I am using [scroll](https://www.elastic.co/guide/en/elasticsearch/reference/6.8/search-request-scroll.html) to fetch docs from elasticsearch, modify them, and reindex them. I have read everywhere and it is mentioned [here](https://www.elastic.co/guide/en/elasticsearch/guide/1.x/scan-scroll.html) and [here](https://discuss.elastic.co/t/clearing-a-scroll-during-scan-and-scroll/42080/2) that each subsequent request sends different scroll\_id. But I don't see that happening. I get the same scroll\_id which I got from the first request. Have I misunderstood anything?

This is possible, the docs are a bit misleading in suggesting that it's _always_ different as there are situations where you might get the same one back. The `scroll_id` is a completely opaque internal identifier, don't try to read any meaning into it 🙂

But I have never found the different scroll\_id. Could you give me two different scenarios?

No, it's an implementation detail. Why does it matter to you?

I am fetching docs from elasticsearch using scroll. I need to know which scroll\_id to pass in request body.

As per the docs you linked, you must always pass the scroll ID from the previous response.

Thanks. That seems a safe approach.
