Hi Otis, I hope this is not off-topic,
Apparently in Lucene similarity does not have to be set at index time: See http://lucene.apache.org/core/4_0_0/changes/Changes.html under Lucene 2959 "All models default to the same index-time norm encoding as DefaultSimilarity, so you can easily try these out/switch back and forth/run experiments and comparisons without re-indexing." Does Solr expose this ability to change similarities without re-indexing? i.e could you just change your schema?
