• The words AND, OR and NOT may confuse the search; try adding quotes: "wang xiaodong zhang cheng ((((weng fang) OR (jing fang))) or (wen wang)) jie zhang hari ;~".
• Adding a wildcard symbol may retrieve word variants: wang xiaodong zhang cheng ((((weng fang) OR (jing fang))) or (wen wang)) jie zhang hari ;*.
