ES 6.x : multi indices or one index with field type?

Elastic Stack Elasticsearch

Hi,
we are migrating to ES 6.x so we are redesigning our schemas.
I am wondering which is better for performance ? to have multiple an index for each type or to create one index and add a new type field.

I know that if we will put all the types in one index that would mean that elasticsearch will process all the docs. so this might mean lower performance.

The best answer we can give you is for you to test it yourself.
There are a number of variables we don't know about that make it difficult to impossible to answer this sorry!
