After Apple's new iOS 26 update, many iPhone users began to face a search error in the Calendar. It has been claimed to be a pest for those who send calendars day in and day out for various meetings, events, and reminders, as it has become a real pain for them.

What's Wrong with It?
Most users report that if they search for some keyword in the Calendar app after updating to iOS 26, it does not show old events or appointments, whereas, in other cases, not even recent events are showing in the search, and most users are finding all of such events by manually browsing. This loss of time and disruption in work is distorting users.
What Is It Affecting in Adobe?
The obstruction has turned into a hurdle for business, project managers, students, and professionals who are constantly referring to old events. Several discussions are brewing around Apple Forums, Reddit, and tech communities.
Possible Cause
This would seem to be a bug in iOS 26, so the people who are getting affected are impeding the search indexing in the Calendar app. Some users had tried restarting their iPhones, disabling iCloud, and then re-enabling iCloud sync, but nothing worked in their favor.
Response From Apple
But, then, it probably couldn't be putting it down; judging by the huge number of people reporting issues with it, it should not take too long to release a fix or update.

Alternatives for Users
For the time being, users could:
Manually browse for old events
Use Google Calendar instead of iCloud Calendar (where search still works)
Report the issue to Apple Support.
This iOS 26 calendar search bug has troubled a lot of users on the iPhone. It should provide a permanent remedy for this. They will have to wait until it resolves this, while having some other workarounds to follow in the meantime.
