How to exclude one post format from search result?
You could probably do it my modifying the loop through the pre_get_posts hook. function wpse163459_search_exclude_post_format( $query ) { if( $query->is_main_query() && $query->is_search() ) { $tax_query = array( array( ‘taxonomy’ => ‘post_format’, ‘field’ => ‘slug’, ‘terms’ => array( ‘post-format-quote’ ), ‘operator’ => ‘NOT IN’, ) ); $query->set( ‘tax_query’, $tax_query ); } } add_action( ‘pre_get_posts’, ‘wpse163459_search_exclude_post_format’ );
