• If you are trying to use Boolean operators, they must be ALL CAPS: ho hieu lang - thanh duong ((thanh dung) OR (hanh dung)) cong tan ((thanh cham) OR (thanh cha))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho hieu lang - thanh duong ((thanh dung) OR (hanh dung)) cong tan ((thanh cham) or (thanh cha))*".
