// Index mapping for object MyObject
"myobjects": {
    "mappings": {
      "myobject": {
        "properties": {
            "locations": {
            "type": "nested",
            "include_in_parent": true,
            "properties": {
                "geo_coordinates": {
                "properties": {
                  "lat": {  "type": "double" },
                  "lon": { "type": "double" }
                }
              },
  }
[...]
// Index mapping for object Location 
"locations": {
    "mappings": {
      "location": {
        "properties": {
          "geo_coordinates": {
            "type": "geo_point"
          },
        }
      }
    }
The object A looks like this:

var MyObjectSchema = new Schema(
[...]
    locations: {
      type: [{ type: Schema.Types.ObjectId, ref: 'Location', es_schema: LocationSchema.schema}],
      es_type: 'nested',
      es_include_in_parent: true
    },
[...]
)
The object Location looks like this:

var LocationSchema = new Schema(
[...]
  geo_coordinates: {
      type: {
        geo_point: {
          type: String,
          es_type: 'geo_point',
          es_lat_lon: true
        },

        lat: {type: Number, default: 0},
        lon: {type: Number, default: 0}
      },
      es_type: 'geo_point'
  }
[...]
);
My query looks like this:

// POST http://ES-endpoint/locations/_search
{
    "query": {
        "filtered" : {
            "query": {
                    "match_all" : {}
                },
                "filter" : {
                    "geo_distance" : {
                        "distance" : "20000km",
                        "locations.geo_coordinates" : {
                            "lat" : 40,
                            "lon" : -70
                        } }  }  } }}
