Google's Newest Search Tool: Google Suggest
Google's newest search tool is Google Suggest. The screen looks just like Google, but when you start typing, Google suggests search terms and shows how many results there are. For example, as "election" is typed into the search box, a drop down menu appears with possible searches that start with election: election results, election, election 2004.
If you like Google Suggest, you might want to try this dictionary that suggests words, along with their meaning, as you type.
