List of bits() Examples

Examples of bits()

org.apache.lucene.search.BooleanFilter.bits()
Returns the a BitSet representing the Boolean composition of the filters that have been added.
org.apache.lucene.search.DocIdSet.bits()
Optionally provides a {@link Bits} interface for random accessto matching documents. @return {@code null}, if this {@code DocIdSet} does not support random access.In contrast to {@link #iterator()}, a return value of {@code null}does not imply that no documents match the filter! The default implementation does not provide random access, so you only need to implement this method if your DocIdSet can guarantee random access to every docid in O(1) time without external disk access (as {@link Bits} interface cannot throw{@link IOException}). This is generally true for bit sets like {@link org.apache.lucene.util.FixedBitSet}, which return itself if they are used as {@code DocIdSet}.
org.apache.lucene.search.Filter.bits()
@return A BitSet with true for documents which should be permitted insearch results, and false for those that should not. @deprecated Use {@link #getDocIdSet(IndexReader)} instead.
org.apache.lucene.util.BitDocIdSet.bits()
org.elasticsearch.common.lucene.docset.AndDocIdSet.bits()
