I try 2 way for get count results:
1)
Query q = ....
IndexSearcher is = ....
int count = Is.search(q).length();
2)
Query q = ....
IndexSearcher is = ....
CountCollector collector = new CountCollector();
Is.search(q, collector);
Int count = collector.getCount();
First way return results for 1.644 sec.
Second way return results fot 3.088 sec.
Why first way faster then second?
Can I accelerate it? And how? Can you offer any ways for get number of
results?
----------------------CountCollector
import org.apache.lucene.search.HitCollector;
/**

public class CountCollector extends HitCollector {
private int numberRusults = 0;
public int getCount() {
return numberRusults;
}
public CountCollector() {
}
public void collect(int doc, float score) {
if (score > 0.0f) {
numberRusults++;
}
}
}
