How to redirect a request to a controller in Yii using a non-standard url?

Question

Yii

In the action of the form I use the following url: docs/index.php?r=search/index, how to redirect the user to the pages: http://docs/index.php?r=search/index&query=query text ?
When a request is sent, it goes to docs/index.php?query=wawa

Answer 1

/**
 * Экшен осуществляющий редирект
 *
 * @return \yii\web\Response
 */
public function actionExampe()
{
    return $this->redirect(['search/index', 'query' => 'wawa']);
}
