Check If search query contains something?
After the question’s update, I think that you need to set the canonical URL: add_action( ‘wp_head’, ‘cyb_search_results_canonical_URL’ ); function cyb_search_results_canonical_URL() { if( is_search() ) { $link = get_search_link(); echo ‘<link rel=”canonical” href=”‘ . esc_url( $link ) . ‘”>’; } } And your problem with duplicated content is fixed.
