Class BulkScorer

java.lang.Object

org.apache.lucene.search.BulkScorer

Direct Known Subclasses:

ConstantScoreQuery.ConstantBulkScorer

public abstract class BulkScorer
extends Object

This class is used to score a range of documents at once, and is returned by Weight.bulkScorer(org.apache.lucene.index.LeafReaderContext, org.apache.lucene.util.Bits). Only queries that have a more optimized means of scoring across a range of documents need to override this. Otherwise, a default implementation is wrapped around the Scorer returned by Weight.scorer(org.apache.lucene.index.LeafReaderContext, org.apache.lucene.util.Bits).
