I am working with Java Api of elastic search.

Lets say I fetch below mentioned json data from elastic search.

  {
     "id":"123",
      "genres":[{"key":"EN","value":"action"},{"key":"FR","value":"action"}]
    },
    {
      "id":"234",
      "genres":[{"key":"EN","value":"action"},{"key":"FR","value":"drama"}]
    }

I want to slice/filter data on the basis of the value of key property. For example on passing key as EN I want below mentioned data. I have tried nested query but it did not work.

Expected output:

 {
     "id":"123",
      "genres":[{"key":"EN","value":"action"}]
    },
    {
      "id":"234",
      "genres":[{"key":"EN","value":"action"}]
    }

Can this be achieved in elastic search?

    Yes, if your genres field is of nested type, it's possible to do it with a nested inner_hits. This answer might help: stackoverflow.com/questions/32773542/… Commented Feb 7, 2017 at 16:45

  • Unfortunately our code base is 1.4 and this concept is not present in that. Commented Feb 7, 2017 at 17:15
  • You know what to do: upgrade :-) 1.4 is not supported anymore Commented Feb 7, 2017 at 17:15
