Hi,
Just checked, but I’m getting results as I’m typing (on the main site): http://i.imgur.com/cvpIGxO.png
I see however one javascript issue in the console, coming from one of the theme javascript files (smoothscroll.js): http://i.imgur.com/96K0qvf.png
That can cause blocking javascript errors, and possibly the failure of the search script as well, it’s definitely worth investigating.
