• If you are trying to use Boolean operators, they must be ALL CAPS: ((mot chieu) OR (doi chieu)) sach - hanh trong qua bang cong ((dan toan) OR (dan than)) cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((mot chieu) or (doi chieu)) sach - hanh trong qua bang cong ((dan toan) OR (dan than)) cau".
• Adding a wildcard symbol may retrieve word variants: ((mot chieu) or (doi chieu)) sach - hanh trong qua bang cong ((dan toan) OR (dan than)) cau*.
