Ajax search possible?

Hello again,

Nowadays, users are use to get their info without having to click on a button. Is there a way to set up an ajax search so that the map and listing update themselves after let’s say few seconds (parameters to be determined by the admin) after a filter criterion has been changed (location, radius, category selection, etc …) without to have to click on the “search” button?

Thanks for your reply.
