sorry guys to have not been responding & thanks a lot for answers. @Erick Erickson: what I would ideally like to have is tf-idf value for user's query. The thing is that we have two searchable fields. While boost works just fine for one, there is no easy way to have it multiplied by boost from another field (with current parser).
@Erik Hatcher: interesting idea, how have I missed it :) Is there a way to capture the value and push it through to other field's boost function?
