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