• If you are trying to use Boolean operators, they must be ALL CAPS: ((mot chieu) OR (ho chieu)) sach - canh tranh cua dung cong ((bang than) OR (bang thanh)) ma*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((mot chieu) or (ho chieu)) sach - canh tranh cua dung cong ((bang than) OR (bang thanh)) ma*".
