Subject [jira] [Commented] (LUCENE-4801) Documentation is incorrect for org.apache.lucene.misc.SweetSpotSimilarity
Date Tue, 26 Feb 2013 22:10:15 GMT


Andrew Schoen commented on LUCENE-4801:

FWIW, I was able to get SweetSpotSimilarity like results by using BM25SimilarityFactory and
tweaking the `b` parameter.

> The documentation for SweetSpotSimilarity says that you can configure a global min/max
and also a min/max per field, however at looking at the source and just trying to accomplish
this it looks as though it's not possible.  Is that correct?
> I looked into using SchemaSimilarityFactory as a global Similarity and then using SweetSpotSimilarity
on a fieldType, but was not able to configure the min and max values.  Is there a way to accomplish
that without writing my own SweetSpotSimilarityFactory?
> Thanks.
