• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yang yuan) OR (yang yun)) hua ((((jie zhang) OR (xi zhang))) OR (bin zhang)) i song jin ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yang yuan) OR (yang yun)) hua ((((jie zhang) or (xi zhang))) or (bin zhang)) i song jin ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yang yuan) OR (yang yun)) hua ((((jie zhang) or (xi zhang))) or (bin zhang)) i song jin ;*.
