Calendar search

I copied my reply on another post, because I saw this one first and wanted to come back.

I was having the same issue for over 2 weeks, very frustrating, but like you, I couldn't find anything recent about it. I've restarted phone, done a hard reboot and updated apps - none worked. Today I hunted again, found another suggestion online so I tried it and it worked!!

Go to your iCloud settings and turn off Calendars, choose "Keep on iPhone" - mine took 1-2 minutes to actually turn it off. When I went to calendars, search worked. I did a hard reboot, went back into calendars, search still worked.

Went to iCloud, turned Calendars back on, choose "Merge" - again took 1-2 minutes to turn on. Search worked.

I did another hard reboot, opened calendar, and the calendar displayed was January 2021 (it's October 2022). Search works but several duplicated entries (in shared calendars w/other apple users only) - at the bottom next to "Calendars" it was showing the "working" symbol. I have several shared calendars, some with other apple users, and some through google - it took over an hour for it to stop showing the "working" symbol.

Hope this helps y'all! :)

Hard reboots make me feel better, don't come at me, I don't know if they help, I'm not a tech person.

There is a limit in the Calendar search function on the iPhone that restricts you to only the past year. Are you expecting to see results that are within the year?

I’m having the same problem. Also can’t find iMessage groups
