Class DoubleRangeFacetCounts

Facets implementation that computes counts for dynamic double ranges from a provided ValueSource, using DoubleVal(Int32) or DoubleVal(Int32, Double[]). Use this for dimensions that change in real-time (e.g. a relative time based dimension like "Past day", "Past 2 days", etc.) or that change for each request (e.g. distance from the user's location, "< 1 km", "< 2 km", etc.).

If you had indexed your field using SingleDocValuesField then pass SingleFieldSource as the ValueSource; if you used DoubleDocValuesField then pass DoubleFieldSource (this is the default used when you pass just a the field name). @lucene.experimental

DoubleRangeFacetCounts(String, ValueSource, FacetsCollector, Filter, DoubleRange[])

Create RangeFacetCounts, using the provided ValueSource, and using the provided Filter as a fastmatch: only documents passing the filter are checked for the matching ranges. The filter must be random access (implement Bits).

Declaration
public DoubleRangeFacetCounts(string field, ValueSource valueSource, FacetsCollector hits, Filter fastMatchFilter, params DoubleRange[] ranges)
Parameters
Type Name Description
System.String field
ValueSource valueSource
FacetsCollector hits
Filter fastMatchFilter
DoubleRange[] ranges
