Examples of org.apache.lucene.facet.search.FacetArrays

org.apache.lucene.facet.search.FacetArrays
Provider of arrays used for facets aggregation. Returns either an {@code int[]} or {@code float[]} of the specified array length. When thearrays are no longer needed, you should call {@link #free()}, so that e.g. they will be reclaimed.
NOTE: if you need to reuse the allocated arrays between search requests, use {@link ReusingFacetArrays}.
NOTE: this class is not thread safe. You typically allocate it per search. @lucene.experimental
