• Performing a fuzzy search may retrieve terms with similar spellings: vu cac ky lang van hoa. hieu ve cac loc va ((tinh ca) OR (tinh cao)) ((cua tre) or (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu cac ky lang van hoa. hieu ve cac loc va ((tinh ca) OR (tinh cao)) ((cua tre) OR (cua te))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu cac ky lang van hoa. hieu ve cac loc va ((tinh ca) OR (tinh cao)) ((cua tre) or (cua te))*".
