• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yang) OR (wang ryan)) ((a six) OR (2 six)) west wang ((chi hoang) OR (thi hong)) sy ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yang) or (wang ryan)) ((a six) or (2 six)) west wang ((chi hoang) OR (thi hong)) sy ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yang) or (wang ryan)) ((a six) or (2 six)) west wang ((chi hoang) OR (thi hong)) sy ;*.
