Dear Monks, I am having huge probelms with HoH. I have a list of files which i would like to process and make the HoH from. 
$refine =1;


use File::Find;

    find(\&wanted, 'upload_profile/');
    sub wanted {
                #/\_$refine/ && print "$File::Find::name\n" && push @a
+rray, $_;
                /predictions\_\Q$refine\E/i && push @found, $_;

                }


####sort array of foud files###

@find = sort { $a cmp $b } @found;

#print "find: @find";


foreach my $file (@find)
{
    print "file: $file\n";
    open (LOOKUP, "<upload_profile/$file") or die $!;

    while (<LOOKUP>)
    {
        ($name, $id) = (split m{\t})[3, 4];
         print "id: $id\n";
        
        $data{$file}{$id} = $name;

    }
      close (LOOKUP);
}

close (LOOKUP);

I want to search the HoH using one of the specific files used to make the HoH. I have another file which i would like to use to search against the HoH which is a list of ids 1-1000. 
$file = 'test_predictions_1';
open (FH, "<EXAMPLE");
while (<FH>) {  $id = $_;
    if (exists $data{$file}{$id}) {print "match\n";}
             }
