• Performing a fuzzy search may retrieve terms with similar spellings: (( te sach tai nghiem van hoa ((dam lich) OR (du lich)) ) or ( vu sach thieu tai van hoa su tich ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( te sach tai nghiem van hoa ((dam lich) OR (du lich)) ) OR ( vu sach thieu tai van hoa su tich )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( te sach tai nghiem van hoa ((dam lich) OR (du lich)) ) or ( vu sach thieu tai van hoa su tich ))".
• Adding a wildcard symbol may retrieve word variants: (( te sach tai nghiem van hoa ((dam lich) OR (du lich)) ) or ( vu sach thieu tai van hoa su tich ))*.
