Examples of org.apache.lucene.facet.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}.
