• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang ning) OR (wang liang)) ((tan zhi) OR (yuan li)) gene bank can leong ghi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang ning) OR (wang liang)) ((tan zhi) or (yuan li)) gene bank can leong ghi ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang ning) OR (wang liang)) ((tan zhi) or (yuan li)) gene bank can leong ghi ;*.
