Re^2: howto map/grep a complex structure

[NetWallah]

You are SEARCHING (grep) not TRANSFORMING (map), so map is not necessary.

Here is a one-liner that works, but I would not recommend writing unreadable code like this.

print for 
   grep { 
      grep {$search eq $_ } @{$href->{$_}->{member}}
   }  keys %$href;
