• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty nang ((me hoi) OR (xa hoi)). hieu van cac vuc van hang tai ((cuc tre) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty nang ((me hoi) or (xa hoi)). hieu van cac vuc van hang tai ((cuc tre) OR (cuu tre))*".
