Toolbar button: run search-->specific collection name?

ok i am getting closer to setting up a makeshift 'virtual folder' setup. i just need a quick and easy way to update the collection(s). how could i make a button that would run a saved search and output it to a specific collection?

and ideally in the background so there arent windows popping up all over the place.

Something like in this thread should do it: ... collection

I think the Find command has a QUIET argument which will stop it opening any windows at all. Have a look in the manual for the list of arguments you can give it if that doesn't work.
