• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang ((x hoi) OR (x ho)). hieu van bac thuc ban ((thanh van) OR (thanh hai)) va triet.
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang ((x hoi) or (x ho)). hieu van bac thuc ban ((thanh van) or (thanh hai)) va triet*.
