• The words AND, OR and NOT may confuse the search; try adding quotes: "wang jia yi hua (rene or gene) yuan ((((hong hong) OR (hong ng))) or (hong jong)) tan ;~".
• Adding a wildcard symbol may retrieve word variants: wang jia yi hua (rene or gene) yuan ((((hong hong) OR (hong ng))) or (hong jong)) tan ;*.
