• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chieu) OR (ho chieu)) sang - ((hanh dung) OR (thanh dung)) cua trung phuong doan toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chieu) OR (ho chieu)) sang - ((hanh dung) or (thanh dung)) cua trung phuong doan toan cau~".
• Adding a wildcard symbol may retrieve word variants: ((theo chieu) OR (ho chieu)) sang - ((hanh dung) or (thanh dung)) cua trung phuong doan toan cau*.
