scorer
public Scorer scorer(LeafReaderContext context) throws IOException
Description copied from class:WeightReturns aScorerwhich 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
Scorerdoes not haveLeafReader.getLiveDocs()applied, they need to be checked on top.- Specified by:
scorerin classWeight- Parameters:
context- theLeafReaderContextfor which to return theScorer.- Returns:
- a
Scorerwhich scores documents in/out-of order. - Throws:
IOException- if there is a low-level I/O error
-
bulkScorer
public BulkScorer bulkScorer(LeafReaderContext context) throws IOException
Description copied from class:WeightOptional method, to return aBulkScorerto score the query and send hits to aCollector. Only queries that have a different top-level approach need to override this; the default implementation pulls a normalScorerand iterates and collects the resulting hits which are not marked as deleted.- Overrides:
bulkScorerin classWeight- Parameters:
context- theLeafReaderContextfor which to return theScorer.- Returns:
- a
BulkScorerwhich scores documents and passes them to a collector. - Throws:
IOException- if there is a low-level I/O error
-
isCacheable
public boolean isCacheable(LeafReaderContext ctx)
- Returns:
trueif the object can be cached against a given leaf
-
explain
public Explanation explain(LeafReaderContext context, int doc) throws IOException
Description copied from class:WeightAn explanation of the score computation for the named document.- Specified by:
explainin classWeight- Parameters:
context- the readers context to create theExplanationfor.doc- the document's id relative to the given context's reader- Returns:
- an Explanation for the score
- Throws:
IOException- if anIOExceptionoccurs
