My theme seems to be stopping the search box from displaying is that something that is fixable?
This situation is often easily fixed. The Swiftype WordPress search plugin takes over the default WordPress search widget. As a result, you just need to ensure you have the default search widget active in your theme for Swiftype to work. You can enable this by going to the Appearance -> Widgets section of your WordPress admin dashboard, and then drag the "Search" widget into the side bar.
