Finding all instances connected to net and pin names

Hello, I wish to find all instances which connect to a net/pin name. What I've tried so far:

valid_nets=dbFindNetByName(cv pin_name)

valid_terms=dbFindTermByName(cv pin_name)

CurrTerm=nil

if(valid_nets&&valid_terms then

  CurrTerm = append( valid_nets~>instTerms valid_terms~>nets->instTerms )

else

if( valid_terms then

  CurrTerm = valid_terms~>nets->instTerms

) if( valid_nets then

  CurrTerm = valid_nets->instTerms

)

)

However this does not get me all the cell instances in my current view... (missing certain instances as well as duplicate cellviews) as well, I need to get the name of the connected net from the current instance into the found instance(external net name to internal net name).

Thanks
