Currently you can enjoy ‘Google Suggest Search’ function only when you go directly to http://www.google.com, or type http://www.google.com into your browser’s address field; either way, you’ll be back using ordinary Google search without Google Suggest. Or else, clicked on the link Go to Google.com on Google font page. As you type into the search box, Google Suggest guesses what you’re typing and offers suggestions in real time. Sometimes, you will be getting funny Google Suggest Search based on keywords and sentences.
It features the auto-completion search tool to suggests some popular search results to you while you are typing to search. This is to let you know what the other is searching for.
