• If you are trying to use Boolean operators, they must be ALL CAPS: (( nhung thong quan luan. nuoi trong hoc moni ) OR ( phung thi quy van. con dong hoc mon ))~.
• Adding a wildcard symbol may retrieve word variants: (( nhung thong quan luan. nuoi trong hoc moni ) or ( phung thi quy van. con dong hoc mon ))*.
