freq
float freq() throws java.io.IOException- Throws:
java.io.IOException
-
score
public float score() throws java.io.IOExceptionDescription copied from class:ScorableReturns the score of the current document matching the query.- Overrides:

java.io.IOException
-
getMaxScore
public float getMaxScore(int upTo) throws java.io.IOExceptionDescription copied from class:ScorerReturn the maximum score that documents between the lasttargetthat this iterator wasshallow-advancedto included andupToincluded.- Specified by:

java.io.IOException

advanceShallow
public int advanceShallow(int target) throws java.io.IOExceptionDescription copied from class:ScorerAdvance to the block of documents that containstargetin 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.targetmust be >=Scorable.docID()as well as all targets that have been passed toScorer.advanceShallow(int)so far.- Overrides:
advanceShallowin classScorer- Throws:
java.io.IOException

setMinCompetitiveScore
public void setMinCompetitiveScore(float minScore) throws java.io.IOExceptionDescription copied from class:ScorableOptional 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 useScoreMode.TOP_SCORES, and successive calls may only set increasing values ofminScore.- Overrides:
setMinCompetitiveScorein classScorable- Throws:
java.io.IOException
