Similarity api

[selckin]

Java API client version

8.7.1

Java version

17

Elasticsearch Version

8.7.1

Problem description

The similarity api allows you to create & configure similarities with a specific name/id
https://www.elastic.co/guide/en/elasticsearch/reference/current/index-modules-similarity.html#configuration

For example "my_similarity" and "scripted_tfidf" however in the java api this is not possible:

Current implementation of similarly is not useable and just errors out server side
