• If you are trying to use Boolean operators, they must be ALL CAPS: (( phung thi quen vang. hoc dung hoc mo ) OR ( nhung thi que van. nguoi tuong hoc mo ))~.
• Adding a wildcard symbol may retrieve word variants: (( phung thi quen vang. hoc dung hoc mo ) or ( nhung thi que van. nguoi tuong hoc mo ))*.
