• Performing a fuzzy search may retrieve terms with similar spellings: hoc thieu sach - thanh ((((hoang hoa) OR (hoang thoan))) or (hoang ha)) nhung cong nam van ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu sach - thanh ((((hoang hoa) OR (hoang thoan))) OR (hoang ha)) nhung cong nam van ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu sach - thanh ((((hoang hoa) OR (hoang thoan))) or (hoang ha)) nhung cong nam van ban".
• Adding a wildcard symbol may retrieve word variants: hoc thieu sach - thanh ((((hoang hoa) OR (hoang thoan))) or (hoang ha)) nhung cong nam van ban*.
