I can’t find a way to set the template for the page that displays returned search results. It always uses the one side bar template and since I have no widgets defined in the side bar it just shows whitespace which is wasted (anda warning in the Dashboard preview).
To solve this I hoped to be able to set “Default Template” to be without sidebars or to define a template to associate with the search results. If this can’t be done from the WP Dashboard then I’m happy to create / edit php template files but I’d like to understand the correct way to do this in the theme.
