• Performing a fuzzy search may retrieve terms with similar spellings: su sach ky lang xa hoi. hieu ve cao duc va tinh ((lam cua) or (((hai cua) OR (thai cua)))) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky lang xa hoi. hieu ve cao duc va tinh ((lam cua) OR (((hai cua) OR (thai cua)))) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky lang xa hoi. hieu ve cao duc va tinh ((lam cua) or (((hai cua) OR (thai cua)))) triet".
• Adding a wildcard symbol may retrieve word variants: su sach ky lang xa hoi. hieu ve cao duc va tinh ((lam cua) or (((hai cua) OR (thai cua)))) triet*.
