Hello duboiscg,
Thanks for that info and for choosing the Apple Support Communities. If we understand correctly, you are having an issue with using the search feature on your iPhone. If you haven't already, please restart your device as iOS clears cached data and does other system optimizations when you turn your device off and on.
Restart your iPhone
Also, make sure your iPhone is up to date, as the updates contain stability fixes that can resolve issues like yours, as well as important security updates to keep your iPhone safe.
Update the iOS software on your iPhone, iPad, or iPod touch
Cheers!
