I need to fetch nearest distinct locations from my index  
Here is my mapping

```auto
{
	"properties": {
		"id": {
			"type": "keyword"
		},
	     "location_name": {
                  "type": "keyword"
              },
             "post_location": {
                   "type": "geo_point"
             },
	}
}

```

We are saving so many posts on same location just like  
Suppose  
"The White House" contains 100 posts  
"Washington National Cathedral." contains 50 posts  
"Jefferson Memorial" contains 20 posts  
etc

I need to get only unique locations rather than their posts. but order of the locations should be according my geo locations.

I am applying following query

```auto

POST /posts/post/_search?size=0
{
   "sort": [
              {
                "_geo_distance": {
                  "post_location": [
                    46,
                    24
                  ],
                  "order": "asc",
                  "unit": "km"
                }
              }
            ], 
  "aggs": {
    "top_tags": {
      "terms": {
        "field": "location_name",
        "size": 100
       
      },
      "aggs": {
        "top_sales_hits": {
          "top_hits": {
            "sort": [
              {
                "_geo_distance": {
                  "post_location": [
                    46,
                    24
                  ],
                  "order": "asc",
                  "unit": "km"
                }
              }
            ],
            "_source": false,
            "size": 1
          }
        }
      }
    }
  }
}

```

Good thing is that it gives my unique locations in bucket  
**but bad thing is order of the locations is not according to my geo location.**
