Google’s official client for Mac OS, “Backup And Sync” is no more. It has been replaced by “Google Drive” now. One problem is that the new approach exposes files as a Network Drive. That for some reason isn’t indexed by Spotlight. So, you can no longer search for the Google Drive files via Spotlight, unless you re-enable the indexing.
After jumping through multiple non-working solutions, I found one that enables indexing on Google Drive.
# Enable Google Drive indexing and wait for a few minutes for the files to be index $ sudo mdutil -i on /Volumes/GoogleDrive/ # Confirm that indexing is enabled $ sudo mdutil -a -i on
