[CLucene-dev] Ordering results

[Mike A. <mi...@au...>]

I am doing a query and want to sort all the matched data by one of the
fields (date).

Whats the best way of doing this ?


The search will potentially match a lot of rows - so for performance I've
subclassed HitCollector and am adding all the returned documentIDs to a
list of integers if that makes any difference :


 reader = IndexReader::open(...);
 q = QueryParser::parse(...);
 s = new IndexSearcher(reader);
 s->_search(q, NULL, &hc);





class myHitCollector : public HitCollector {

private :
       list<int32_t> hitList;

public:
        int hitListCount;

        myHitCollector() : HitCollector() {
                clear();
                hitListCount=0;
        }

        void clear() {
                hitList.clear();
        }

        void push(int32_t doc) {
                hitList.push_back(doc);
                hitListCount++;
        }

        int  pop() {
                int32_t doc=hitList.front();
                hitList.pop_front();
                hitListCount--;
                return doc;
        }

        void collect(const int32_t doc, const float_t score) {
                push(doc);
        }
};



again - is this the best way ?


Any help much appreciated!
