code

//disable WordPress foreground search function disable_search( $query, $error = true ) {if (is_search() && ! is_admin()) {$query->is_search = false;$query->query_vars['s'] = false;$query->query['s'] = false;if ( $error = true )//Error page displayed after executing search// $query->is_home = true; //Go to home page $query->is_404 = true;//Go to page 404}}add_action ( 'parse_query', 'disable_search' );add_filter( 'get_search_form', create_function( '$a', "return null;" ) );
