• If you are trying to use Boolean operators, they must be ALL CAPS: ((yuan kai) OR (yuan chang)) ((yang i) OR (yang xi)) gene clone thanh van paul ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yuan kai) or (yuan chang)) ((yang i) OR (yang xi)) gene clone thanh van paul ;~".
• Adding a wildcard symbol may retrieve word variants: ((yuan kai) or (yuan chang)) ((yang i) OR (yang xi)) gene clone thanh van paul ;*.
