• If you are trying to use Boolean operators, they must be ALL CAPS: (( phung thi que van. noi trung hoc mon ) OR ( nhung toi quyet van. hai duong hoi noi ))~.
• Adding a wildcard symbol may retrieve word variants: (( phung thi que van. noi trung hoc mon ) or ( nhung toi quyet van. hai duong hoi noi ))*.
