• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong hoang) or (wang yang)) ka yuan wei qiang ((jing fang) OR (jia fang)) (hai or hari) ;~".
• Adding a wildcard symbol may retrieve word variants: ((dong hoang) or (wang yang)) ka yuan wei qiang ((jing fang) OR (jia fang)) (hai or hari) ;*.
