macOS Sonoma spotlight search does not find applications

Alt-Space to pop-up a search window following by typing the first few letters of an app is a great and quick way to launch applications on macOS without having to have your dock stuffed with all the apps you often use.

But it's stopped working in Sonoma. I've tried all the articles about re-indexing, the command lines tools to disable/re-enable and instruct a rebuild of the spotlight index. Nothing works.

This seems to be something different on Sonoma. Anyone else seeing this?
