Discarding lengthNorm didn't work for you. Very interesting. I am not sure but
I think inverse document frequency causing problem to you. Probably one of
query word (very common word) has high document frequency, and the docs having

I am trying to boost results that have all the query in it to increase its
ranking. But both the query unfortunately does not seems to effect it

Try this:
BooleanQuery b1 = new BooleanQuery();
b1.add(new TermQuery(new Term("url", "news")),
BooleanClause.Occur.MUST);
b1.add(new TermQuery(new Term("url", "politics")),
BooleanClause.Occur.MUST);
b1.setBoost(1.5f);
BooleanQuery b2 = new BooleanQuery();
b2.add(n
Thanks a lotit is truly cause by the length normalization there. I follow
your suggestion and change it to 1.0f. Now it works properly.
Thanks again

Hmm. Interesting. It seems that length normalization causing this. Very short

If I understand you correctly: User will enter multiple keywords. Lets say a b

I didn't understand what exactly you are asking but the query string is already
well-formatted. You can pass this string directly to the parse method of
QueryParser. The following four examples yields the same Qu
