Does anyone have any examples? This is what am trying to do, how do I get the score?


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

        int size = bits.length();

        String[] values = new String[size];
        String type = null;
        ArrayList results = new ArrayList(size);

        for (int i = 0,j = size; i < j; i++) {
            final Document document = searcher.doc(i);
            type = document.get("TYPE");
            //hits.doc(i).get("TYPE");
            values[i] = document.get("ID");
//            System.out.println("score = " + score);
// how do i get the score???
//            resultsMap.put(hits.doc(i).get("ID"), new Float(score));

        }
