• If you are trying to use Boolean operators, they must be ALL CAPS: wang xiao jian ((change chen) OR (change when)) chuan eng ((hong ghi) OR (zhong zhi)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang xiao jian ((change chen) OR (change when)) chuan eng ((hong ghi) or (zhong zhi)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang xiao jian ((change chen) OR (change when)) chuan eng ((hong ghi) or (zhong zhi)) ;*.
