• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (theo tieu)) sach - thanh trung tham nhung cong ((dan than) OR (dan chan)) cap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (theo tieu)) sach - thanh trung tham nhung cong ((dan than) OR (dan chan)) cap".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (theo tieu)) sach - thanh trung tham nhung cong ((dan than) OR (dan chan)) cap*.
