I am currently using `multi_match` to search nested datatypes.

I want to find the index of `shortreview` which matched my query.  
For example, if query matched `""" review_ccc """` of my `review` field, return 2.

my purpose is to find `reviewId` of `shortreview` or `review`. Because `reviewId` will be placed in the same order with `shortreview` and `review`, I need to find the index of the match.

```auto
GET recpost_test/_search
{
  "from": 0,
  "size": 2,
  "query":{
    "multi_match": {
      "query" : "This is what I want to find!",
      "analyzer": "my_analyzer", 
      "type": "best_fields", 
      "fields" : [
        "itemname",
        "review",
        "shortreview^2"]
        
    }
  }
}

```

Here's the simplified version of query result

```auto
{
  "took" : 12,
  "timed_out" : false,
  "_shards" : {
    "total" : 1,
    "successful" : 1,
    "skipped" : 0,
    "failed" : 0
  },
  "hits" : {
    "total" : {
      "value" : 58,
      "relation" : "eq"
    },
    "max_score" : 19.384338,
    "hits" : [
      {
        "_index" : "recpost_test",
        "_type" : "_doc",
        "_id" : "202",
        "_score" : 19.384338,
        "_source" : {
          "reviewId" : [
            "1",
            "2",
            "3"
          ],
          "review" : [
            """ review_aaa """,
            """ review_bbb """,
            """ review_ccc """
          ],
          "shortreview" : [
            """ shortreview_aaa """,
            """ shortreview_bbb """,
            """ shortreview_ccc """
          ],
          "itemname" : [
            "item_a",
            "item_b",
            "item_c"
          ]
        }
      }
    ]
  }
}

```
