• Performing a fuzzy search may retrieve terms with similar spellings: su sach ky sang ((ma hoi) OR (xa hoi)). hieu ve cham xuc ((va hanh) or (va dinh)) hai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky sang ((ma hoi) OR (xa hoi)). hieu ve cham xuc ((va hanh) OR (va dinh)) hai cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky sang ((ma hoi) OR (xa hoi)). hieu ve cham xuc ((va hanh) or (va dinh)) hai cua triet*".
