使用 Microsoft 搜索 API xrank 搜索结果

可以在 Microsoft Graph 中使用 Microsoft 搜索 API XRANK 表达式,根据匹配表达式中的特定字词匹配项提升项的动态排名,而无需更改与查询匹配的项目。 XRANK 表达式包含一个必须匹配的组件、匹配表达式,以及一个或多个只对动态排名做出贡献的组件,即排名表达式。 必须为有效的 XRANK 表达式指定至少 1 个参数(不包括 n)。 xrank 运算符仅在 SharePoint 中托管的文件上受支持。

XRANK 运算符的使用语法如下:

<match expression> XRANK(cb=100, rb=0.4, pb=0.4, avgb=0.4, stdb=0.4, nb=0.4, n=200) <rank expression>

示例

以下示例显示了一个请求,该请求搜索 SharePoint 中托管的文件并使用 XRANK 运算符 提升指定的搜索结果。
