Subject Lucene 1.2 - scoring forumla needed
Date Sat, 09 Sep 2006 22:35:36 GMT

I am looking for a mathematically correct IR scoring formula for Lucene 1.2. The description
in the book (Lucene in Action, 2005 edition) is rather non-mathematical, also I am not sure
if this is the one that also counts for Lucene 1.2 and not for later versions.

Perhaps Eric or Otis can directy comment on this? Is there any paper on the Lucene scoring
algorithm that was published and describes the formula in depth?

Best Regards,
