• If you are trying to use Boolean operators, they must be ALL CAPS: ((wing yan) OR (wing ian)) tuan hua rent ((yan jiu) OR (yang jin)) wong sau ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wing yan) OR (wing ian)) tuan hua rent ((yan jiu) or (yang jin)) wong sau ;~".
• Adding a wildcard symbol may retrieve word variants: ((wing yan) OR (wing ian)) tuan hua rent ((yan jiu) or (yang jin)) wong sau ;*.
