Hi!
Our Documents have a timestamp field and query results are ordered by time.
Is it possible to get a Document by its ordinal number in the query result instead of getting it by exact timestamp
(timestamps may fluctuate) or reading the whole result set into memory for iteration?
\_id does not work for me as it is auto-generated.
Thanks,
Boris

Hi,
I'm not quiet sure I understand the question, but if you are trying to get only the Nth document in your query result, this sounds like you can use the [`from/size`](https://www.elastic.co/guide/en/elasticsearch/reference/2.0/search-request-from-size.html) parameters. Make sure to read about the dangers of and cost of [Deep Pagination](https://www.elastic.co/guide/en/elasticsearch/guide/current/pagination.html) before using this for large N.
In case I misunderstood the question, maybe you can rephrase it a bit and give an example of what you are trying to do.
