• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((xiao yang) or (xiaobo wang)) can have zhang ming ((hong ghi) OR (zhong zhi)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((xiao yang) or (xiaobo wang)) can have zhang ming ((hong ghi) OR (zhong zhi)) ;*.
