• If you are trying to use Boolean operators, they must be ALL CAPS: ((((zhang fan) OR (wang yan))) OR (dong jung)) yet ((a wei) OR (ma wei)) wang kim wang hua ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((zhang fan) or (wang yan))) or (dong jung)) yet ((a wei) OR (ma wei)) wang kim wang hua ;~".
• Adding a wildcard symbol may retrieve word variants: ((((zhang fan) or (wang yan))) or (dong jung)) yet ((a wei) OR (ma wei)) wang kim wang hua ;*.
