• If you are trying to use Boolean operators, they must be ALL CAPS: wang yan ((((yang jui) OR (yang xi))) OR (((yuan li) OR (yuan zi)))) zhen zhang sing kong shu ;~.
• Adding a wildcard symbol may retrieve word variants: wang yan ((((yang jui) or (yang xi))) or (((yuan li) or (yuan zi)))) zhen zhang sing kong shu ;*.
