| Complexity | O(log N + C) — up to nine neighbour ranges, each a seeked slice of the score tree; C = members inside the matched geohash cells (the block bound now prunes iteration too, not just distance maths) |
| Redis compatibility | differs: STOREDIST is accepted and ignored on the read-only form; COUNT 0 is an error |
