• If you are trying to use Boolean operators, they must be ALL CAPS: lang yan ((((ying hua) OR (yang hui))) OR (yang jui)) jin ((pang yan) OR (zhang yan)) congo shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yan ((((ying hua) or (yang hui))) or (yang jui)) jin ((pang yan) OR (zhang yan)) congo shu ;~".
• Adding a wildcard symbol may retrieve word variants: lang yan ((((ying hua) or (yang hui))) or (yang jui)) jin ((pang yan) OR (zhang yan)) congo shu ;*.
