sharepoint - Sharepoint 内容查询 Web 部件选择性子站点

Question

尊敬的 SharePoint 专家，

我想在 SharePoint 2013 中创建一个名为“最新上传”的内容查询 Web 部件：

 1. i created the web-part:
 2.in query  source: i selected --> Show items from the following site
 and all sub-sites: i chose a site.
 3.what i need to do is to exclude some of the folders or sub-sites that the query is retrieving data from.

**How can i accomplish that?**
