• If you are trying to use Boolean operators, they must be ALL CAPS: (( chung thi que lang. boi duong nguoi moi ) OR ( nhung chu luan hoan. hai luong ngoc mo ))~.
• Adding a wildcard symbol may retrieve word variants: (( chung thi que lang. boi duong nguoi moi ) or ( nhung chu luan hoan. hai luong ngoc mo ))*.
