• If you are trying to use Boolean operators, they must be ALL CAPS: ((yuan wang) OR (yuan kang)) tan hua ren yan mun ((kyoung yun) OR (hyoung gun)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yuan wang) or (yuan kang)) tan hua ren yan mun ((kyoung yun) OR (hyoung gun)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((yuan wang) or (yuan kang)) tan hua ren yan mun ((kyoung yun) OR (hyoung gun)) ;*.
