Ever get this error when trying to add a content source in SharePoint Search?
If you enter http://sharePoint.com/sub-site/default.aspx and select "Crawl only the SharePoint site of each start address" then SharePoint will crawl from the top-level site of the given URL entered. Here SharePoint will crawl from http://sharePoint.com/ and all its sub-sites.
