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