• If you are trying to use Boolean operators, they must be ALL CAPS: so sac ky nang ho hoi. ((((hieu ve) OR (hieu va))) OR (hieu van)) cac thu van hanh dieu cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sac ky nang ho hoi. ((((hieu ve) OR (hieu va))) or (hieu van)) cac thu van hanh dieu cua triet*".
