I have looked into that similarity plugin in the past and as far as I can tell, it is partially wrong. Judging by the elasticsearch code, there is no way to change the similarity depending if you are indexing or querying. The similarity is simply tied to a field and it is used at all times. Someone please correct me if I am wrong.
Besides that, writing your own similarity plugin is simple. You just need one class extending AbstractSimilarityProvider and another class with the actual similarity, which probably extends DefaultSimilarity. No need for a plugin, you just need the classes in the elasticsearch classpath at startup.
