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

But the `Query` versions declare it explicitly as being a query parameter.

/// info

Keep in mind that the most important part to make a parameter optional is the part:

```Python
= None
```

or the:

```Python
= Query(default=None)
```

By adding a star, other users will be able to find it more easily and see that it has been already useful for others.
