I personally wouldn't be against migrating that question. Configuring the Windows Search Service on a file server or Terminal server used by many users is something that an administrator may want/need to do.
The way the question is written doesn't seem to be purely about a single end-user. I am not sure if there is an answer though. A correct answer may actually come from stackoverflow. I am not entirely sure if it is even possible without writing a new filter to for the search service (http://msdn.microsoft.com/en-us/library/bb318649(VS.85).aspx) on 2008.
