Do I need to re-index my Volume?
Solution 1:
Open terminal and type:
sudo mdutil -E /
- You will be asked for your password, provide it, as this command requires administrator privileges to run.
- After confirming your Spotlight index will be re-built and your files should appear in the search. ( Depending on the size of your HDD it can take a while )
To turn Spotlight on/off use:
sudo mdutil -i on /
sudo mdutil -i off /
To fine tune your Spotlight settings open System Preferences > Spotlight
