| 语法 | IDX.REBUILD name |
| 分组 | index |
| 参数个数 | 2 |
| 起始版本 | 3.0.0 |
| 标志 | write, extension |
| 复杂度 | Vector indexes only (tombstone compaction). O(V_live * ef_construction * M * dim) distance evaluations, on every shard, synchronously — the most expensive verb in the extension surface |
| Redis 兼容性 | kevy-only: no Redis analogue — RediSearch handles HNSW deletes internally and exposes no rebuild verb |
