Smart Folder stopped working

Question

When I first installed Tiger, I created a Smart Folder to display all the Presentations on my Powerbook. A simple "Kind: Presentations" Smart Folder did the job perfectly, displaying all Keynote and PowerPoint presentations.
Recently, this Smart Folder stopped working properly - only giving 4 or 5 results instead of the 50-or-so it returned previously. Using Spotless, I completely rebuilt the Spotlight index.
Now, my Smart Folder only displays Apple Keynote documents - no PowerPoint presentations.
Has Apple redefined the results "Kind: Presentations" returns, so as only to return Keynote results? Or is something wrong here?
(Edited to add: A Spotlight "Kind:Presentations" returns both PowerPoint and Keynote files, but not a Smart Folder!)

Answer 1

I've seen people complaining about Word docs not getting classified correctly, it seems to be a result of something odd with the new MicroSoft Office mdimporter. It wouldn't surprise me at all that the peculiarity extends to presentations as well. See this thread:

You might try this:
Bring up a new Find window, in the criteria drop down window select Other, then in the dialog box select Raw Query. In the Raw Query field paste in this:
(kMDItemContentTypeTree = 'public.presentation')
and see if it pulls up the PowerPoint presentations. If so save it as a Smart Folder. If the MS mdimporter has been revised so that it isn't passing correct information to the Spotlight database this may not work. But it is worth a shot.
