• If you are trying to use Boolean operators, they must be ALL CAPS: ((yang yi) OR (yang yang)) das human bad ((bank die) OR (bank deep)) zhang ghi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang yi) or (yang yang)) das human bad ((bank die) OR (bank deep)) zhang ghi ;~".
• Adding a wildcard symbol may retrieve word variants: ((yang yi) or (yang yang)) das human bad ((bank die) OR (bank deep)) zhang ghi ;*.
