The score from the main query is passed to the customScore() methods of CustomScoreProvider so you can tweak that as you will. Or, easier, use document boosting to set a low boost for common titles. How are you going to determine if a title is common or not?
Lucene by default will tend to favour rarer terms - maybe you can achieve the same result more easily by using/tweaking an alternative Similarity implementation. -- Ian.
