Looks like this helped me:
- first I removed all selections under System Preferences/ Spotlight/ search results
- restart
- use terminal:
sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.metadata.mds.plist
wait 20s
sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.metadata.mds.plist
sudo mdutil -E /Volumes/*
you should get a message indicating that indexing is enabled.
