IDX.ADVISEThe declarations refused queries have been asking for, most-refused first — each rendered as the command that would serve it.
| Syntax | IDX.ADVISE |
| Group | index |
| Arity | 1 |
| Since | 4.2.0 |
| Flags | readonly, extension |
| Complexity | O(observed families); the refusal log is bounded (128 families, least-refused evicted) and cleared on every catalog install |
| Redis compatibility | kevy-only: no Redis analogue — the refusal log turns 'no such index' into the declaration that would have served the query |
