The code that Dave is giving you goes above just displaying the search term, it will also display a unique label beside aeach search term depending on which form element it is coming from.
In his example code, he has different form elements, one is named "S_publish" another is named "S_details".
his code is displaying a unique label, so if the user searched for details and published, the display would look like:
Description: <detail search term>
Published: <published search term.
if all you want to do is show the search term, go to the bindings panel and click on the plus button.
Select Form Data, click the folder icon and select your search form.
this will add dynamic data bindings for the search form on the results page.
In the bindings panel expand the search form, then drag the form element binding to the results page where you want it displayed, repeat for any other form elements you wish to display.
