• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky nang ((ma hoi) OR (ma hoa)). hieu ve cam xuc va hanh ((vi cua) OR (vai cua)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky nang ((ma hoi) OR (ma hoa)). hieu ve cam xuc va hanh ((vi cua) or (vai cua)) triet".
• Adding a wildcard symbol may retrieve word variants: su sac ky nang ((ma hoi) OR (ma hoa)). hieu ve cam xuc va hanh ((vi cua) or (vai cua)) triet*.
