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