allinanchor: - Conducts a search based on keywords used strictly in the anchor text, or linking text, of third party sites that link to the web pages returned by the Google search.
基于严格的锚文本或链接文本中的关键字,或链接到由Google返回的网页的第三方网站的搜索。
As an example, an ID on an XHTML element is used for linking within a document — and this is similar to how an anchor name within an HTML document can be used for internal links.
例如,使用XHTML元素的ID在文档内进行链接——这种方式类似于在HTML文档中使用锚点名称进行内部链接。
