Scorer
DocIdSetIterator
over matching documents.
The returned iterator will either be positioned on -1
if no
documents have been scored yet, DocIdSetIterator.NO_MORE_DOCS
if all documents have been scored already, or the last document id that
has been scored otherwise.
The returned iterator is a view: calling this method several times will
return iterators that have the same state.public float getMaxScore(int upTo) throws java.io.IOException
