Examples of FacetsCollector

org.apache.lucene.facet.FacetsCollector
Collects hits for subsequent faceting. Once you've run a search and collect hits into this, instantiate one of the {@link Facets} subclasses to do the facetcounting. Use the {@code search} utility methods toperform an "ordinary" search but also collect into a {@link Collector}.
org.apache.lucene.facet.search.FacetsCollector
A {@link Collector} which executes faceted search and computes the weight ofrequested facets. To get the facet results you should call {@link #getFacetResults()}. {@link #create(FacetSearchParams,IndexReader,TaxonomyReader)} returns themost optimized {@link FacetsCollector} for the given parameters. @lucene.experimental
