    O parâmetro de consulta `q` é do tipo `Union[str, None]`, o que significa que é do tipo `str` mas que também pode ser `None`, e de fato, o valor padrão é `None`, então o FastAPI saberá que não é obrigatório.
    
    /// note | "Observação"
    
    O FastAPI saberá que o valor de `q` não é obrigatório por causa do valor padrão `= None`.

    #### Using `Union` or `Optional`
    
    If you are using a Python version below 3.10, here's a tip from my very **subjective** point of view:
    
    * 🚨 Avoid using `Optional[SomeType]`
    * Instead ✨ **use `Union[SomeType, None]`** ✨.

    ```
    
    Le paramètre de requête `q` a pour type `Union[str, None]` (ou `str | None` en Python 3.10), signifiant qu'il est de type `str` mais pourrait aussi être égal à `None`, et bien sûr, la valeur par défaut est `None`, donc **FastAPI** saura qu'il n'est pas requis.
    
    /// note
    
    **FastAPI** saura que la valeur de `q` n'est pas requise grâce à la valeur par défaut `= None`.
