• If you are trying to use Boolean operators, they must be ALL CAPS: (( nhung gi quen vang. nuoi duong hoc mo ) OR ( nhung gia tran van. nuoi duong hoi mo ))~.
• Adding a wildcard symbol may retrieve word variants: (( nhung gi quen vang. nuoi duong hoc mo ) or ( nhung gia tran van. nuoi duong hoi mo ))*.
