• Performing a fuzzy search may retrieve terms with similar spellings: su sach ty hang ma hoa. hieu ((va cham) or (va tham)) luc gia thanh vi ((cua triet) OR (va triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty hang ma hoa. hieu ((va cham) OR (va tham)) luc gia thanh vi ((cua triet) OR (va triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty hang ma hoa. hieu ((va cham) or (va tham)) luc gia thanh vi ((cua triet) OR (va triet))".
• Adding a wildcard symbol may retrieve word variants: su sach ty hang ma hoa. hieu ((va cham) or (va tham)) luc gia thanh vi ((cua triet) OR (va triet))*.
