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