If you're a user of both OSX and Microsoft Outlook 2011 (all 0.0001% of us), you've probably run into the problem of your emails, calendar events, etc. spamming your Finder search results.  You're not alone. This is one of those "It's not a bug.  It's a feature" things.

Problem:

OSX indexes everything in your user folder.  We need all of our Outlook items indexed because Outlook uses the OSX index for searching our email, calendar, etc.  However, Microsoft has placed the Microsoft User Data (I'll call it MUD) folder in Documents.  This by itself is not a bad thing.  It makes it easier to backup Outlook with Time Machine, etc.  We just don't need these items returned when we search for documents, etc.

Searches in Finder generally search everything, including system files.  Spotlight excludes system folders, searching only Desktop, Document, Downloads, Movies, Music, and Pictures, and Public.  

Solution:

This solution came from Office 2011 users responding to Microsoft changing the location of the MUD folder in Office 2011 from its previous location in the Library folder.  The reason we want too move MUD to its original home in Library is because Library is now a hidden folder.  By default, Finder does not display results from hidden folders.  Placing the MUD folder in Library prevents Finder from showing results from that folder while still allowing Outlook to search it.

Step 1 - Follow these instructions [edit: link fixed] from a Yahoo! Answers question about moving the Microsoft User Data folder.

Optional Steps:

These two steps set up convenient default searches with Finder.

Step 2 - In Finder, Preferences, General, New Finder window shows, select <your username> from the drop down selector.

Step 3 - In Finder, Preferences, Advanced, When performing a search, select Search the Current Folder from the drop down selector.

Next time you open a new Finder folder, you'll be ready to do a search all of the locations where you might have files.  The Outlook files will be hidden and Outlook will still be able to search my mail, calendar, etc.
