• If you are trying to use Boolean operators, they must be ALL CAPS: ((yuan kang) OR (((yuan wang) OR (yan wang)))) liang a gene w than wong shiu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yuan kang) or (((yuan wang) OR (yan wang)))) liang a gene w than wong shiu ;~".
• Adding a wildcard symbol may retrieve word variants: ((yuan kang) or (((yuan wang) OR (yan wang)))) liang a gene w than wong shiu ;*.
