• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (theo chu)) sach - thanh trung cua ((nhung cong) OR (hang cong)) san ca cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (theo chu)) sach - thanh trung cua ((nhung cong) OR (hang cong)) san ca cau*".
