It would be nice to be able to retrieve assets sorted by distance in spatial queries, as part of the GeoJSON support of the Assets Discovery Service.

The desired behavior is like that of the $near operator of MongoDB and, ideally, would be added as a parameter to a spatial query like this:

 https://discovery.organicity.eu/v0/assets/geo/search?lat=51.507351&long=-0.127758&radius=10&km=true&type=urn:oc:entityType:trafficstats

, returning the assets sorted by distance to the point on earth passed in 'lat' and 'long' parameters of the query.
