• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR lang) ((yan yuan) OR (yihan guan)) li chen kian ((ming kong) OR (king kong)) sar ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or lang) ((yan yuan) or (yihan guan)) li chen kian ((ming kong) OR (king kong)) sar ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or lang) ((yan yuan) or (yihan guan)) li chen kian ((ming kong) OR (king kong)) sar ;*.
