• Performing a fuzzy search may retrieve terms with similar spellings: te sac ky ((lang xa) or (((lang van) OR (tang van)))) hoi. hieu van lam duc va doanh van cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky ((lang xa) OR (((lang van) OR (tang van)))) hoi. hieu van lam duc va doanh van cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky ((lang xa) or (((lang van) OR (tang van)))) hoi. hieu van lam duc va doanh van cuu tre".
• Adding a wildcard symbol may retrieve word variants: te sac ky ((lang xa) or (((lang van) OR (tang van)))) hoi. hieu van lam duc va doanh van cuu tre*.
