• If you are trying to use Boolean operators, they must be ALL CAPS: ((huang cheng) OR (huang ying)) can ((china state) OR (china's state)) wang hong hoang yu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((huang cheng) or (huang ying)) can ((china state) OR (china's state)) wang hong hoang yu ;~".
• Adding a wildcard symbol may retrieve word variants: ((huang cheng) or (huang ying)) can ((china state) OR (china's state)) wang hong hoang yu ;*.
