• Performing a fuzzy search may retrieve terms with similar spellings: ho chieu sach - ((cthanh van) or (thanh van)) cua dong huong ((dan toan) OR (van toan)) cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - ((cthanh van) OR (thanh van)) cua dong huong ((dan toan) OR (van toan)) cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - ((cthanh van) or (thanh van)) cua dong huong ((dan toan) OR (van toan)) cau".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - ((cthanh van) or (thanh van)) cua dong huong ((dan toan) OR (van toan)) cau*.
