首先创建两个站点,主站点名字叫 Search, 在它下面有一个子站点, 名字叫Search_111。
 
在主站点的 default page中，SearchBox有三个选项:

• All sites:http://localhost:6325/_layouts/OSSSearchResults.aspx?k=c&s=All Sites
• This site: Search:http://localhost:6325/_layouts/OSSSearchResults.aspx?k=c&cs=This Site&u=http://localhost:6325
• People:http://localhost:6325/_layouts/OSSSearchResults.aspx?k=c&s=People

在主站点的List中：

在Shared Documents list中, 他有4个选项.

• All sites:http://localhost:6325/_layouts/OSSSearchResults.aspx?k=c&s=All Sites
• People:http://localhost:6325/_layouts/OSSSearchResults.aspx?k=c&s=People
• This site: Search:http://localhost:6325/_layouts/OSSSearchResults.aspx?k=c&cs=This Site&u=http://localhost:6325
• This List:Shared Documents:http://localhost:6325/_layouts/ OSSSearchResults.aspx?k=c&cs=This List&u=http://localhost:6325/Shared Documents

在子站点的 default page中.

• All sites:http://localhost:6325/_layouts/OSSSearchResults.aspx?k=c&s=All Sites

• This site: Search_111:http://localhost:6325/MMM/_layouts/ OSSSearchResults.aspx?k=c&cs=This Site&u=http://localhost:6325/MMM

• People:http://localhost:6325/_layouts/OSSSearchResults.aspx?k=c&s=People

在子站点的Task List 中的选项如下：

• All sites:http://localhost:6325/_layouts/OSSSearchResults.aspx?k=c&s=All Sites
• This site: Search_111:http://localhost:6325/MMM/_layouts/ OSSSearchResults.aspx?k=c&cs=This Site&u=http://localhost:6325/MMM
• People:http://localhost:6325/_layouts/OSSSearchResults.aspx?k=c&s=People
• This List:Task:http://localhost:6325/MMM/_layouts/OSSSearchResults.aspx?k=c&cs=This List&u=http://localhost:6325/MMM/Lists/Tasks

 所以，我猜测他在使用Url传递参数的时候，有两个规则：

Rule1:所有的 search box 包含三项, People, All sites 和 This Site: site name. 如果是 People 或 All sites, 参数为 k=keyword 和s= the scope(All sites or People).如果是This Site: site name，参数为 k=keyword, cs=This Site, u=current site's url.
 
Rule2: 如果当前是在一个List里面,他将包含另外一项, This List: List name. 参数为 k=keyword, cs=This List, u=current list's url.

但是在List里面没有Url这一项，

一些 list's 属性.

我发现他有两个属性, DefaultViewUrl 和 Title, 所以我们可以通过这两个属性把它拼出来.
