Try creating a new folder on your desktop then send yourself a copy of the documents folder to your desktop.
Copy all visible files to the new folder(keeping an eye on the space to make sure that huge file isn't copied)
Rename it to documents and replace the existing one
Have you tried searching for it from root?
