How to run multiple geo_distance filter to get result for each filter separately?

Elastic Stack Elasticsearch

I need result documents based on geo_distance query for points A(lat=3,long=101) and B(lat=5,long=102) separately. one result docs I need corresponding to filter A(lat=3,long=101) and other result set I need corresponding to filter B(lat=5,long=102). I am not able to find the correct query for this. I found the query which provides union of results is like this:

{
  "query": {
    "bool": {
      "should": [
        {
          "geo_distance" : {
                "distance" : "1km",
                "pin" : {
                    "lat" : 3,
                    "lon" : 101
                }
            }
        },
        {
          "geo_distance" : {
                "distance" : "1km",
                "pin" : {
                    "lat" : 5,
                    "lon" : 102
                }
            }
        }
      ]
    }
  }
}

but here my requirement is to get results separately instead of union.

Hi.
Either use the multi-search api to issue two searches in one request or use a single request with a filters aggregation to include the two geo distance filters and use a top_hits aggregation under that to group the results

@Mark_Harwood1 Thanks for providing solution. I am not able figure out how to use top_hits after applying multiple filters. My request query is like

{
  "size": 0,
  "aggs": {
    "messages": {
      "filters": {
        "filters": {
          "g1Filter": {
            "geo_distance": {
              "distance": "0.1km",
              "distance_type": "arc",
              "location.latLong": {
                "lat": 12.93220,
                "lon": 77.6904
              }
            }
          },
          "g2Filter": {
            "geo_distance": {
              "distance": "0.2km",
              "distance_type": "arc",
              "location.latLong": {
                "lat": 12.93220,
                "lon": 77.6904
              }
            }
          }
        }
      }
    },
    "aggs": {
      "top_hits": {
        "_source": {
          "includes": [
            "documentId"
          ]
        },
        "size": 10
      }
    }
  }
}

I am not getting documents groupBy g1Filter and g2Filter. please help me in figuring-out how to do this?

Hi Maulik,
I don’t have access to your data so can’t test but if the geo distance clauses work as a query they should also work as a filter. Do these clauses match anything?
As for the top_hits expression - aggregations can be nested so simply place another “aggs” expression inside your “messages” section and add the “top_hits” clause inside that.
