• If you are trying to use Boolean operators, they must be ALL CAPS: ((long han) OR (long chain)) ((van hua) OR (van ha)) gene yan ((jiu hong) OR (tin hong)) shu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((long han) OR (long chain)) ((van hua) or (van ha)) gene yan ((jiu hong) or (tin hong)) shu ;*".
