• If you are trying to use Boolean operators, they must be ALL CAPS: (( chung cho que lang. nuoi duong hoc mot ) OR ( nhung thi quen van. boi duong hoi noi ))~.
• Adding a wildcard symbol may retrieve word variants: (( chung cho que lang. nuoi duong hoc mot ) or ( nhung thi quen van. boi duong hoi noi ))*.
