• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (thu sach)) y nang xa hoi. sieu viet cac co van anh vai ((cuu tre) OR (cau treo))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (thu sach)) y nang xa hoi. sieu viet cac co van anh vai ((cuu tre) or (cau treo))*".
