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