Subject Superset Similarity?
Date Fri, 16 Nov 2012 04:31:15 GMT

Somebody asked about BM25 on solr-user and comparison to other relevancy
scoring methods.  Similarity has to be set at index time and should not be
changed... but is there any one Similarity that happens to be a superset of
them all, so that one can use that Similarity during indexing, and then
switch to other Similarities to query time?  I doubt it, but....maybe, just
maybe... :)
