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