• If you are trying to use Boolean operators, they must be ALL CAPS: (( chung thi que van. boi duong hoc mot ) OR ( nhung thoi quy van. nuoi trong ngoc mo ))~.
• Adding a wildcard symbol may retrieve word variants: (( chung thi que van. boi duong hoc mot ) or ( nhung thoi quy van. nuoi trong ngoc mo ))*.
