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