• If you are trying to use Boolean operators, they must be ALL CAPS: (( nhung thoi rua van. doi tuong ngoai mo ) OR ( nhung bi que van. noi dung hoc mo ))~.
• Adding a wildcard symbol may retrieve word variants: (( nhung thoi rua van. doi tuong ngoai mo ) or ( nhung bi que van. noi dung hoc mo ))*.
