• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach ba ve gia cong thuong minh ) OR ( su sach ((xa me) OR (ca me)) giai con khoang minh ))~.
• Adding a wildcard symbol may retrieve word variants: (( tu sach ba ve gia cong thuong minh ) or ( su sach ((xa me) or (ca me)) giai con khoang minh ))*.
