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!
