I had a registry tweak which allowed for me to type a bunch of words (with spaces between them) into the URL bar and it would do a google search on those words

Create a bookmark. Doesn't matter what, as you're going to edit all of it. Pull up the properties on the bookmark. I believe you have to go through the bookmark manager to get to this. Change the location to ``http://www.google.com/search?hl=en&ie=UTF-8&oe=UTF-8&q=%s''. Set the keyword to `g'. Edit the rest of the stuff as you see fit. Close out all the bookmark editing stuff. Now type into the URL bar ``g all the words you want to search for''.

Actually, the UTF-8 part may not work right under Windows. Just do a regular search from Google's front page and replace that stuff with whatever it uses. It should be obvious.
