• If you are trying to use Boolean operators, they must be ALL CAPS: (( chung nghi qua van. boi duong hoc mon ) OR ( nhung thoi quy van. nguoi muong ngoai mo ))~.
• Adding a wildcard symbol may retrieve word variants: (( chung nghi qua van. boi duong hoc mon ) or ( nhung thoi quy van. nguoi muong ngoai mo ))*.
