If no WITH* option is specified, an Array reply of matched member names
If WITHCOORD, WITHDIST, or WITHHASH options are specified, the command returns an Array reply of arrays, where each sub-array represents a single item:
- The distance from the center as a floating point number, in the same unit specified in the radius.
- The Geohash integer.
- The coordinates as a two items x,y array (longitude,latitude).
