• If you are trying to use Boolean operators, they must be ALL CAPS: wang fan ying jin ((((yi kang) OR (jin kang))) OR (xi kang)) minh ((cong du) OR (cong shu)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang fan ying jin ((((yi kang) OR (jin kang))) or (xi kang)) minh ((cong du) or (cong shu)) ;*".
