• Performing a fuzzy search may retrieve terms with similar spellings: tu sach de ((lang xa) or (((lang van) OR (tang van)))) hoi. hieu va bao tuc va danh sai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach de ((lang xa) OR (((lang van) OR (tang van)))) hoi. hieu va bao tuc va danh sai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach de ((lang xa) or (((lang van) OR (tang van)))) hoi. hieu va bao tuc va danh sai cua te".
• Adding a wildcard symbol may retrieve word variants: tu sach de ((lang xa) or (((lang van) OR (tang van)))) hoi. hieu va bao tuc va danh sai cua te*.
