iCal: Unable to find events created prior to 10.4.2 update

After updating to Mac OS X 10.4.2, you may not be able to find iCal 2.0.2 events that were created prior to updating when using the search function in iCal.

When you search for a particular event in iCal, iCal won't display the event in its search results, but you can find the event by browsing to the appropriate day in an iCal calendar or by using Spotlight.

Solution

1. From the iCal File menu, choose Backup Database.
2. Quit iCal.
3. Navigate to ~/Library/Application Support/iCal/Sources.
4. Open each folder in the Sources folder and remove the file named "Index."
5. Open iCal; it will re-index your events.
