How to save One index field into another index?

Elastic Stack Elasticsearch
1

I want to save SMS data in another field because I am getting the same SMS three times that's why to avoid duplication I used document_id that is overriding the old with a new one but problem is that I am getting SMS data in the first message after that I am getting empty field. SMS data is overridden by an empty field. So I want to save SMS data in the new index before overriding it.

How I can achieve this?

Thanks.

You need to handle that outside Elasticsearch, there's nothing native that will do that for you sorry to say.
