追加情報（この場合は追加のバリデーション）を入れられる `Annotated` ができたので、`Annotated` の中に `Query` を追加し、パラメータ `max_length` を `50` に設定します:

{* ../../docs_src/query_params_str_validations/tutorial002_an_py310.py hl[9] *}

デフォルト値は引き続き `None` なので、このパラメータは依然としてオプショナルです。

しかし、`Annotated` の中に `Query(max_length=50)` を入れることで、この値に **追加のバリデーション** をしたい、最大 50 文字にしたい、と FastAPI に伝えています。 😎
