This is incredibly frustrating. I think I may have found a bug in either Time Machine or Spotlight, or how they work together. Let me explain: First off, let me point out a very very odd behavior. Let's say I open Spotlight in the upper right corner of the screen and type in "bear". I click "Show All" and a Finder window comes up, defaulting to searching "This Mac" and searching "Contents." I switch to search "File Name" instead, and get a few results. Now, I close that Finder window. I click the Finder icon to open a fresh window, and start typing "bear" in the search box, and once again search "This Mac" and "File Name." NOTHING. No results. What the hell??? To make matters worse, Time Machine behavior is absurd. Let's say I have the previous Finder window open that has a few "bear" related files. They're dated December 2007. I run Time Machine and start flipping back..and boom, the bear files vanish. Yet I've only jumped back to May 2008. If the files were on my hard drive the entire time since 2007, why would Time Machine not show them anymore?? Could someone please explain if I'm doing something wrong? Is this a known bug? If it's not a bug, then this is awfully non-intuitive for Apple software.
