Uses of Facets in org.apache.lucene.facet

Subclasses of Facets in org.apache.lucene.facet

Modifier and Type	Class	Description
class	FacetCountsWithFilterQuery	Base class for facet counts.
class	LongValueFacetCounts	Facets implementation that computes counts for all unique long values, more efficiently counting small values (0-1023) using an int array, and switching to a HashMap for values above 1023.
class	MultiFacets	Maps specified dims to provided Facets impls; else, uses the default Facets impl.
class	StringValueFacetCounts	Compute facet counts from a previously indexed SortedSetDocValues or SortedDocValues field.

Fields in org.apache.lucene.facet declared as Facets

Modifier and Type	Field	Description
final Facets	DrillSideways.DrillSidewaysResult.facets	Combined drill down and sideways results.

Methods in org.apache.lucene.facet that return Facets

Modifier and Type	Method	Description
protected Facets	DrillSideways.buildFacetsResult(FacetsCollector drillDowns, FacetsCollector[] drillSideways, String[] drillSidewaysDims)	Subclass can override to customize per-dim Facets impl.

Constructors in org.apache.lucene.facet with parameters of type Facets

Modifier	Constructor	Description
	DrillSidewaysResult(Facets facets, TopDocs hits, FacetsCollector drillDownFacetsCollector, FacetsCollector[] drillSidewaysFacetsCollector, String[] drillSidewaysDims)	Sole constructor.
	MultiFacets(Map<String,Facets> dimToFacets, Facets defaultFacets)	Create this, with the specified default Facets for fields not included in dimToFacets.

Constructor parameters in org.apache.lucene.facet with type arguments of type Facets

Modifier	Constructor	Description
	MultiFacets(Map<String,Facets> dimToFacets)	Create this, with no default Facets.
	MultiFacets(Map<String,Facets> dimToFacets, Facets defaultFacets)	Create this, with the specified default Facets for fields not included in dimToFacets.

Uses of Facets in org.apache.lucene.facet.facetset

Modifier and Type	Class	Description
class	MatchingFacetSetsCounts	Returns the counts for each given FacetSet

Uses of Facets in org.apache.lucene.facet.range

Subclasses of Facets in org.apache.lucene.facet.range

Uses of Facets in org.apache.lucene.facet.rangeonrange

Subclasses of Facets in org.apache.lucene.facet.rangeonrange

Modifier and Type	Class	Description
class	DoubleRangeOnRangeFacetCounts	Represents counts for double range on range faceting.
class	LongRangeOnRangeFacetCounts	Represents counts for long range on range faceting.

Uses of Facets in org.apache.lucene.facet.sortedset

Subclasses of Facets in org.apache.lucene.facet.sortedset

Modifier and Type	Class	Description
class	ConcurrentSortedSetDocValuesFacetCounts	Like SortedSetDocValuesFacetCounts, but aggregates counts concurrently across segments.
class	SortedSetDocValuesFacetCounts	Compute facets counts from previously indexed SortedSetDocValuesFacetField, without require a separate taxonomy index.

Uses of Facets in org.apache.lucene.facet.taxonomy

Subclasses of Facets in org.apache.lucene.facet.taxonomy

Modifier and Type	Class	Description
class	FastTaxonomyFacetCounts	Computes facets counts, assuming the default encoding into DocValues was used.
class	FloatTaxonomyFacets	Deprecated. Visibility of this class will be reduced to pkg-private in a future version.
class	IntTaxonomyFacets	Deprecated. Visibility of this class will be reduced to pkg-private in a future version.
class	TaxonomyFacetCounts	Deprecated. Custom binary encodings for taxonomy ordinals are no longer supported starting with Lucene 9.
class	TaxonomyFacetFloatAssociations	Aggregates float values associated with facet fields.
class	TaxonomyFacetIntAssociations	Aggregates int values previously indexed with IntAssociationFacetField, assuming the default encoding.
class	TaxonomyFacets	Deprecated. Visibility of this class will be reduced to pkg-private in a future version.
class	TaxonomyFacetSumFloatAssociations	Deprecated. This class is being deprecated in favor of TaxonomyFacetFloatAssociations, which provides more flexible aggregation functionality beyond just "sum"
class	TaxonomyFacetSumIntAssociations	Deprecated. This class is being deprecated in favor of TaxonomyFacetIntAssociations, which provides more flexible aggregation functionality beyond just "sum"
class	TaxonomyFacetSumValueSource	Deprecated. This class is being deprecated in favor of TaxonomyFacetFloatAssociations, which provides more flexible aggregation functionality beyond just "sum"
