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