Google introduced Wednesday an instant search feature that would surely save users’ time.

Marissa Mayer, vice president of Google’s user experience, said at a press release that a new searching process on the world’s largest search engine would start searching as you type, not after you type.

The new search feature would try to figure out what the user is searching as the user type the letters of his query on the search box. Search results would be based on your past search history.

For example, the user have browsed Google searching for “weather” before, and now, back on the search box and typed the letter “w”. Google would speculate that the user is searching for the word “weather’” again; the search engine would try to display results that have something to do with weather.

Mayer said on the press release held at the San Francisco’s Museum of Modern Art that the average Google query would take about 15 seconds to type the word and would take about 300 milliseconds to process. The new search feature of Google is designed to reduce that time.

She said that they think that this new feature would help users save two to five seconds per query, or 11 hours for every passing second.

Greg Sterling, an analyst for Sterling market Intelligence, said that the new feature makes searching more interactive, and that power users would really appreciate the upgrade.

Sterling also said that Google is now developing a version of the instant search for mobile devices, especially for smartphones. He said that, that step might have the biggest impact because of the fewer keystrokes, making mobile search more widely used.

Google is also happy unveiling its new major milestone reached recently. Google users now reached one billion per week.
