  @param radius    set the maximum distance in meters.
  @param precision set the precision for ranking (for example if you set
  precision=100, two objects that are distant of less than 100m
  will be considered as identical for "geo" ranking parameter).
  Note: at indexing, geoloc of an object should be set with
  _geoloc attribute containing lat and lng attributes (for
  example {"_geoloc":{"lat":48.853409, "lng":2.348800}})
