• If you are trying to use Boolean operators, they must be ALL CAPS: yuan chang ((tuan hua) OR (tan hua)) ren chan hong ((kong shu) OR (kong siu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yuan chang ((tuan hua) or (tan hua)) ren chan hong ((kong shu) OR (kong siu)) ;~".
• Adding a wildcard symbol may retrieve word variants: yuan chang ((tuan hua) or (tan hua)) ren chan hong ((kong shu) OR (kong siu)) ;*.
