• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc chieu) OR (ho chieu)) sach - hanh trinh quan chong cong ((van toan) OR (van tan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc chieu) or (ho chieu)) sach - hanh trinh quan chong cong ((van toan) OR (van tan)) cau~".
• Adding a wildcard symbol may retrieve word variants: ((hoc chieu) or (ho chieu)) sach - hanh trinh quan chong cong ((van toan) OR (van tan)) cau*.
