• If you are trying to use Boolean operators, they must be ALL CAPS: fang ((zhen yan) OR (zhang yan)) ((yi chin) OR (yi chen)) chang wang hong yu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "fang ((zhen yan) OR (zhang yan)) ((yi chin) or (yi chen)) chang wang hong yu ;~".
• Adding a wildcard symbol may retrieve word variants: fang ((zhen yan) OR (zhang yan)) ((yi chin) or (yi chen)) chang wang hong yu ;*.
