The "search hierarchy!" link will execute this search:
((342/19 <IN> CPC) <OR> (342/19.1 <IN> CPC) <OR> (342/19.2 <IN> CPC) <OR> (342/19.3 <IN> CPC) <OR> (342/19.4 <IN> CPC) <OR> (342/19.5 <IN> CPC) <OR> (342/19.6 <IN> CPC) <OR> (342/19.7 <IN> CPC) <OR> (342/19.8 <IN> CPC))

This will show what classes derive from the input. Ex: entering 78/35 shows the derived classes and the search that can be used to find patents in those subclasses.
