  4. docs/ko/docs/tutorial/query-params-str-validations.md

    `Optional` 부분은 편집기에게 더 나은 지원을 제공하기 위해서만 사용됩니다.
    
    ///
    
    또한 `Query`로 더 많은 매개변수를 전달할 수 있습니다. 지금의 경우 문자열에 적용되는 `max_length` 매개변수입니다:
    
    ```Python
    q: str = Query(None, max_length=50)
    ```
    
    이는 데이터를 검증할 것이고, 데이터가 유효하지 않다면 명백한 오류를 보여주며, OpenAPI 스키마 *경로 작동*에 매개변수를 문서화 합니다.
    
    ## 검증 추가
    
    매개변수 `min_length` 또한 추가할 수 있습니다:
    
    ```Python hl_lines="9"
    {!../../docs_src/query_params_str_validations/tutorial003.py!}
    ```

  8. docs/zh/docs/tutorial/query-params-str-validations.md

    ...使得参数可选,等同于:
    
    ```Python
    q: str = None
    ```
    
    但是 `Query` 显式地将其声明为查询参数。
    
    然后,我们可以将更多的参数传递给 `Query`。在本例中,适用于字符串的 `max_length` 参数:
    
    ```Python
    q: Union[str, None] = Query(default=None, max_length=50)
    ```
    
    将会校验数据,在数据无效时展示清晰的错误信息,并在 OpenAPI 模式的*路径操作*中记录该参​​数。
    
    ## 添加更多校验
    
    你还可以添加 `min_length` 参数:
    
    ```Python hl_lines="10"
    {!../../docs_src/query_params_str_validations/tutorial003.py!}
    ```
    
    ## 添加正则表达式
