Hi Erik,
Thanks for the suggestion.
I tried this:
public class RelevanceSimilarity extends DefaultSimilarity
{
public float tf(float freq) {
System.out.println("discounting frequency");
return (float)1;
}
}
and in my query class, I used :
Similarity.setDefault(similarity);
Hits hits = is.search(query);
for(i = 0; i < hits.length(); i ++)
result = result + hits.score(i);
However, this is still not giving me the expected result. Do I need to do
something else?
Regards,
Niraj
