• If you are trying to use Boolean operators, they must be ALL CAPS: (( nhung thoi que van. thi truong hoc mon ) OR ( phung thi quan van. nuoi duong hoc mo ))~.
• Adding a wildcard symbol may retrieve word variants: (( nhung thoi que van. thi truong hoc mon ) or ( phung thi quan van. nuoi duong hoc mo ))*.
