• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hieu manh - manh dung cua nhung cong dan ((than cau) or (((than cap) OR (thanh lap))))~".
• Adding a wildcard symbol may retrieve word variants: hoc hieu manh - manh dung cua nhung cong dan ((than cau) or (((than cap) OR (thanh lap))))*.
