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. ---
