• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (vu khach)) ky sang ma hoi. hieu ly ((na thu) OR (va thu)) va hanh di ca viet~.
• Adding a wildcard symbol may retrieve word variants: ((su sach) or (vu khach)) ky sang ma hoi. hieu ly ((na thu) or (va thu)) va hanh di ca viet*.
