• Performing a fuzzy search may retrieve terms with similar spellings: te sach ty sang ((ma hoi) or (xa hoi)). thien van cam duc van dinh lai ((cuu tre) OR (cau treo))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty sang ((ma hoi) OR (xa hoi)). thien van cam duc van dinh lai ((cuu tre) OR (cau treo))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty sang ((ma hoi) or (xa hoi)). thien van cam duc van dinh lai ((cuu tre) OR (cau treo))*".
