Doron Cohen commented on LUCENE-2986:
-------------------------------------
+1 for this change (I did not remember discussing this, but other than
remembering I am consistent :))
Patch looks very clean.
Minor technical comments - concerning just some tests:
- some of the DSP implementations are still named xyzSimilarity - I think it
would be more clear to name them xyzSimilarityProvider:
-- o.a.l.search.payloads.TestPayloadNearQuery.BoostingSimilarity
-- o.a.l.search.payloads.TestPayloadTermQuery.BoostingSimilarity
-- o.a.solr.schema.MockConfigurableSimilarity
-- o.a.l.index.TestIndexWriterConfig.MySimilarity
-- o.a.l.index.TestIndexReaderCloneNorms.SimilarityOne
-- o.a.l.index.TestNorms.SimilarityOne
-- o.a.l.index.TestOmitTf.SimpleSimilarity
-- o.a.l.search.TestSimilarity.SimpleSimilarity
- for few of the above it is not only the name - they are still doing both
roles: {code}extends DefaultSimilarity implements SimilarityProvider{code}:
-- o.a.l.search.payloads.TestPayloadNearQuery.BoostingSimilarity
-- o.a.l.search.payloads.TestPayloadTermQuery.BoostingSimilarity
-- o.a.l.index.TestOmitTf.SimpleSimilarity
-- o.a.l.search.TestSimilarity.SimpleSimilarity
Other than that I think it is good to go in.
Also, tests from trunk/lucene and trunk/solr passed.
(I am seeing problems in running all trunk tests, at least on Windows, but I'll
send a separate mail to the list on that)

>
> In LUCENE-2236 as a start, we made DefaultSimilarity which implements the
> factory interface (SimilarityProvider), and also extends Similarity.
> Its factory interface just returns itself always by default.
> Doron mentioned it would be cleaner to split the two, and I thought it would
> be good to revisit it later.
> Today as I was looking at SOLR-2338, it became pretty clear that we should do
> this, it makes things a lot cleaner. I think currently its confusing to users
> to see the two apis mixed if they are trying to subclass.
