When I use search query its returning a hash value reference. I am decoding it with deference

But later I cant able to access the 'formula' variable in the below mentioned hash. 
 $VAR1 = {
          '_source' => {
                         'sheets' => {
                                       'sheet1' => {
                                                     'Sheet_Name' => '
+Ex-Sheet',
                                                     'formulates' => [

+'0' => {

my %doc = %{ $doc };

foreach my $sheet (keys %{ $doc{'_source'}{'sheets'} })
{
    foreach my $columns (@{ $doc{'_source'}{'sheets'}{$sheet}{'formula
+tes'} })
    {
        my %columns = %{ $columns };
        foreach my $one (keys %{ $columns })
        {
            #print $doc{'_source'}{'sheets'}{$sheet}{'formulates'}{$co
+lumns}->{$one}{'formula'},$/;
                        #print $doc{'_source'}{'sheets'}{$sheet}{'form
+ulates'}{$columns}{$one}{'formula'},$/;
                        ### I want to replace the formula variable her
