org.apache.lucene.facet.index.FacetFields

org.apache.lucene.facet.sortedset.SortedSetDocValuesFacetFields

public class SortedSetDocValuesFacetFields
extends FacetFields

Add instances of this to your Document if you intend to use SortedSetDocValuesAccumulator to count facets at search time. Note that this only supports flat facets (dimension + label). Add multiple instances of this to your document, one per dimension + label, and it's fine if a given dimension is multi-valued.
