scorer
public Scorer scorer(LeafReaderContext context) throws java.io.IOException
Description copied from class:Weight
Returns aScorer
which can iterate in order over all matching documents and assign them a score.NOTE: null can be returned if no documents will be scored by this query.
NOTE: The returned
Scorer
does not haveLeafReader.getLiveDocs()
applied, they need to be checked on top.- Specified by:
