• If you are trying to use Boolean operators, they must be ALL CAPS: ((su xac) OR (su cac)) ky nang x hoi. hieu ve gap nguoi ((san hanh) OR (san thanh)) de cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su xac) OR (su cac)) ky nang x hoi. hieu ve gap nguoi ((san hanh) or (san thanh)) de cua triet".
• Adding a wildcard symbol may retrieve word variants: ((su xac) OR (su cac)) ky nang x hoi. hieu ve gap nguoi ((san hanh) or (san thanh)) de cua triet*.
