Lucene uses a variation of TF-TDF for the similarity score where the document length is one of the factors. In the future you will be able to modify scoring to your needs: http://www.mail-archive.com/lucene-dev@jakarta.apache.org/msg01727.html
There might be more in the FAQ or in the mail archive. This is something that has been discussed quite often. For example, you could learn about the scoring mechanism in: http://lucene.sourceforge.net/cgi-bin/faq/faqmanager.cgi?file=chapter.search&toc=faq#q31 --- Chris Sibert <[EMAIL PROTECTED]> wrote: > I am disatisfied with the document scores that I'm getting.
