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

| Since | 1.0.0 |
| Flags | write |
| Complexity | O(log N + C) — the seeked nine-cell fetch, same as GEORADIUS; the anchor lookup is O(1) |
| Redis compatibility | differs: the destination is written on its own shard, so a STORE across shards is not atomic with the search |
