• If you are trying to use Boolean operators, they must be ALL CAPS: (( chung thong quyet van. noi dung hoc mot ) OR ( phung thi quen van. nguoi mong doi mo ))~.
• Adding a wildcard symbol may retrieve word variants: (( chung thong quyet van. noi dung hoc mot ) or ( phung thi quen van. nguoi mong doi mo ))*.
