• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong tin) OR (dong sin)) tan china's road loading ((jin song) or (john song)) shin ;~".
• Adding a wildcard symbol may retrieve word variants: ((dong tin) OR (dong sin)) tan china's road loading ((jin song) or (john song)) shin ;*.
