• If you are trying to use Boolean operators, they must be ALL CAPS: wang liu yang ((jui chen) OR (yu chen)) chan tang ((chun h) OR (chung h)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang liu yang ((jui chen) or (yu chen)) chan tang ((chun h) OR (chung h)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang liu yang ((jui chen) or (yu chen)) chan tang ((chun h) OR (chung h)) ;*.
