• If you are trying to use Boolean operators, they must be ALL CAPS: ((((yan wang) OR (yuan wang))) OR (yang yang)) can a gene how man one (sau OR saur) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((yan wang) OR (yuan wang))) or (yang yang)) can a gene how man one (sau or saur) ;~".
• Adding a wildcard symbol may retrieve word variants: ((((yan wang) OR (yuan wang))) or (yang yang)) can a gene how man one (sau or saur) ;*.
