• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong bin) OR (dong hoang)) ((yaa china) OR (a china)) won wang ban ((yang yi) OR (yang di)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong bin) or (dong hoang)) ((yaa china) OR (a china)) won wang ban ((yang yi) or (yang di)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((dong bin) or (dong hoang)) ((yaa china) OR (a china)) won wang ban ((yang yi) or (yang di)) ;*.
