Subject Moving SweetSpotSimilarity out of contrib
Date Tue, 02 Sep 2008 10:07:53 GMT

Following Doron's quality work enhancements in TREC 2007 (,
I was wondering if it's possible to move the SweetSpotSimilarity to Lucene's
main code stream (out of "contrib" that is).
It shows significant improvement over the default similarity.

I'm not suggesting to replace the DefaultSimilarity (as the default) with
SweetSpot, but just expose SweetSpot as part of Lucene's core. It will help
me use it, since I cannot use the contrib packages easily in my environment
(legal issues), but can use Lucene's core more freely.

Any objections?
