I noticed some apps missing from Spotlight, so I tried to force a reindex by adding /Applications to the exclusion list, then removing it. Now it's even worse, as none of my apps are indexed. How do I force this the right way?
Launch Terminal, and type or paste the following command:
sudo mdutil -E /
reindex the spotlight database for everything on the computer, (it might take a while)
Terminal may ask you for your password
