Hi I am fairly new to ES and need some help.  
I have an index

```auto
{
  "shop_index": {
    "properties": {
      "shop_key": {
        "type": "nested",
        "properties": {
          "shop_id": "keyword",
          "shop_number": "long"
        }
      }
    }
  }
}

```

Now in some cases we are storing some shops with the same shop\_key so same shop\_id and shop\_number, i just need to find these records on ES, i tried with nested aggregation but doesnt give the result also i tried with script "doc['shop\_key.shop\_id'].value + String.valueOf(doc['shop\_number'].value)" but this doesnt return the correct doc\_count for duplicate records.  
Can you suggest something.  
Sorry if the code is bad , i just started with ES 3 days back 🙂 so still lot to learn.
