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

ya que usará ese `None` como el valor por defecto, y de esa manera hará el parámetro **no requerido**.

La parte `Union[str, None]` permite que tu editor brinde un mejor soporte, pero no es lo que le dice a FastAPI que este parámetro no es requerido.

///

Luego, podemos pasar más parámetros a `Query`. En este caso, el parámetro `max_length` que se aplica a los strings:
