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