suppose my ES has 10 coordinates stored. now I have drawn a shape which coordinates points are A, B, C, D. Now Es had 10 coordinates, 2 of them are inside this shape. **need a ES query to get those coordinates**. is it possible or I am expecting something terribly wrong.

Are those coordinates in different documents or in one document?

If they are in different documents and they have been indexed as `geo_point`, a `geo_polygon` query should do the trick.

The only thing to mind here is that polygons are not geodesic.

Yes, but you need to make sure that the field `location` is mapped to a geo\_point.

you can get the current mapping with the command:

```auto
 GET /myindex_in_2018-04-25/_mapping/ping

```
