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