• If you are trying to use Boolean operators, they must be ALL CAPS: (( phung thi quy van. noi dung phuoc mo ) OR ( trung thanh qui van. con luong nguon mo ))~.
• Adding a wildcard symbol may retrieve word variants: (( phung thi quy van. noi dung phuoc mo ) or ( trung thanh qui van. con luong nguon mo ))*.
