• The words AND, OR and NOT may confuse the search; try adding quotes: "((pioneer days) OR (pioneer years)) tan chia dan ((yang jie) or (yang jin)) tong shui ;~".
• Adding a wildcard symbol may retrieve word variants: ((pioneer days) OR (pioneer years)) tan chia dan ((yang jie) or (yang jin)) tong shui ;*.
