* `Field(index=True)` 告訴 SQLModel 應為此欄位建立「SQL 索引」，以便在用此欄位過濾讀取資料時更快查詢。

    SQLModel 會知道宣告為 `str` 的欄位在 SQL 中會是 `TEXT`（或 `VARCHAR`，依資料庫而定）。

### 建立引擎 { #create-an-engine }

SQLModel 的 `engine`（底層實際上是 SQLAlchemy 的 `engine`）是用來「維護與資料庫連線」的東西。

* `Field(index=True)` は、この列に対して SQL のインデックスを作成するよう SQLModel に指示します。これにより、この列でフィルタしてデータを読む場合に検索が高速になります。

    `str` と宣言されたものは、SQL の `TEXT`（データベースによっては `VARCHAR`）型の列になることを SQLModel は理解します。
