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