GEORADIUSBYMEMBER key member radius m|km|ft|mi [WITHCOORD] [WITHDIST] [WITHHASH] [COUNT count] [ASC|DESC] [STORE key] [STOREDIST key]

Time complexity: O(N+log(M)) where N is the number of elements inside the bounding box of the circular area delimited by center and radius and M is the number of items inside the index.

This command is exactly like with the sole difference that instead of taking, as the center of the area to query, a longitude and latitude value, it takes the name of a member already existing inside the geospatial index represented by the sorted set.

Please check the example below and the GEORADIUS documentation for more information about the command and its options.

Note that is also available since Redis 3.2.10 and Redis 4.0.0 in order to provide a read-only command that can be used in replicas. See the page for more information.
