@Deprecated
public final class BitsFilteredDocIdSet
extends FilteredDocIdSet

This implementation supplies a filtered DocIdSet, that excludes all docids which are not in a Bits instance. This is especially useful in Filter to apply the acceptDocs passed to getDocIdSet() before returning the final DocIdSet.
