Called once for every document matching a query, with the document number and its raw score.

If, for example, an application wished to collect all of the hits for a query in a BitSet, then it might:

            Searcher searcher = new IndexSearcher(indexReader);
            final BitSet bits = new BitSet(indexReader.maxDoc());
            searcher.search(query, new HitCollector() {
            public void collect(int doc, float score) {
            bits.set(doc);
            }
            });

Note: This is called in an inner search loop. For good search performance, implementations of this method should not call {@link Searcher#Doc(int)} or {@link Lucene.Net.Index.IndexReader#Document(int)} on every document number encountered. Doing so can slow searches by an order of magnitude or more.

Note: The

score
passed to this method is a raw score. In other words, the score will not necessarily be a float whose value is between 0 and 1.
