• If you are trying to use Boolean operators, they must be ALL CAPS: (( ((so sach) OR (co sach)) thue me gioi co phong tinh ) OR ( so cach pha ve gioi he hoang minh ))~.
• Adding a wildcard symbol may retrieve word variants: (( ((so sach) or (co sach)) thue me gioi co phong tinh ) or ( so cach pha ve gioi he hoang minh ))*.
