Questions about nested objects

Elastic Stack Elasticsearch
1

Questions about nested objects:

  1. Can you limit the query response to only those nested objects that have a match?
  2. Is there a way to limit the number of nested object returned in the query response by a fixed number?
  3. Is there a way to page through the nested objects, instead of returning them all together?

All these questions stem from the fact that we might be facing a scenario with a lot of nested objects, and we don't necessarily want to get all of them all the time.

Any help will be appreciated. Thanks!

Take a look at inner hits:
https://www.elastic.co/guide/en/elasticsearch/reference/5.3/search-request-inner-hits.html

It will solve most issues except the last one. There might be something
related to paging inner hits in 5.3. If not, it is definitely an open issue.

Thanks Ivan! This is exactly what I am looking for.
Looks like we can also page by using the "from" and "size" option.
