• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yang) OR (yang jin)) zhang jing fang yang ((die menge) OR (die mangel)) (star OR start) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yang) or (yang jin)) zhang jing fang yang ((die menge) OR (die mangel)) (star or start) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yang) or (yang jin)) zhang jing fang yang ((die menge) OR (die mangel)) (star or start) ;*.
