• If you are trying to use Boolean operators, they must be ALL CAPS: (((( tu sach hoi tap nguoi ) OR ( tu manh ho lap nguoi ))) OR ( thuoc sach hoc dan nguoi ))~.
• Adding a wildcard symbol may retrieve word variants: (((( tu sach hoi tap nguoi ) or ( tu manh ho lap nguoi ))) or ( thuoc sach hoc dan nguoi ))*.
