/// note

FastAPI will know that the value of `q` is not required because of the default value `= None`.

Having `str | None` will allow your editor to give you better support and detect errors.

## Additional validation { #additional-validation }

We are going to enforce that even though `q` is optional, whenever it is provided, **its length doesn't exceed 50 characters**.

This also means that if something changed, it will be **reflected** on the client code automatically. And if you **build** the client, it will error out if you have any **mismatch** in the data used.
