Hi, I need to override Lucene Default Similarity Class which is used by Elasticsearch for indexing and searching. On searching net, I found some similar implementations which are doing similar things. My difficulty is that I have no idea of how to actually implement this in my code. I found some resources: > **[tlrx/elasticsearch-custom-similarity-provider](https://github.com/tlrx/elasticsearch-custom-similarity-provider)** > > elasticsearch-custom-similarity-provider - A custom SimilarityProvider example for Elasticsearch curl -XPOST '[http://host](http://host):port/tweeter/' -d '{ "settings": { "similarity": { "index": { "type": "org.elasticsearch.index.similarity.CustomSimilarityProvider" }, "search": { "type": "org.elasticsearch.index.similarity.CustomSimilarityProvider" } } }}' I'm not able to understand how can i use this line directly during indexing so that my default similarity changes to this custom similarity. _org.elasticsearch.index.similarity.CustomSimilarityProvider_ Can anyone please tell me how I can do this ? I tried running the same thing on my machine but it's not working for me. Do I need to modify this line or path ?

I have read about that module but the thing is I have to set idf to 1. Actually, I want common terms to give more weight in my search. Now, when I googled about it, it says overriding the default similarity class is the only way to achieve it. That's the reason why I'm looking for these plugins.

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.

I was focused on how to use a custom similarity and not how to actually tackle the problem. In this respect, I agree with Jörg. Also, I believe the today's release (1.0.0.RC1) has additional scripting options: > **[Elasticsearch Platform — Find real-time answers at scale](https://www.elastic.co)** > > Power insights and outcomes with the Elasticsearch Platform and AI.

Using the function\_score you could use a script. Since 0.90.10 you can access term statistics from a script ([Add support for using payloads to boost terms · Issue #3772 · elastic/elasticsearch · GitHub](https://github.com/elasticsearch/elasticsearch/issues/3772)), term frequency included. You could for instance emit your own score that takes into account only the term frequency but not the idf.
