I used what I read there and after doing some searches found that I should change the category to search. My Custom CSS now has this in it, but the sidebar still shows on the search page. Do I have to do something special when adding more than one thing to the Custom CSS?
add_filter( 'generate_sidebar_layout','generate_custom_category_sidebar_layout' );
function generate_custom_category_sidebar_layout( $layout )
// If we are on a category, set the sidebar
if ( is_search() )
// Or else, set the regular layout
