• The words AND, OR and NOT may confuse the search; try adding quotes: "((((yang yi) or (wang yan))) or (yang di))nr ((5 many) OR (5 man)) gene bank 2nd china going ;~".
• Adding a wildcard symbol may retrieve word variants: ((((yang yi) or (wang yan))) or (yang di))nr ((5 many) OR (5 man)) gene bank 2nd china going ;*.
