• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan ((((yang jun) or (yang jin))) or (yang jui)) gene bank ((aid young) OR (a young)) ghi ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan ((((yang jun) or (yang jin))) or (yang jui)) gene bank ((aid young) OR (a young)) ghi ;*.
