• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang nan) OR (wang dan)) ((yan zi) OR (yan zhi)) (zhen OR zheng) zhang xin song sein ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang nan) or (wang dan)) ((yan zi) OR (yan zhi)) (zhen or zheng) zhang xin song sein ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang nan) or (wang dan)) ((yan zi) OR (yan zhi)) (zhen or zheng) zhang xin song sein ;*.
