Hi, how do you hide it, i.e., how is the normization done?

The FAQ states that scores range from 0 to 1. Scores from Hits are normalized so that the top score is never greater than 1.0. Scores passed to a HitCollector are raw. It is very possible in Lucene to get scores that are greater than 1.0. This bothers some folks, so Hits hides it, however it's difficult to hide it from a HitCollector.
