Get results with distance filter

Elastic Stack Elasticsearch

Hello ,
I would like to get the results where coordinates are less than 15 km from this point for example: [35.3,-2.5] but I have this error : no [query] registered for [station_location]

my request is :

I am not sure I understand what your question or problem is. Could you please clarify?

I think the query is wrong and Elasticsearch is looking for a query called station_location. Instead you need to place the query geo_distance:

             "filter" : {
                "geo_distance" : {
                    "distance" : "200km",
                    "station_location" : {
                        "lat" : 35.5,
                        "lon" : -2.5
                    }
                }
            }

Thank you very much , it works well,

{
"query": {
    "bool" : {
        "must" : {
            "match_all" : {}
        },
        "filter" : {
            "geo_distance" : {
                "distance" : "10500m",
                "station_location" : "35.5,-2.5"
            }
        }
    }
}

}

one last question how to get with the results the distance?

To get the distance of the document in km:

{
  "_source": "*", 
  "script_fields": {
    "distance" : {
      "script" : {
        "source": "doc['station_location'].arcDistance(params.lat,params.lon) * 0.001",
        "params": {
          "lat": 2.27,
          "lon": 50.3
        }
      }
    }
  },
"query": {
    "bool" : {
        "must" : {
            "match_all" : {}
        },
        "filter" : {
            "geo_distance" : {
                "distance" : "10500m",
                "station_location" : "35.5,-2.5"
            }
        }
    }
}
