O **JSON Schema** na verdade não tem um campo `example` nos padrões. Versões recentes do JSON Schema definem um campo <a href="https://json-schema.org/draft/2019-09/json-schema-validation.html#rfc.section.9.5" class="external-link" target="_blank">`examples`</a>, mas o OpenAPI 3.0.3 é baseado numa versão mais antiga do JSON Schema que não tinha `examples`.

## 技术细节

关于 `example` 和 `examples`...

JSON Schema在最新的一个版本中定义了一个字段 <a href="https://json-schema.org/draft/2019-09/json-schema-validation.html#rfc.section.9.5" class="external-link" target="_blank">`examples`</a> ，但是 OpenAPI 基于之前的一个旧版JSON Schema，并没有 `examples`.

	<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.
