Subject Re: BM25 model for solr 4?
Date Thu, 15 Nov 2012 04:51:27 GMT
See http://wiki.apache.org/solr/SchemaXml#Similarity

class="solr.BM25SimilarityFactory"

The factories for these have javadocs that document the parameters:
http://lucene.apache.org/solr/4_0_0/solr-core/org/apache/solr/search/similarities/package-summary.html

I don't know about comparisons between the choices available.  I'd love to
see one.
