• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yang yao) OR (yang fan)) ((yuan kong) OR (tan kong)) young jui kang han ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yang yao) or (yang fan)) ((yuan kong) OR (tan kong)) young jui kang han ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yang yao) or (yang fan)) ((yuan kong) OR (tan kong)) young jui kang han ;*.
