Hello TerryReagan, welcome to the Microsoft community, I'll be happy to help you today;
I understand that you are having issues with Search and Indexing on Windows 11;
Initially I recommend that you try the following;
Press Windows key + R and type: services.msc press Enter;
Locate the Windows Search service and double-click on it;
In Startup type, change it to Automatic;
Under Service Status, click Stop and then click Start;
Click Apply and then OK;
Now try rebuilding the index again;
Access the Control Panel;
Click View by: and change to small icons;
Click Indexing Options;
Click Advanced;
Click Recreate;
Restart your PC and check if the problem still persists;;
Hope this helps, see you soon!
