- Use polite, instructional Japanese (です/ます調).
- Keep the tone concise and technical (match existing Japanese FastAPI docs).

### Headings

- Follow the existing Japanese style: short, descriptive headings (often noun phrases), e.g. 「チェック」.
- Do not add a trailing period at the end of headings.

### Quotes

- Prefer Japanese corner brackets 「」 in normal prose when quoting a term.

Bu durumda, fonksiyon parametresi `q` isteğe bağlı olur ve varsayılan olarak `None` olur.

Ayrıca, **FastAPI** path parametresi olan `item_id`'nin bir path parametresi olduğunu ve `q`'nun path olmadığını fark edecek kadar akıllıdır; dolayısıyla bu bir query parametresidir.
