setScorer
public void setScorer(Scorable scorer)
Description copied from interface:LeafCollector
Called before successive calls toLeafCollector.collect(int)
. Implementations that need the score of the current document (passed-in toLeafCollector.collect(int)
), should save the passed-in Scorer and call scorer.score() when needed.- Specified by:
setScorer
in interfaceLeafCollector
-
collect
public void collect(int doc) throws java.io.IOException
Description copied from interface:LeafCollector
Called once for every document matching a query, with the unbased document number.Note: The collection of the current segment can be terminated by throwing a
CollectionTerminatedException
. In this case, the last docs of the currentLeafReaderContext
will be skipped andIndexSearcher
will swallow the exception and continue collection with the next leaf.Note: This is called in an inner search loop. For good search performance, implementations of this method should not call
IndexSearcher.doc(int)
orIndexReader.document(int)
on every hit. Doing so can slow searches by an order of magnitude or more.- Specified by:
collect
in interfaceLeafCollector
- Throws:
java.io.IOException
