I note that since 7.0, scroll is deprecated in deep pagination from the document
But the document also said : the scroll API can be used to retrieve large numbers of results (or even all results) from a single search request.
I have some confusions about this:
- What's the difference between retrieve large numbers of results and deep pagination?
- When hits is more than 10000, why search_after can be more efficient when preserve state?
- Can we use Search_After API for retrieve large numbers of results?
