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