• If you are trying to use Boolean operators, they must be ALL CAPS: (( nhung tri quen vang. nuoi duong hoc mo ) OR ( nhung thai quang va. bi cong hoc mon ))~.
• Adding a wildcard symbol may retrieve word variants: (( nhung tri quen vang. nuoi duong hoc mo ) or ( nhung thai quang va. bi cong hoc mon ))*.
