• The words AND, OR and NOT may confuse the search; try adding quotes: "wang zhang tan hua gene ((((((yang jun) OR (yang judy))) or (yang jui))) or (yang yi)) wong sau ;~".
• Adding a wildcard symbol may retrieve word variants: wang zhang tan hua gene ((((((yang jun) OR (yang judy))) or (yang jui))) or (yang yi)) wong sau ;*.
