IDX.ADVISEThe declarations refused queries have been asking for, most-refused first — each rendered as the command that would serve it.
| 语法 | IDX.ADVISE |
| 分组 | index |
| 参数个数 | 1 |
| 起始版本 | 4.2.0 |
| 标志 | readonly, extension |
| 复杂度 | O(observed families); the refusal log is bounded (128 families, least-refused evicted) and cleared on every catalog install |
| Redis 兼容性 | kevy-only: no Redis analogue — the refusal log turns 'no such index' into the declaration that would have served the query |
