• If you are trying to use Boolean operators, they must be ALL CAPS: (( phuong trong quan van. con duong phuoc mo ) OR ( nhung tri que lang. con duong hoc mo ))~.
• Adding a wildcard symbol may retrieve word variants: (( phuong trong quan van. con duong phuoc mo ) or ( nhung tri que lang. con duong hoc mo ))*.
