<h2>검색방법</h2>
<dl>
	<dt>필드 지정 검색</dt>
	<dd>
		필드 이름 뒤에 콜론 :에 지정된 모든 필드에서 검색 할 수 있습니다.
		예를 들어, 문서의 title 필드에서 Fess가 포함 된 문서를 검색하려면 다음과 같이 입력합니다.
		<pre>title:Fess</pre>
		기본으로 사용 가능한 필드는 url, host, site, title content,
		content_length, last_modified 및 mimetype입니다.
		설정에서 지정하는 필드는 변경할 수 있습니다.
	</dd>
	<dt>정렬</dt>
	<dd>
		sort 연산자는 지정된 필드 이름으로 문서를 정렬합니다.
		sort 연산자의 사용 방법은 sort:&lt;field&gt;.&lt;order&gt;입니다.

<h2>検索方法</h2>
<dl>
	<dt>フィールド指定検索</dt>

		フィールド名の後にコロン : で指定した任意のフィールドで検索することができます。
		たとえば、ドキュメントの title フィールドで Fess を含むドキュメントを検索する場合は次のように入力します。
		<pre>title:Fess</pre>
		標準で利用可能なフィールドは url, host, site, title, content,
		content_length, last_modified および mimetype になります。
		設定で指定するフィールドは変更することができます。
	</dd>
	<dt>ソート</dt>
	<dd>
		sort 演算子は指定したフィールド名でドキュメントをソートします。
		sort 演算子の利用方法は sort:&lt;field&gt;.&lt;order&gt; になります。
