<Url type="text/html" method="GET" template="https://www.google.com/reader/view/#search">
<Param name="" value="{searchTerms}"/>
// {searchTerms}是固定的，这个就是在搜索栏里输入的内容
</Url>
<SearchForm>https://www.google.com/reader/view/</SearchForm>
</SearchPlugin>

想问问这里该怎么写
<Url type="text/html" method="GET" template="https://www.google.com/reader/view/#search">
<Param name="" value="{searchTerms}"/>

求指教
