• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky nang ((ma hoi) OR (mai hoi)). hieu ve cam ((xuc va) OR (luc va)) thanh doi cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky nang ((ma hoi) or (mai hoi)). hieu ve cam ((xuc va) OR (luc va)) thanh doi cua triet".
