Issue removing search bar in header

I have scoured the forums for help with this and have tried all of the tips and nothing has worked for me so far. I'm trying to get rid of the search bar feature in the header so there is no space between my logo/tagline and the primary menu. I have no use for the search bar. http://as-designed.ml/ Any help would be greatly appreciated. I've spent far too much time on this. :)
