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