This command is exactly like `GEORADIUS` 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.
|
|
|
|
The position of the specified member is used as the center of the query.
|
|
|
|
Please check the example below and the `GEORADIUS` documentation for more information about the command and its options.

Note that `GEORADIUSBYMEMBER_RO` 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 `GEORADIUS` page for more information.
