• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (thi chieu)) tinh - canh tranh cua nhung cong ((hach toan) OR (thanh toan)) tap~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (thi chieu)) tinh - canh tranh cua nhung cong ((hach toan) OR (thanh toan)) tap*.
