Move Search Function In Ready Theme

[Bruce - PhosphorMedia]

FYI: Its not super simple to do this as you have to restructure the entire header. Also, you need to keep the search link in the navigation to support smaller devises. We do this on theworkwearstore.com by using the wrapper

<div id="js-open-global-search--tablet" class="column one-twelfth float-right open-global-search--tablet"><span data-rt-icon="j"></span></div>

The code for the navigation bar is located in ReadyTheme -> Navigation Sets -> navigation_bar

I am currently using Iron And Wool ready theme. I would like to place the search function in the global header as opposed to the navbar. Where can I find this in the code?
