如何从弹性搜索中获取条件数据

Question

Currently, my ES data is similar to-

 {
      ..............
      ..............
      "centers" : [

        .................
        .................
        {
          "code" : "ABCA",
          "name": "first_code",
          "level" : 0
        },
        {
          "code" : "XYZX",
          "name": "second_code",
          "level" : 1
        },
        {
          "code" : "XYZX",
          "name": "third_code",
          "level" : -1
        },
        {
          "code" : "QWERTY",
          "name": "fourth_code",
          "level" : 2
        },
        .................
        .................

      ],
      ..............
      ..............

}

And I want to filter records with the condition like this-

filter records where code = "ABCA" and code="XYZX" with additional filter code.level(ABCA) < code.level(XYZX)

Expected O/p:

    {
      "code" : "ABCA",
      "name": "first_code",
      "level" : 0
    },
    {
      "code" : "XYZX",
      "name": "second_code",
      "level" : 1
    }

Is this possible?
