new boolean[index.getDocumentIndex().getNumberOfDocuments()]);

This worries me. Why, for every query I am scoring, must I create an array that has one entry for each of the documents in the collection. It seems just to record which docids have been used. Why not a HashSet or even better a TIntHashSet?
