• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((liang wang) OR (liang tan)) hua zhong zhang minh ((hong hai) or (zhong zhi)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((liang wang) OR (liang tan)) hua zhong zhang minh ((hong hai) or (zhong zhi)) ;*.
