• If you are trying to use Boolean operators, they must be ALL CAPS: ((doi chieu) OR (doi chi)) sang - ((canh tranh) OR (thanh trung)) cua vat cong san than cap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doi chieu) OR (doi chi)) sang - ((canh tranh) or (thanh trung)) cua vat cong san than cap*".
