• If you are trying to use Boolean operators, they must be ALL CAPS: hong sheng li hua ((yang yang) OR (tan yang)) min ((hong zhi) OR (((zhang zhi) OR (zhong tai)))) ;~.
• Adding a wildcard symbol may retrieve word variants: hong sheng li hua ((yang yang) or (tan yang)) min ((hong zhi) or (((zhang zhi) or (zhong tai)))) ;*.
