• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((xiaoping shi) OR (xiaoping how)) china wen yang jui ((zhang hai) OR (zhang han)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((xiaoping shi) or (xiaoping how)) china wen yang jui ((zhang hai) OR (zhang han)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((xiaoping shi) or (xiaoping how)) china wen yang jui ((zhang hai) OR (zhang han)) ;*.
