Google Map Instant Search

Google Map Instant Search with simple JQuery and j-son script, by using Google's API and by using instant search function keyup(function(e))

Instant search shows results as you type. It is a faster way to search as your results nearly always appear before you have finished typing.

As you type into a search bar it starts recommending locations based on what you are typing and centre on the map on that location. The recommended locations appear beside the search box. The map will nearly always centre on your desired location before you have actually typed in the entire name of the location.
