• If you are trying to use Boolean operators, they must be ALL CAPS: ((so sanh) OR (co sach)) ty nang x hoi. hieu ve cai nuoc va ((danh di) OR (danh du)) cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((so sanh) or (co sach)) ty nang x hoi. hieu ve cai nuoc va ((danh di) OR (danh du)) cua te*".
