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

Constructor and Description
LongValueFacetCounts(String field, FacetsCollector hits, boolean multiValued) Create LongValueFacetCounts, using either single-valued NumericDocValues or multi-valued SortedNumericDocValues from the specified field.
LongValueFacetCounts(String field, LongValuesSource valueSource, FacetsCollector hits) Create LongValueFacetCounts, using the provided LongValuesSource.
LongValueFacetCounts(String field, LongValuesSource valueSource, FacetsCollector hits, boolean multiValued) Create LongValueFacetCounts, using the provided LongValuesSource.
StringValueFacetCounts(StringDocValuesReaderState state, FacetsCollector facetsCollector) Counts facets across the provided hits.

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

Constructors in org.apache.lucene.facet.range with parameters of type FacetsCollector

Constructor and Description
DoubleRangeFacetCounts(String field, DoubleValuesSource valueSource, FacetsCollector hits, DoubleRange... ranges) Create RangeFacetCounts using the provided DoubleValuesSource
DoubleRangeFacetCounts(String field, DoubleValuesSource valueSource, FacetsCollector hits, Query fastMatchQuery, DoubleRange... ranges) Create RangeFacetCounts, using the provided DoubleValuesSource, and using the provided Query as a fastmatch: only documents matching the query are checked for the matching ranges.
DoubleRangeFacetCounts(String field, FacetsCollector hits, DoubleRange... ranges) Create RangeFacetCounts, using DoubleValues from the specified field.
LongRangeFacetCounts(String field, FacetsCollector hits, LongRange... ranges) Create LongRangeFacetCounts, using LongValuesSource from the specified field.
LongRangeFacetCounts(String field, LongValuesSource valueSource, FacetsCollector hits, LongRange... ranges) Create LongRangeFacetCounts, using the provided LongValuesSource.
LongRangeFacetCounts(String field, LongValuesSource valueSource, FacetsCollector hits, Query fastMatchQuery, LongRange... ranges) Create LongRangeFacetCounts, using the provided LongValuesSource, and using the provided Filter as a fastmatch: only documents passing the filter are checked for the matching ranges, which is helpful when the provided LongValuesSource is costly per-document, such as a geo distance.
