Otis Gospodnetic commented on LUCENE-2091:
------------------------------------------
Has anyone compared this particular BM25 impl. to the current Lucene's
quasi-VSM approach in terms of:
* any of the relevance eval methods
* indexing performance
* search performance
* ...
Also, this issue is marked as contrib/*. Should this not go straight to core,
so more people actually use this and provide feedback? Who knows, there is a
chance (ha!) BM25 might turn out better than the current approach, and become
the default.

> 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.
