Finding one document of every similar documents group

Elastic Stack Elasticsearch
1

I have an elasticsearch index with many documents. Every group of these
documents contain similar content but not exactly the same.

What is the query that would return only one document of every similar
documents group?

How do you define similar? this could be done either by splitting those
groups to different types, or by using MoreLikeThis

IMHO, I won't index similar documents or I will filter them on the Client side.

To filter on client side, you will have probably to first add to doc a "hashcode" that is set to same value on each similar docs before indexing.

My 2 cents
