• If you are trying to use Boolean operators, they must be ALL CAPS: ((zhang yan) OR (dong sign)) ye a west ((yang lin) OR (((yuan ting) OR (yuan ming)))) gong hui ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((zhang yan) or (dong sign)) ye a west ((yang lin) or (((yuan ting) OR (yuan ming)))) gong hui ;~".
• Adding a wildcard symbol may retrieve word variants: ((zhang yan) or (dong sign)) ye a west ((yang lin) or (((yuan ting) OR (yuan ming)))) gong hui ;*.
