Nested Search in ElasticSearch not working?

Question

I want to fetch all the states where country name is "India" . Why I am not able to search nested data with elastic search ?

Exception : nested: QueryParsingException[[userinfo] [nested] nested object under path [country] is not of nested type]; }]

Query I am Executing :

userinfo is the index name and state is the type

        POST /userinfo/state/_search?v
        {
            "query": {
                "nested": {

                   "path": "country",
                   "query": {
                       "match": {
                          "country.name": "India"
                       }
                   }
                }
            }
        }

        ------------------------------
        My Json is for state type : 

        {
                    "_index": "userinfo",
                    "_type": "state",
                    "_id": "35",
                    "_score": 1,
                    "_source": {
                       "id": "35",
                       "name": "County Down",
                       "abbreviation": "DWN",
                       "isDeleted": 0,
                       "country": {
                          "id": "3",
                          "name": "United Kingdom",
                          "abbreviation": "UK",
                          "isDeleted": 0
                       }
                    }
                 }

Try This with match : 

POST /index/type/_search?v
{
    "query": {
        "match": {
           "state.country.name": "India"
        }
    }
}
