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