| グループ | view |
| 引数の数 | 2 |
| 導入バージョン | 3.0.0 |

| 計算量 | O(sum over leaves of (log N + matched)) — each leaf's cardinality is a real count, so EXPLAIN on a broad leaf costs as much as counting it |
| Redis 互換性 | kevy-only: nearest is FT.EXPLAIN, which returns a query tree rather than per-leaf cardinalities |
