• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chieu) OR (chao chu)) xanh - hanh ban cua nhung cong ((tac toan) OR (hach toan)) cao~".
• Adding a wildcard symbol may retrieve word variants: ((theo chieu) OR (chao chu)) xanh - hanh ban cua nhung cong ((tac toan) OR (hach toan)) cao*.
