BulkScorer |
bulkScorer(LeafReaderContext context,

Optional method, to return a
BulkScorer to
score the query and send hits to a Collector. |
Explanation |
explain(LeafReaderContext context,
int doc)
An explanation of the score computation for the named document.

getValueForNormalization()
The value for normalization of contained query clauses (e.g.
|
void |
normalize(float norm,
float topLevelBoost)
Assigns the query normalization factor and boost from parent queries to this.
|
Scorer |
scorer(LeafReaderContext context,
Bits acceptDocs)
Returns a
Scorer which scores documents in/out-of order according
to scoreDocsInOrder. |

WeightBulkScorer to
score the query and send hits to a Collector.
Only queries that have a different top-level approach
need to override this; the default implementation
pulls a normal Scorer and iterates and
collects the resulting hits.bulkScorer in class Weightcontext - the LeafReaderContext for which to return the Scorer.acceptDocs - Bits that represent the allowable docs to match (typically deleted docs

NOTE: null can be returned if no documents will be scored by this query.
