Tip 36: SharePoint Search Server Name Mappings
This tip is for Microsoft Office SharePoint Server 2007, Search Server 2008, SharePoint Server 2010 and Search Server 2010 Express.
Need to return search results with a different URL than the URL that was crawled by SharePoint? You can do this using a Server Name Mapping in the search settings of SharePoint.
One caveat is that after the mapping is created, a full crawl has to be completed for the new URLs to show up in the results; http://support.microsoft.com/kb/974414.
