setScorer
public void setScorer(Scorable scorer) throws IOException
Description copied from interface:LeafCollectorCalled 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:

collect
public void collect(int doc) throws IOExceptionDescription copied from interface:LeafCollectorCalled 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 currentLeafReaderContextwill be skipped andIndexSearcherwill 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:
