schema.org - 启用 Google 附加链接搜索框

Question

我想为网站启用 Google 附加链接搜索框。重点是它的自定义搜索页面是通过哈希片段实现的，所以 JSON-LD 数据片段是这样的:

<script type="application/ld+json">
  {
  "@context": "http://schema.org",
  "@type": "WebSite",
  "name" : "my site",
  "alternateName" : "example.com",
  "url": "http://www.example.com/",
  "potentialAction": {
    "@type": "SearchAction",
    "target": "http://www.example.com/Search/#!/Keyword-{search_term_string}",
    "query-input": "required name=search_term_string"
  }
}
</script>

当 Google 尝试从这部分“required name=search_term_string”提取信息以显示附加链接搜索框时，遇到了问题:

:   http://schema.org/True
valueName:  missing and required

我怀疑 Google 可能只是期望在查询字符串中搜索字符串，而不是哈希片段，除了重定向之外，您还有什么建议？

感谢@unor，我找到了解决方案，所以最终的代码是这样的:

<script type="application/ld+json">
        {
          "@context": "http://schema.org",
          "@type": "WebSite",
          "name" : "example",
          "alternateName" : "example.com",
          "url": "http://www.example.com/",
          "potentialAction": {
            "@type": "SearchAction",
            "target": "http://www.example.com/Search/#!/Keyword-{search_term_string}/",
            "query-input": {
        		"@type": "PropertyValueSpecification",
        		"valueRequired": true,
        		"valueMaxlength": 100,
        		"valueName": "search_term_string"
    		}
          }
        }
</script>
