• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yang yi) OR (yang xi)) hui ren ((gan li) OR (huang jing)) shang kai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yang yi) OR (yang xi)) hui ren ((gan li) or (huang jing)) shang kai ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yang yi) OR (yang xi)) hui ren ((gan li) or (huang jing)) shang kai ;*.
