• If you are trying to use Boolean operators, they must be ALL CAPS: wang xiao ((han chen) OR (han chang)) chuan chuan ((ong chong) OR (ong cheng)) hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang xiao ((han chen) or (han chang)) chuan chuan ((ong chong) OR (ong cheng)) hai ;~".
• Adding a wildcard symbol may retrieve word variants: wang xiao ((han chen) or (han chang)) chuan chuan ((ong chong) OR (ong cheng)) hai ;*.
