		sort 演算子の利用方法は sort:<field>.<order> になります。
		<order> は asc または desc で昇順・降順を指定できます。
		たとえば、Fess を含むドキュメントでサイズの降順にソートしたい場合、次のように入力します。
		<pre>Fess sort:content_length.desc</pre>
		標準で利用可能なフィールドは created, content_length および last_modified 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。

## WebSockets client { #websockets-client }

### In production { #in-production }

In your production system, you probably have a frontend created with a modern framework like React, Vue.js or Angular.

And to communicate using WebSockets with your backend you would probably use your frontend's utilities.
