• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - thanh truong ((quan nhung) OR (luan chung)) cong ((ban than) OR (ban thanh)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - thanh truong ((quan nhung) OR (luan chung)) cong ((ban than) or (ban thanh)) cau~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - thanh truong ((quan nhung) OR (luan chung)) cong ((ban than) or (ban thanh)) cau*.
