Now I create new search for get number of results. For example:
IndexSearcher is = ...
Query q = ...
numberOfResults = Is.search(q).length();
Can I accelerate this example ? And how ?
Perhaps something like:
class CountingHitCollector
implements HitCollector
{
public int count;
public void collect(int doc, float score)
{
if (score > 0.0f)
++count;
}
}
...
CountingHitCollector c = new CountingHitCollector();
searcher.search(query, c);
int hits = c.count;
