Hi Team,

i am trying to experiment on the nested query `https://www.elastic.co/guide/en/elasticsearch/reference/current/nested.html`

I am able to get the query working the way i needed to:

```auto
GET my_index/_search
{
  "_source": "false", 
  "query": {
    "bool": {
      "filter": [
        {
          "term": {
            "_id": {
              "value": "1"
            }
          }
        },
        {
          "nested": {
            "path": "user",
            "query": {
              "bool": {
                "filter": [
                  {
                    "match": {
                      "user.first": "Alice"
                    }
                  },
                  {
                    "match": {
                      "user.last": "White"
                    }
                  }
                ]
              }
            },
            "inner_hits": {}
          }
        }
      ]
    }
  }
}

```

Two questions :

- Are there any performance improvements by using id in the search request apart from the unique document search ?
- Is there a way to get the data in to hits rather than innerhits, read the documentation , couldnt find a example for mapping it back and has performance hit in calculating nested documents on large indexes.
