noob question - how do I direct a vassal's research?

I hear people talking about this, directing your vassal's research (which would be very useful). How can you do it?

you go to see them, and click on "let's discuss something else"; this way, you can also tell them (as for any civ with which you share a war, not only vassals) to attack specific cities.
