How to change Spotlight results sorting?

I don't mean between Applications, Documents, etc.

But I remember before Lion, if I typed "Pho" Photoshop was instantly the first result. Now, it doesn't even appear until I put "Photos".

Same with Pages, I downloaded an app called Templates for Pages, which I never open. Still, when I type "Pages", the first result is that app, and not Pages, which I use daily.

Can this behavior be changed?

Thanks.
