* @return mixed
*/
public function actionIndex($mode=null)
{
$searchModel = new DocumentSearch();
if(!$mode) {
$this->loadParams();
$mode = Yii::$app->request->get('mode');
}
$this->saveParams('DocumentSearch',['mode'=>1]);
$dataProvider = $searchModel->search(Yii::$app->request->queryParams);
return $this->render('index', [
