in order to get scoring information about this block. This method is implicitly called byDocIdSetIterator.advance(int)
andDocIdSetIterator.nextDoc()
on the returned doc ID. Calling this method doesn't modify the currentDocIdSetIterator.docID()
. It returns a number that is greater than or equal to all documents contained in the current block, but less than any doc IDS of the next block.target
must be >=Scorable.docID()
as well as all targets that have been passed toScorer.advanceShallow(int)
so far.- Overrides:
