Cant search events in my calendar

I found this answer on another thread.

“I was just on the phone with Apple support about this same issue and here is the fix that they gave me that worked: Settings>Mail>Account (select the correct account)>Calendar

then toggle OFF calendar. It asks if you want to delete the account and you accept. After about a minute, toggle it back on, and the calendar entries will start repopulating, and the search function will start working. Depending on how many calendar entries you have, it will take a while to update, but I have thousands and it updated in less than one hour. Search function works again.”
