1) For Lucene's scoring, there's this:
http://lucene.apache.org/java/2_4_0/scoring.html#Scoring
And Lucene in action also describes the scoring formula.
2) It's up to you to build a Lucene document from your content, so you
decide which parts of your content (body, link, meta) become which
fields in Lucene. At that point Lucene's scoring formula kicks in.

Subject: Lucene
Good morning,
our company works in the field of industrial biotechnologies. We
were interested in having a software capable to classify web-sites
(and so organizations) working in our field. So, one of our IT
consultants organized a system based on Heritrix (http://crawler.archive.org/
) and Lucene.
As you know, Lucene calculates some scores of frequency. We would
like to know/obtain:
1) the formula used by Lucene to calculate the scores;
2) for each page, the basic information used by Lucene to calculate
the scores (atomic data: term's frequency in meta, link, body;
dimension of the page; ...).
How can you help us to have this kind of information?
Thanks.
Marco Palumbo
