• If you are trying to use Boolean operators, they must be ALL CAPS: (( nhung gi quen hanh. hoc dung hoc mo ) OR ( nhung boa quan van. nuoi duong hoi mo ))~.
• Adding a wildcard symbol may retrieve word variants: (( nhung gi quen hanh. hoc dung hoc mo ) or ( nhung boa quan van. nuoi duong hoi mo ))*.
