set Spotlight to give Dictionary Definitions after the Top Hit Entry?

In Snow Leopard when looking at something in Spotlight, after the Top Hit Entry there was the Dictionary Definition. Now I installed Lion and the Definition (or Look Up) entry is at bottom.

How can I change Spotlight Preferences in order to return the Dictionary Definition after the Top Hit (At the very first entries?)

Tried to change the Spotlight Preference in the System Preferences Panel, but there isn't any Dictionary Entry...

Thanks.
