How Google Autocomplete works

When you go to the Google homepage, you’ll most likely know what you’re about to type into the search box – whether you’re checking in on the weather forecast, looking for a business or service, or want to find out where you recognize that actor from. (Unless you’re “feeling lucky,” that is.)You enter a word or a single letter, and Google will populate the search box with a list of “predictions” before you’ve even finished typing.
