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