• If you are trying to use Boolean operators, they must be ALL CAPS: (( phung thi que van. hoi trung hoc moi ) OR ( nhung thoi rua ban. boi duong hoc moin ))~.
• Adding a wildcard symbol may retrieve word variants: (( phung thi que van. hoi trung hoc moi ) or ( nhung thoi rua ban. boi duong hoc moin ))*.
