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