• If you are trying to use Boolean operators, they must be ALL CAPS: (( nhung ban quan vi. nguoi tuong hoc mon ) OR ( dung mai quan vang. nuoi duong hoc mo ))~.
• Adding a wildcard symbol may retrieve word variants: (( nhung ban quan vi. nguoi tuong hoc mon ) or ( dung mai quan vang. nuoi duong hoc mo ))*.
