• If you are trying to use Boolean operators, they must be ALL CAPS: wang yan tao hua ren ((yuan kang) OR (yang lin)) ((hong ghi) OR (((hong hai) OR (zhong tai)))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan tao hua ren ((yuan kang) or (yang lin)) ((hong ghi) or (((hong hai) OR (zhong tai)))) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan tao hua ren ((yuan kang) or (yang lin)) ((hong ghi) or (((hong hai) OR (zhong tai)))) ;*.
