I have found that the search function on my Ipad 2 calendar only retreives events within the past 12 months. For medical patient privacy reasons I do not back-up to iCloud. Rather, I back-up locally to Outlook on my PC. I have 10+ years of events saved to my iPad. I transferred all of these events from my Palm device to Outlook and then from Outlook to the iPad. The same goes for Spotlight Search...only events from the past year. I have had the iPad 2 for 6 months and the calendar search only goes back one year from the current date. Is this universal....unique to my device? Is there a solution? Much thanks.
