Description

http://nlp.uned.es/~jperezi/Lucene-BM25/ describes an implementation of Okapi-BM25 scoring in the Lucene framework,
as an alternative to the standard Lucene scoring (which is a version of mixed boolean/TFIDF).
I have refactored this a bit, added unit tests and improved the runtime somewhat.
I would like to contribute the code to Lucene under contrib.
