• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((qiao wang) OR (xiao yang)) li lu sang minh ((hong shu) OR (wang hui)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((qiao wang) OR (xiao yang)) li lu sang minh ((hong shu) or (wang hui)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((qiao wang) OR (xiao yang)) li lu sang minh ((hong shu) or (wang hui)) ;*.
