# Package org.apache.lucene.facet.sortedset

Provides faceting capabilities over facets that were indexed with `SortedSetDocValuesFacetField`.

See: Description

- Class Summary
  Class | Description
  --- | ---
  ConcurrentSortedSetDocValuesFacetCounts | Like `SortedSetDocValuesFacetCounts`, but aggregates counts concurrently across segments.
  DefaultSortedSetDocValuesReaderState | Default implementation of `SortedSetDocValuesFacetCounts`
  SortedSetDocValuesFacetCounts | Compute facets counts from previously indexed `SortedSetDocValuesFacetField`, without require a separate taxonomy index.
  SortedSetDocValuesFacetField | Add an instance of this to your Document for every facet label to be indexed via SortedSetDocValues.
  SortedSetDocValuesReaderState | Wraps a `IndexReader` and resolves ords using existing `SortedSetDocValues` APIs without a separate taxonomy index.
  SortedSetDocValuesReaderState.OrdRange | Holds start/end range of ords, which maps to one dimension (someday we may generalize it to map to hierarchies within one dimension).
