• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach che my gioi ((co thong) OR (co trong)) minh ) OR ( tu sach ca va gioi co hong minh ))~.
• Adding a wildcard symbol may retrieve word variants: (( tu sach che my gioi ((co thong) or (co trong)) minh ) or ( tu sach ca va gioi co hong minh ))*.
