		sort 연산자는 지정된 필드 이름으로 문서를 정렬합니다.
		sort 연산자의 사용 방법은 sort:&lt;field&gt;.&lt;order&gt;입니다.
		&lt;order&gt; 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.
