**FastAPI** erstellt für Sie das Objekt vom Typ `BackgroundTasks` und übergibt es als diesen Parameter.

## Eine Taskfunktion erstellen { #create-a-task-function }

Erstellen Sie eine Funktion, die als Hintergrundtask ausgeführt werden soll.

Es handelt sich schlicht um eine Standard-Funktion, die Parameter empfangen kann.

		sort 연산자의 사용 방법은 sort:<field>.<order>입니다.
		<order> 는 asc 또는 desc 오름차순 · 내림차순을 지정할 수 있습니다.
		예를 들어, Fess를 포함한 문서 크기의 내림차순으로 정렬하려면 다음과 같이 입력합니다.
		<pre>Fess sort:content_length.desc</pre>
		기본으로 사용 가능한 필드는 created, content_length 및 last_modified됩니다.
		설정에서 지정하는 필드는 변경할 수 있습니다.
	</dd>
	<dt>AND검색</dt>
	<dd>
		AND 연산자는 선택적 연결 연산자입니다.
		AND 연산자는 지정한 검색어를 모두 포함한 문서와 일치합니다.
		예를 들어, Fess과 CodeLibs를 포함하는 문서 검색하려면 다음과 같이 입력합니다.
