question: return a fixedbitset with a bit set for every document in this docset . the default implementation iterates on all docs and sets the relevant bits . you should override if you can provide a more efficient implementation . concode_field_sep PlaceHolder placeHolder concode_field_sep void add concode_elem_sep int intersectionSize concode_elem_sep boolean intersects concode_elem_sep int unionSize concode_elem_sep FixedBitSet toBitSet concode_elem_sep DocSet union concode_elem_sep void addUnique concode_elem_sep Filter getTopFilter concode_elem_sep int andNotSize concode_elem_sep boolean equals concode_elem_sep DocSet intersection concode_elem_sep void addAllTo concode_elem_sep void close concode_elem_sep DocSet andNot
