[newbie] Hit quality rating
Hi!
Is there a hit quality rating in Lucene or are there only hits and non-hits?

Excellent!
I imagine support for 'long' fields won't be long off. (Stupid pun...)
Do you already know if there is any significant impact on performance
(positive or negative) when using a field rather than the score for
sorting?

Well, the original design is to have hits sorted by score.... you want
the most relevant first. Sorting defeats the purpose of a score in
many respects.
But in the latest CVS (unreleased, must build it yourself) version of
Lucene, a very slick contribution has been added to sort by an integer
field. Other datatypes are in the works.

Oops, you are right Hits.score(). But it seems I have to implement a sorting
iterator on my own :-\

There is score.
Look at Similarity class.
