• If you are trying to use Boolean operators, they must be ALL CAPS: (( nhung tri quan vi. noi dung hoc moi ) OR ( nhung chi hue van. dai cuong hoc mot ))~.
• Adding a wildcard symbol may retrieve word variants: (( nhung tri quan vi. noi dung hoc moi ) or ( nhung chi hue van. dai cuong hoc mot ))*.
