$query->matching(

        $query->equals('user_to', $userUid)
    )
);

return $query->execute();

this code does't work properly. Help me please anybody

Answer 1

    $query = $this->createQuery();
    $constraints = array();

    $constraints[] = $query->logicalNot($query->equals('deleted_by_user', $userUid));
    $constraints[] = $query->logicalOr($query->equals('user_from', $userUid), $query->equals('user_to', $userUid));
    $query->matching($query->logicalAnd($constraints));

    return $query->execute();
