How to retrieve just certain amount of docs from a larger query?

Elastic Stack Elasticsearch
1

Hi,

i need to fire a query against larger amount of docs (100.000)
I just need to get back _id under a certain soerting and therefore using
_source filter false, so there is no overhead by gettings _source data.
Nevertheless the response and response processing of course takes a while
caused by the large amount.

Question: Is there a way to to do something like "execute the query, but
just give me the 10 docs before and 10 docs after a certain doc identified
by id" ?

Thx in advance,
Tom

Look into the scan/scroll query

It works like a cursor that iterates through all docs of a query result
