• If you are trying to use Boolean operators, they must be ALL CAPS: (( chung cho quen hanh. cho tu truc va ) OR ( nhung thoi que van. hoi truyen tu lap ))~.
• Adding a wildcard symbol may retrieve word variants: (( chung cho quen hanh. cho tu truc va ) or ( nhung thoi que van. hoi truyen tu lap ))*.
