## Uses of Class
org.apache.lucene.search.DocIdSet

Packages that use DocIdSet
org.apache.lucene.search | Code to search indices.
org.apache.lucene.util | Some utility classes.

Uses of DocIdSet in org.apache.lucene.search

Subclasses of DocIdSet in org.apache.lucene.search
`class` | `BitsFilteredDocIdSet` This implementation supplies a filtered DocIdSet, that excludes all docids which are not in a Bits instance.
`class` | `FieldCacheDocIdSet` Base class for DocIdSet to be used with FieldCache.
`class` | `FilteredDocIdSet` Abstract decorator class for a DocIdSet implementation that provides on-demand filtering/validation mechanism on a given DocIdSet.

Fields in org.apache.lucene.search declared as DocIdSet
`static DocIdSet` | `DocIdSet.EMPTY_DOCIDSET` An empty `DocIdSet` instance for easy use, e.g.

Methods in org.apache.lucene.search that return DocIdSet
`protected DocIdSet` | `CachingWrapperFilter.docIdSetToCache(DocIdSet docIdSet, AtomicReader reader)` Provide the DocIdSet to be cached, using the DocIdSet provided by the wrapped Filter.
`DocIdSet` | `QueryWrapperFilter.getDocIdSet(AtomicReaderContext context, Bits acceptDocs)`
`DocIdSet` | `MultiTermQueryWrapperFilter.getDocIdSet(AtomicReaderContext context, Bits acceptDocs)` Returns a DocIdSet with documents that should be permitted in search results.
`abstract DocIdSet` | `Filter.getDocIdSet(AtomicReaderContext context, Bits acceptDocs)` Creates a `DocIdSet` enumerating the documents that should be permitted in search results.
`DocIdSet` | `FieldValueFilter.getDocIdSet(AtomicReaderContext context, Bits acceptDocs)`
`DocIdSet` | `FieldCacheTermsFilter.getDocIdSet(AtomicReaderContext context, Bits acceptDocs)`
`abstract DocIdSet` | `FieldCacheRangeFilter.getDocIdSet(AtomicReaderContext context, Bits acceptDocs)` This method is implemented for each data type
`abstract DocIdSet` | `DocTermOrdsRangeFilter.getDocIdSet(AtomicReaderContext context, Bits acceptDocs)` This method is implemented for each data type
`DocIdSet` | `CachingWrapperFilter.getDocIdSet(AtomicReaderContext context, Bits acceptDocs)`
`static DocIdSet` | `BitsFilteredDocIdSet.wrap(DocIdSet set, Bits acceptDocs)` Convenience wrapper method: If `acceptDocs == null` it returns the original set without wrapping.

Methods in org.apache.lucene.search with parameters of type DocIdSet
`protected DocIdSet` | `CachingWrapperFilter.docIdSetToCache(DocIdSet docIdSet, AtomicReader reader)` Provide the DocIdSet to be cached, using the DocIdSet provided by the wrapped Filter.
`abstract Scorer` | `FilteredQuery.FilterStrategy.filteredScorer(AtomicReaderContext context, boolean scoreDocsInOrder, boolean topScorer, Weight weight, DocIdSet docIdSet)` Returns a filtered `Scorer` based on this strategy.
`Scorer` | `FilteredQuery.RandomAccessFilterStrategy.filteredScorer(AtomicReaderContext context, boolean scoreDocsInOrder, boolean topScorer, Weight weight, DocIdSet docIdSet)`
`static DocIdSet` | `BitsFilteredDocIdSet.wrap(DocIdSet set, Bits acceptDocs)` Convenience wrapper method: If `acceptDocs == null` it returns the original set without wrapping.

Constructors in org.apache.lucene.search with parameters of type DocIdSet
`BitsFilteredDocIdSet(DocIdSet innerSet, Bits acceptDocs)` Constructor.
`FilteredDocIdSet(DocIdSet innerSet)` Constructor.

Uses of DocIdSet in org.apache.lucene.util

Subclasses of DocIdSet in org.apache.lucene.util
`class` | `DocIdBitSet` Simple DocIdSet and DocIdSetIterator backed by a BitSet
`class` | `FixedBitSet` BitSet of fixed length (numBits), backed by accessible (`FixedBitSet.getBits()`) long[], accessed with an int index, implementing Bits and DocIdSet.
`class` | `OpenBitSet` An "open" BitSet implementation that allows direct access to the array of words storing the bits.
`class` | `OpenBitSetDISI` OpenBitSet with added methods to bulk-update the bits from a `DocIdSetIterator`.
