• Performing a fuzzy search may retrieve terms with similar spellings: ((te cac) OR (te cao)) ky lang xa hoi. thien van pham duc ban thanh hoi ((cua tre) or (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((te cac) OR (te cao)) ky lang xa hoi. thien van pham duc ban thanh hoi ((cua tre) OR (cua te))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te cac) OR (te cao)) ky lang xa hoi. thien van pham duc ban thanh hoi ((cua tre) or (cua te))*".
