Sprich:

```Python
q: Union[str, None] = Query(default=None)
```

... macht den Parameter optional, mit dem Defaultwert `None`, genauso wie:

```Python
q: Union[str, None] = None
```

Und in Python 3.10 und darüber macht:

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

... den Parameter optional, mit dem Defaultwert `None`, genauso wie:

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