Count on Apple to take something that works, and break it.
This problem has been happening since the last macOS update of macOS Crapalina. At first I thought it might be a bad index, but I forced the Spotlight index to rebuild with no luck.
PROBLEM: using Spotlight to find an application won’t find it, instead showing all sorts of other things. It holds true for all apps I tried.
The solution is simple: launch the app manually. Then and only then will Spotlight find it! For low long... I don’t know. Maybe forever, or maybe it expires?
Shown below is Spotlight search on top of the Applications window showing the presence of the application being search for! Nice job, Apple.
UPDATE: Spotlight forgets EVERY DAY, so app search never works for me.
Conjuring up non-existent web pages
It gets worse, and this too is a new behavioral bug.
I often search for my source code files by name to open them directly. What does Spotlight do? Deprioritize the #1 match for the file I want and instead invent a non-existent web page instead.
Apple is so screwed-up these days, unable to even keep basic functionality working. Quality control is an oxymoron with this company, which is now intent on spying on the world.
