Constructor Detail

AnalyticsQuery

public AnalyticsQuery()

Use this constructor for single node analytics.

AnalyticsQuery

public AnalyticsQuery(MergeStrategy mergeStrategy)

Use this constructor for distributed analytics.

Parameters:

mergeStrategy - defines the distributed merge strategy for this AnalyticsQuery

Method Detail

getCache

public boolean getCache()

Description copied from interface: ExtendedQuery

Should this query be cached in the query cache or filter cache.

Specified by:

getCache in interface ExtendedQuery

Overrides:

getCache in class ExtendedQueryBase

getCost

public int getCost()

Description copied from interface: ExtendedQuery

Returns the cost of this query, used to order checking of filters that are not cached. If getCache()==false && getCost()>=100 && this instanceof PostFilter, then the PostFilter interface will be used for filtering. Otherwise, for smaller costs, this cost will be used for TwoPhaseIterator.matchCost().

Specified by:

getCost in interface ExtendedQuery

Overrides:

getCost in class ExtendedQueryBase

equals

public boolean equals(Object o)

Specified by:

equals in class org.apache.lucene.search.Query

hashCode

public int hashCode()

Specified by:

hashCode in class org.apache.lucene.search.Query

getFilterCollector

public DelegatingCollector getFilterCollector(org.apache.lucene.search.IndexSearcher searcher)

Description copied from interface: PostFilter

Returns a DelegatingCollector to be run after the main query and all of its filters, but before any sorting or grouping collectors

Specified by:

getFilterCollector in interface PostFilter

getAnalyticsCollector

public abstract DelegatingCollector getAnalyticsCollector(ResponseBuilder rb,
                                                          org.apache.lucene.search.IndexSearcher searcher)

visit

public void visit(org.apache.lucene.search.QueryVisitor visitor)

Specified by:

visit in class org.apache.lucene.search.Query
