• If you are trying to use Boolean operators, they must be ALL CAPS: (( ((tu sach) OR (tu cach)) cha me nguoi dao trong tin ) OR ( su sach cha dan giai co huong tin ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((tu sach) OR (tu cach)) cha me nguoi dao trong tin ) or ( su sach cha dan giai co huong tin ))~".
• Adding a wildcard symbol may retrieve word variants: (( ((tu sach) OR (tu cach)) cha me nguoi dao trong tin ) or ( su sach cha dan giai co huong tin ))*.
