How to group results in elasticsearch?

Question

I am storing Book Titles in elasticsearch and they all belong to many shops. Like this:

{
    \"books\": [
        {
            \"id\": 1,
            \"tit

I have the same problem but the best solution that I have found is change the mapping. You can convert the mapping to that the field "store" will be of type nested. This is because you have an relation many to many. In that way you can apply sorting, pagination. I hope to help.
