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