• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) ky nang xa hoi. thien van cay qua ((ban hang) OR (ngan hang)) tai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (te sach)) ky nang xa hoi. thien van cay qua ((ban hang) OR (ngan hang)) tai cua te".
