• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang danning) OR (wang daoping)) ya hua ((gene bank) OR (die bank)) amin hong tai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang danning) OR (wang daoping)) ya hua ((gene bank) or (die bank)) amin hong tai ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang danning) OR (wang daoping)) ya hua ((gene bank) or (die bank)) amin hong tai ;*.
