• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong hoang) OR (dong sin)) ya hua ren ((yan tin) OR (yang lin)) hong shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong hoang) or (dong sin)) ya hua ren ((yan tin) OR (yang lin)) hong shu ;~".
• Adding a wildcard symbol may retrieve word variants: ((dong hoang) or (dong sin)) ya hua ren ((yan tin) OR (yang lin)) hong shu ;*.
