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