Distinct value in the query response and not distinct count

Elastic Stack Elasticsearch

I have a use case of getting distinct Values in output, A brief description of the problem is:

The query used:

GET/index_name/type_name/_search
{
    "aggs" : {
        "Country" : {
            "terms" : { 
                "field" : "location.City.keyword",
                "size": 10
            }
        }
    }
}

The output seen:

 "aggregations": {
    "Country": {
      "doc_count_error_upper_bound": 10,
      "sum_other_doc_count": 878,
      "buckets": [
     {
          "key": "PICO RIVERA",
          "doc_count": 8
        },
        {
          "key": "SAVANNAH",
          "doc_count": 8
        }
      ]
    }
  }
}

Now, what I expect is:
this result coming in source value, so that I can process it in the UI; I dont require the count at all, just the distinct value.

" SELECT DISTINCT(City) FROM TABLE"


and NOT


"SELECT COUNT(DISTINCT City) FROM TABLE"

Any pointer is highly appreciated.

Thanks
