(String dim, String... path) Returns all child labels with non-zero counts under the specified path.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.getSpecificValue
(String dim, String... path) Return the count or value for a specific path.getTopChildren
(int topN, String dim, String... path) Returns the topN child labels under the specified path.Methods inherited from class org.apache.lucene.facet.FacetCountsWithFilterQuery
