Date Mon, 05 Mar 2012 19:13:58 GMT

Thanks Robert, I've got it working now. I just set my default similarity to {{SchemaSimilarityFactory}}
and it works just as it did before.

> As part of adding additional scoring systems to lucene, we made a lower-level Similarity
> and the existing stuff became e.g. TFIDFSimilarity which extends it.
> However, I always feel bad about the complexity introduced here (though I do feel there
> are some "excuses", that its a difficult challenge).
> In order to try to mitigate this, we also exposed an easier API (SimilarityBase) on top
> it that makes some assumptions (and trades off some performance) to try to provide something

> consumable for e.g. experiments.
> Still, we can cleanup a few things with the low-level api: fix outdated documentation
> shoot for better/clearer naming etc.
