• If you are trying to use Boolean operators, they must be ALL CAPS: so anh y tang ma hoi. hieu ((((ve cham) OR (vu cham))) OR (ve cac)) tuc van hanh lai cua viet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so anh y tang ma hoi. hieu ((((ve cham) OR (vu cham))) or (ve cac)) tuc van hanh lai cua viet*".
