake scorer for a single document TODO: when SOLR-5595 is fixed, this wont be needed, as we dont need to recompute sort values here from the comparator
QueryElevationComponent	A component to elevate some documents to the top of the result set.
RangeFacetProcessor	Processor for Range Facets
RangeFacetRequest	Encapsulates a single facet.range request along with all its parameters.
RangeFacetRequest.FacetRange	Represents a single facet range (or gap) for which the count is to be calculated
RealTimeGetComponent
ResponseBuilder	This class is experimental and will be changing in the future.
ResponseBuilder.GlobalCollectionStat
ResponseLogComponent	Adds to the log file the document IDs that are sent in the query response.
SearchComponent	TODO!
SearchHandler	Refer SOLR-281

SpatialHeatmapFacets	A 2D spatial faceting summary of a rectangular region.
SpatialHeatmapFacets.HeatmapFacet	Goes in FacetComponent.FacetInfo.heatmapFacets, created by SpatialHeatmapFacets.distribParse(org.apache.solr.common.params.SolrParams, ResponseBuilder).
SpellCheckComponent	A SearchComponent implementation which provides support for spell checking and suggestions using the Lucene contributed SpellChecker.
SpellCheckMergeData
StatsComponent	Stats component calculates simple statistics on numeric field values
StatsField	Models all of the information associated with a single StatsParams.STATS_FIELD instance.
StatsField.HllOptions	Helper Struct for parsing and encapsulating all of the options relaed to building a HLL
StatsValuesFactory	Factory class for creating instance of StatsValues
SuggestComponent	SuggestComponent: interacts with multiple SolrSuggester to serve up suggestions Responsible for routing commands and queries to the appropriate SolrSuggester and for initializing them as specified by SolrConfig
TermsComponent	Return TermEnum information, useful for things like auto suggest.
TermsComponent.TermsHelper
TermVectorComponent	Return term vectors for the documents in a query result set.

Enum Summary

Enum	Description
HighlightComponent.HighlightMethod
StatsField.Stat	An enumeration representing the sumer set of all possible stat values that can be computed.
