Hi, Lucene uses a variant version of vector space model for ranking the documents.
You can look at 1) http://lucene.apache.org/java/docs/api/org/apache/lucene/search/Similarity.htmlfor the fomula, 2) there is an article some one wrote about the Lucene's Ranking function vs. standard vsm. However, that link has been removed and I think it does not exist anymore. I still keep a copy of that file, so, you may download it from my website at the following url: http://jhsystems.net:9090/lucene_ranking.pdf Let me know of any other problem.
