Google Instant is part of the company's campaign towards making the search experience faster.
According to the search engine giant, the average search takes about 25 seconds, and about 24 of those tick by while you're either typing keywords or deciding which result to choose.
"Google Instant is a new search enhancement that shows results as you type. We are pushing the limits of our technology and infrastructure to help you get better search results, faster," the company said in a statement.
Google has in the past pushed the "limits of technology" by working on several factors to improve the speed of the server, networking, and browser technologies.
Google's new Instant, however, is an effort to help the human.
The new offering does not require the user to type the complete term or even press 'search'. Besides this, seeing results as you type helps you formulate a better search term by providing instant feedback, Google said.
Just as the user starts typing the first letter, suggestions appear in grey text directly in the search box.
So ultimately what changes in the way you search is that the moment you start typing, results will appear. This means that you had to type a full search term, hit search, and hope for the right results.
Speaking at the launch, Google Vice President of Search Product and User Experience, Marissa Mayer dubbed it "search at the speed of thought."
