scorer
public SpanScorer 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.- Overrides:

for which to return theScorer
.- Returns:
- a
Scorer
which scores documents in/out-of order. - Throws:
java.io.IOException
- if there is a low-level I/O error
-
isCacheable
public boolean isCacheable(LeafReaderContext ctx)
- Returns:
true
