• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky nang cao hoi. thien van nam ((((loc van) OR (loc va))) OR (duc van)) thanh vi cua triet.
• Adding a wildcard symbol may retrieve word variants: te sac ky nang cao hoi. thien van nam ((((loc van) or (loc va))) or (duc van)) thanh vi cua triet*.
