How to use geo-location filters in search?

Hi,

Is it possible to use metadata filtering to restrict the results to be within the radius of a geographical point (latitude and longitude)?

For instance, lets say that my index consists of a list of Hotels and I want to find the best match for my semantic vector BUT only within a certain radius of my city. Each hotell might have multiple locations.

Example data:

[{
	"id": "1",
	"metadata": {
		"name": "A great Hotel",
		"locations": [[-77.0364, 38.8951]]
	},
	"values": [-0.031287473, -0.024716083, -0.0017911823, ...]
}
{
	"id": "2",
	"metadata": {
		"name": "Another Great Hotel",
		"locations": [[-77.0364, 38.8951],[-77.0364, 38.8951],[-77.0364, 38.8951]]
	},
	"values": [-0.031287473, -0.024716083, -0.0017911823, ...]
}]

How I imagine a query could look like:

{
    "vector": [0.0040269415, -0.028688831, 0.015932681, -0.02544977,  ...],
    "filter": {
		"locations": {
			"WithinGeoRange": {
				latitude: -77.0364,
				longitude: 38.8951,
				radius: 20
          }
		}
	}
}

I think you could just filter in your script when you receive the response ?
