• Performing a fuzzy search may retrieve terms with similar spellings: te sach v nang ((mai hoi) OR (dai hoi)). hieu ve cac ((vuc van) or (luc van)) quang dien cua tuc~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach v nang ((mai hoi) OR (dai hoi)). hieu ve cac ((vuc van) OR (luc van)) quang dien cua tuc.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach v nang ((mai hoi) OR (dai hoi)). hieu ve cac ((vuc van) or (luc van)) quang dien cua tuc".
• Adding a wildcard symbol may retrieve word variants: te sach v nang ((mai hoi) OR (dai hoi)). hieu ve cac ((vuc van) or (luc van)) quang dien cua tuc*.
