public void collect(int doc) throws java.io.IOException
LeafCollector
Note: The collection of the current segment can be terminated by throwing
a CollectionTerminatedException
. In this case, the last docs of the
current LeafReaderContext
will be skipped and IndexSearcher
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)
or
IndexReader.document(int)
on every hit.
Doing so can slow searches by an order of magnitude or more.

. Implementations
that need the score of the current document (passed-in to
LeafCollector.collect(int)
), should save the passed-in Scorer and call
scorer.score() when needed.setScorer
