    The `Union` in `Union[str, None]` will allow your editor to give you better support and detect errors.

## Additional validation

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

### Import `Query` and `Annotated`

To achieve that, first import:

* `Query` from `fastapi`

	// didn't support ALPN. We used not to enforce protocol overlap, so over

	// expected to accept connections from "http/1.1" clients. See Issue 46310.
