When you search for a user by using the People scope in Microsoft SharePoint Server 2010, you receive two identical results.
This problem is caused by a bug in the SharePoint Server 2010 Search service. This bug causes some document properties to remain even after the documents are deleted from the index. You cannot remove these orphan properties. Therefore, the properties reappear in the search results.
