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

Method Summary
All Methods Instance Methods Concrete Methods Modifier and Type Method Description List<FacetResult>
getAllDims(int topN)
Returns topN labels for any dimension that had hits, sorted by the number of hits that dimension matched; this is used for "sparse" faceting, where many different dimensions were indexed, for example depending on the type of document.Number
getSpecificValue(String dim, String... path)
Return the count or value for a specific path.FacetResult
getTopChildren(int topN, String dim, String... path)
Returns the topN child labels under the specified path.
