Replacing Ajax Search

Hey Guys,

So I was talking with Swiftype and their solution would work perfectly, but basically, I need to disable the theme’s ajax search function while leaving the search box enabled/present. From there, embedding the following code in the footer would leverage the search box…can you tell me where i do this in the php files?

<script type="text/javascript">
var Swiftype = window.Swiftype || {};
(function() {
  Swiftype.key = 'EeQjiyzuVo7taNSHZzYs';
  Swiftype.inputElement = '#searchform input#s';
  Swiftype.attachElement = '#searchform input#s';

  /** DO NOT EDIT BELOW THIS LINE **/
  var script = document.createElement('script'); script.type = 'text/javascript'; script.async = true;
  script.src = "//s.swiftypecdn.com/embed.js";
  var entry = document.getElementsByTagName('script')[0];
  entry.parentNode.insertBefore(script, entry);
}());
</script>

<style>
#st-overlay-search-input {
  border: 0;
  padding: 0;
  width: 100%;
}
</style>
