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.
