I revise the code to
SortField sortField[] = {new SortField("id", new
CustomComparatorSource(bitSet)),SortField.FIELD_SCORE};
Sort sort = new Sort(sortField);
TopFieldCollector topFieldCollector =
TopFieldCollector.create(sort, 1000, true, true, true, true);
indexSearcher.search(query, topFieldCollector);
TopDocs topDocs = topFieldCollector.topDocs();
but I got the same result with the previous code, need I custom the
class TopFieldCollector?
thank you lan
