所以：

```Python
q: str | None = Query(default=None)
```

...会让参数变成可选，默认值为 `None`，等同于：

```Python
q: str | None = None
```

但使用 `Query` 的版本会显式把它声明为一个查询参数。

然后，我们可以向 `Query` 传入更多参数。本例中是适用于字符串的 `max_length` 参数：

```Python
q: str | None = Query(default=None, max_length=50)
```

Versioning must be explicitly enabled on a bucket, versioning is not enabled by default. Object locking enabled buckets have versioning enabled automatically. Enabling and suspending versioning is done at the bucket level.
