Constructor Summary

Constructors

Constructor	Description
ConcurrentSortedSetDocValuesFacetCounts(SortedSetDocValuesReaderState state, ExecutorService exec)	Returns all facet counts, same result as searching on MatchAllDocsQuery but faster.
ConcurrentSortedSetDocValuesFacetCounts(SortedSetDocValuesReaderState state, FacetsCollector hits, ExecutorService exec)	Counts all facet dimensions across the provided hits.

Method Summary

Modifier and Type	Method	Description
private void	count(List<FacetsCollector.MatchingDocs> matchingDocs)	Does all the "real work" of tallying up the counts.
private void	countAll()	Does all the "real work" of tallying up the counts.
(package private) int	getCount(int ord)	Retrieve the count for a specified ordinal.
(package private) boolean	hasCounts()	Were any counts actually computed? (They may not be if there are no hits, etc.)
