Joining you here to offer additional help with the customer search bar, SPELLC.

I tried looking for a specific job using the steps you shared and it has worked on my end. 

We have a tool that can fix some of the most common errors and unexpected results when working in the program. This includes screen and display issues in certain pages. 

Here's how to use it: 

1. Close QuickBooks and download the most recent version (1.5.0.0) of the QuickBooks Tool Hub.
2. Open the file you downloaded (QuickBooksToolHub.exe). You can look it up in your Downloads folder or in the location you selected when you downloaded it.
3. Follow the on-screen steps to install and agree to the terms and conditions.
4. Once done, double-click the icon on your Windows desktop to open the tool hub.
5. Once opened, look for Program Problems, then select Quick Fix my Program.
6. Start QuickBooks Desktop and open your data file.

Once done, log back in and check if the search feature is working back again. Let me share these articles for additional details:
