在 head Stack Overflow 中有这个标签:
<link rel="search" type="application/opensearchdescription+xml" title="Stack Overflow" href="/opensearch.xml">
我想知道它是做什么的，它是否与 SEO 相关？
我可以找到这个报价:
Provides a link to a resource that can be used to search through the current document and its related pages.
这有点神秘。谁在寻找？盲人？谷歌机器人？
这是文件的内容:
<OpenSearchDescription xmlns="http://a9.com/-/spec/opensearch/1.1/" xmlns:moz="http://www.mozilla.org/2006/browser/search/">
<ShortName>Stack Overflow</ShortName>

<Url type="text/html" method="get" template="http://stackoverflow.com/search?q={searchTerms}"/>
</OpenSearchDescription>
这是 wikipedia opensearch 上的页面指出:
OpenSearch is a collection of technologies that allow publishing of search results in a format suitable for syndication and aggregation. It is a way for websites and search engines to publish search results in a standard and accessible format. OpenSearch was developed by Amazon.com subsidiary A9 and the first version, OpenSearch 1.0, was unveiled by Jeff Bezos at the O'Reilly Emerging Technology Conference in March, 2005. Draft versions of OpenSearch 1.1 were released during September and December 2005. The OpenSearch specification is licensed by A9 under the Creative Commons Attribution-ShareAlike 2.5 License.
这对我来说仍然太神秘了。

关于搜索值
rel 属性的搜索值给出了一个资源链接，可用于搜索当前文档及其相关页面。
关于rel属性
rel 属性指定当前文档和链接文档之间的关系。仅在存在 href 属性时使用。
这个链接说明了一切。
