I would like to write a custom collector ( similar to the one which is inside
the source of TopScoreDocCollector like InOrderTopScoreDocCollector). The
reason for extending this is because InOrderTopScoreDocCollector and
OutOfOrderTopScoreDocCollector are private to the class and I really wanted
to override the collect(int doc) method to have some custom logic
incorporated. Could someone please let me know if this approach would work
fine? or does have any issues?
Here is what I am thinking:
public class MyCollector extends TopScoreDocCollector {
public MyCollector (int numHits) {
super(numHits);
}
@Override
public void collect(int doc) throws IOException {
float score = scorer.score();
// Add a check here
if(score < 0.0f) {
return;
}
// remaining code
}
@Override
public boolean acceptsDocsOutOfOrder() {
return true;
}
}
