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

Spotlight Preferences

Exclude certain folders from getting indexed:
