• Performing a fuzzy search may retrieve terms with similar spellings: te sach ty sang ma hoa. hieu ve cao duc va ((danh lai) or (tinh lao)) ((cua tu) OR (cua su))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty sang ma hoa. hieu ve cao duc va ((danh lai) OR (tinh lao)) ((cua tu) OR (cua su)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty sang ma hoa. hieu ve cao duc va ((danh lai) or (tinh lao)) ((cua tu) OR (cua su))".
• Adding a wildcard symbol may retrieve word variants: te sach ty sang ma hoa. hieu ve cao duc va ((danh lai) or (tinh lao)) ((cua tu) OR (cua su))*.
