Weight
Scorer
which scores documents in/out-of order according
to scoreDocsInOrder
.
NOTE: even if scoreDocsInOrder
is false, it is
recommended to check whether the returned Scorer
indeed scores
documents out of order (i.e., call Weight.scoresDocsOutOfOrder()
), as
some Scorer
implementations will always return documents
in-order.
NOTE: null can be returned if no documents will be scored by this
query.
scorer
in class SpanWeight
context
- the AtomicReaderContext
for which to return the Scorer
.scoreDocsInOrder
- specifies whether in-order scoring of documents is required. Note
that if set to false (i.e., out-of-order scoring is required),
this method can return whatever scoring mode it supports, as every
in-order scorer is also an out-of-order one. However, an
out-of-order scorer may not support DocIdSetIterator.nextDoc()
and/or DocIdSetIterator.advance(int)
, therefore it is recommended to
request an in-order scorer if use of these methods is required.topScorer
- if true, Scorer.score(Collector)
will be called; if false,
DocIdSetIterator.nextDoc()
and/or DocIdSetIterator.advance(int)
will
be called.acceptDocs
- Bits that represent the allowable docs to match (typically deleted docs
but possibly filtering other documents)Scorer
