Scroll API
editScroll API
editWe no longer recommend using the scroll API for deep pagination. If
you need to preserve the index state while paging through more than 10,000 hits,
use the search_after
parameter with a point in time (PIT).
Retrieves the next batch of results for a scrolling search.

Prerequisites
edit-
If the Elasticsearch security features are enabled, you must have the
read
index privilege for the target data stream, index, or index alias.
Description
editYou can use the scroll API to retrieve large sets of results from a single scrolling search request.
The scroll API requires a scroll ID. To get a scroll ID, submit a
search API request that includes an argument for the
scroll
query parameter. The scroll
parameter indicates how long Elasticsearch should retain the
search context for the request.
The search response returns a scroll ID in the _scroll_id
response body
parameter. You can then use the scroll ID with the scroll API to retrieve the
next batch of results for the request.
You can also use the scroll API to specify a new scroll
parameter that extends
or shortens the retention period for the search context.
Results from a scrolling search reflect the state of the index at the time of the initial search request. Subsequent indexing or document changes only affect later search and scroll requests.
