Yeah you're right... I've just noticed that it's not working anymore... I guess I will live with it while waiting for a better solution
The solution is here : https://superuser.com/questions/1663797/google-drive-files-not-appearing-in-spotlight-and-alfred-after-update You have to manually enable Spotlight indexing again. Open a Terminal window and type: sudo mdutil -i on /Volumes/GoogleDrive* Worked for me on MAC OS Big Sur 11.5.2. Just wait 5 min and the files should show up. Of course, you have to add /Volumes/GoogleDrive/MyDrive to your search scope first.
