• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang yi hua gene tang min ((hong shu) or (((((tong shui) OR (cong shu))) or (gong hui)))) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang yi hua gene tang min ((hong shu) or (((((tong shui) OR (cong shu))) or (gong hui)))) ;*.
