Which field matched query in multi_match search in Elasticsearch?

I have query with multi_match in Elasticsearch:

{
  "query": {
    "multi_match": {
      "query": "luk",
      "fields": [
        "xml_string.autocomplete",
        "state"
      ]
    }
  },
  "size": 10,
  "fields": [
    "xml_string",
    "state"
  ]
}

It works great, result returns expected value: 

{
  "took": 2,
  "timed_out": false,
  "_shards": {
    "total": 5,
    "successful": 5,
    "failed": 0
  },
  "hits": {
    "total": 1,
    "max_score": 0.41179964,
    "hits": [
      {
        "_index": "documents",
        "_type": "document",
        "_id": "11",
        "_score": 0.41179964,
        "fields": {
          "xml_string": "Lukas bla bla bla",
          "state": "new"
        }
      }
    ]
  }
}

I've searched a lot, but I am not able to find out which field matched the query(if it was xml_string OR state)

I have found solution: I have used highlight feature and it's working great

This is how my curl looks like:

 curl -X GET 'http://xxxxx.com:9200/documents/document/_search?load=false&size=10&pretty' -d '{
    "query": {
        "multi_match": {
            "query": "123",
            "fields": ["some_field", "another_field"]
        }
    },
    "highlight": {
        "fields": {
            "some_field": {},
            "another_field": {}
        }
    },
    "size": 10,
    "fields": ["field","another_field"]
}'

As far as I know there is no feature for telling you which field has matched the query.

But you can use the explain feature for debugging your query. You only have to add to your query the pamameter &explain=true. With this parameter you will see an explanation for each field of why it is in the result set and you will guess which field matched the query.
