• If you are trying to use Boolean operators, they must be ALL CAPS: ((hong yang) OR (hong gang)) yang ((di chen) OR (yi chen)) zhang amin hong 情 ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hong yang) or (hong gang)) yang ((di chen) OR (yi chen)) zhang amin hong 情 ;~".
• Adding a wildcard symbol may retrieve word variants: ((hong yang) or (hong gang)) yang ((di chen) OR (yi chen)) zhang amin hong 情 ;*.
