score
Description copied from class:Scorable
Returns the score of the current document matching the query.- Overrides:

- Throws:
IOException

getMaxScore
Description copied from class:Scorer
Return the maximum score that documents between the lasttarget
that this iterator wasshallow-advanced

advanceShallow
Description copied from class:Scorer
Advance to the block of documents that containstarget
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 >=Scorer.docID()
as well as all targets that have been passed toScorer.advanceShallow(int)
so far.- Overrides:
advanceShallow
in classScorer
- Throws:
IOException

setMinCompetitiveScore
Description copied from class:Scorable
Optional method: Tell the scorer that its iterator may safely ignore all documents whose score is less than the givenminScore
. This is a no-op by default.This method may only be called from collectors that use
ScoreMode.TOP_SCORES
, and successive calls may only set increasing values ofminScore
.- Overrides:
setMinCompetitiveScore
in classScorable
- Throws:
IOException
