• Performing a fuzzy search may retrieve terms with similar spellings: thu ((sach ty) OR (sach thu)) tang van hoi. hieu ((qua cai) or (qua ca)) duc va hanh den su triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach ty) OR (sach thu)) tang van hoi. hieu ((qua cai) OR (qua ca)) duc va hanh den su triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach ty) OR (sach thu)) tang van hoi. hieu ((qua cai) or (qua ca)) duc va hanh den su triet".
