In addition to the categories of the course fields, you can tell a list to display “other fields”.
The individual elements in the list are not configurable, e.g. you can hide some of the elements.
I'm not sure whether the “additional fields” should be displayed as buttons at all? - Elements such as “Course URL” should then be linked to the input field.
In my quick test, the input and button of the “other fields” were not connected so that the search generated a customized result.
