 * <p>A graph is composed of a set of nodes and a set of edges connecting pairs of nodes.
 *
 * <p>There are three primary interfaces provided to represent graphs. In order of increasing
 * complexity they are: {@link Graph}, {@link ValueGraph}, and {@link Network}. You should generally

Add to `system.properties`:
```properties
web.api.gsa=true
```

After enabling this setting and restarting Fess, check your Fess version's documentation for the specific GSA-compatible endpoint configuration. The primary migration path is to:

1. **Import your GSA configuration** using the method described above
2. **Update client applications** to use Fess's JSON Search API (see [API Reference](#api-reference) section)

    注意：我們在主鍵欄位使用 `int | None`，這樣在 Python 程式碼中我們可以「在沒有 `id` 的情況下建立物件」（`id=None`），假設資料庫在儲存時會「自動產生」。SQLModel 瞭解資料庫會提供 `id`，並且在資料庫綱要中「將該欄位定義為非空的 `INTEGER`」。詳情請見 [SQLModel 文件：主鍵](https://sqlmodel.tiangolo.com/tutorial/create-db-and-table/#primary-key-id)。

* `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 }

    **注意：** 我们为主键字段使用 `int | None`，这样在 Python 代码中我们可以在没有 `id`（`id=None`）的情况下创建对象，并假定数据库在保存时会生成它。SQLModel 会理解数据库会提供 `id`，并在数据库模式中将该列定义为非空的 `INTEGER`。详见 [SQLModel 关于主键的文档](https://sqlmodel.tiangolo.com/tutorial/create-db-and-table/#primary-key-id)。

* `Field(index=True)` 会告诉 SQLModel 应该为此列创建一个 **SQL 索引**，这样在读取按此列过滤的数据时，程序能在数据库中进行更快的查找。

    SQLModel 会知道声明为 `str` 的内容将是类型为 `TEXT`（或 `VARCHAR`，具体取决于数据库）的 SQL 列。
