## Validaciones adicionales { #additional-validation }

Vamos a hacer que, aunque `q` sea opcional, siempre que se proporcione, **su longitud no exceda los 50 caracteres**.

### Importar `Query` y `Annotated` { #import-query-and-annotated }

Para lograr eso, primero importa:

* `Query` desde `fastapi`
* `Annotated` desde `typing`

    * Objetos JSON (`dict`).
    * Array JSON (`list`) definiendo tipos de elementos.
    * Campos de cadena de caracteres (`str`), definiendo longitudes mínimas y máximas.
    * Números (`int`, `float`) con valores mínimos y máximos, etc.

* Validación para tipos más exóticos, como:
    * URL.
    * Email.
    * UUID.
    * ...y otros.
