O FastAPI CLI recebe o caminho para o seu programa Python (por exemplo, `main.py`), detecta automaticamente a instância de `FastAPI` (comumente nomeada `app`), determina a forma correta de importação e então a serve.

Para produção, você usaria `fastapi run`. 🚀

		sort field sorts documents by a specified field name. The format is
		"sort:&lt;field&gt;.&lt;order&gt;", where &lt;order&gt; is asc or
		desc. If you want to find documents which has "Fess" and sort them in
		descending order, you can enter:
		<pre>Fess sort:content_length.desc</pre>
