Hi Otis,
as my colleague said, we have a first implementation of BM25 over Lucene, this
development is part of a (almost finished) thesis project that compares
different IR models, over an standard collection. At the same time we are trying
to extend this first implementation in order to support BM25F for multifield
queries, unfortunately at this time we are too busy to prepare a final version
of this code, so we will have to finish this code over the summer (hopefully we
will have more time :-))), and make it public at this time.
We will inform to this list when we will finish the preparation of a final
version.
Thanks to everybody for the interest!!!
Bye Joaquin

Hi Jose,
I was wondering if you ever got to this. I would love to see and try BM25 for Lucene!
I'm looking at http://code.google.com/soc/2008/asf/about.html and it looks like this didn't make it into GSoC, but this would still be great to have.
Thanks, Otis

we have almost implemented BM25 using lucene structure, but we need help to finish query parser and other details. If you o somebody want We can send you the code and you can help us to implement the query parser and prepare the code to sandbox.
If there are people interested I can made a web page for the project and put our implementatio to download
Somebody is interested?

would you mind a GSOC project to implement BM25 relevancy/scoring?
