Hi Harry, May be you can use BooleanQuery#setMinimumNumberShouldMatch method. What happens when you use set it to half of the numTerms?

After test, I found that when query is long(above 10 terms). And the speed of searching is too slow near to 1s. I think the bottleneck is that I used OR to generate my BooleanQuery. It would get plenty of candidates documents. And it would also consume too many time to score and rank. I changed to use AND to generate my BooleanQuery. But it decrease the accuracy of hits. So I want to find a solution to reduce candidate documents and do not decrease the accuracy in this situation.
