• The words AND, OR and NOT may confuse the search; try adding quotes: "deng zhang zhang i ((cheng zhang) or (zhen zhang)) ((kai cong) OR (bai chong)) shu ;~".
• Adding a wildcard symbol may retrieve word variants: deng zhang zhang i ((cheng zhang) or (zhen zhang)) ((kai cong) OR (bai chong)) shu ;*.
