Ok, If anyone wants to disable IDF, disable TF, as to just score based on the presence of a term and boost value on the field, in elastic search v5+, then see the following plugin:

> **[farisk/elasticsearch-boolean-similarity-plugin](https://github.com/farisk/elasticsearch-boolean-similarity-plugin)**
>
> elasticsearch-boolean-similarity-plugin - Boolean similarity from Lucene made available in elasticsearch v5.x via a plugin

If you don't want to disable TF but don't know how to make a plugin, the code in the repo above should help, adding TF should be simple.

Also note some guy has implemented this into the latest elasticsearch code, see:

> <https://github.com/elastic/elasticsearch/commit/8359dd05c9aa75588c679a8ae151951fa00f001b>

  
You will just need to set "similarity": "boolean" on properties. This is available in elasticsearch 5.4.0 +
