Typing 'paral' into Spotlight suggests 'Pages' instead of 'Parallels Desktop' - how to fix?

If I type any of these in Spotlight (Yosemite): par para parall parallel etc

Parallels Desktop is suggested as the program to launch - which is what I want.

However - if I type 'paral' - what you would think was a good short bet to load the app - it suggests 'Pages.

I endup typing 'paral' a lot as it used to work.

I found nothing on Google.

This makes no sense. How can I fix this?
