I seek wisdom in regards to referencing an assigned scaler variable - $search_line = $fields{'keywords'}; and a 2nd scaler variable which performs the same funtion - $search_line2 = $fields{'keywords'};. The 2nd variable must not eliminate the value of the first, but include the same assignment from a different file. Initially, I need to separate the return results of search_line and search_line2. The initial assignment opens 2 files (by design) Assignment: 
foreach $item (@resultline, @premium_resultline)

open (SIDX, "$data_dir/search.idx");
open (SIDX2, "$data_dir/search2.idx");

then pulls in 2/both files for reading/search simultaneously: 

(@skeyw) = split(/ /,$search_line);

if ($file_locking ne "No"){flock (SIDX, LOCK_SH) or die "Can't set loc
+k for file: $data_dir/search.idx, $data_dir/search2.idx $!\n";}
    while($line3 = <SIDX>)
    {

    $line2 = <SIDX2>;
    $sline = "${line1}${line2}${line3}";
    
    
    foreach $kwr (@skeyw)
        {

        if (($sline =~ /$kwr/i) and ($kwr ne "")) 
        {
                
            $toadk = "true";
            }
            
        }

        if ($toadk eq "true")
            {
            $premium_resultline[$icnt] = "${line2}";
            $resultline[$icnt] = "${line3}";
            
        #    $resultline[$icnt] = "${line1}${line2}${line3}";


            $toadk = false;
            $icnt++;
            }

    }
    
    
     #if ($file_locking ne "No"){flock (CIT, LOCK_UN);}
close (SIDX);
close (SIDX2);
}

I am thinking this for logic reasons: $search_line = $fields{'keywords'}; $search_line2 = $fields{'keywords'}; 
(@skeyw) = split(/ /,$search_line);
(@skeyw) = split(/ /,$search_line2);

[download]
However this does not allow for logic since I need the @skeyw to split itself once yet recognize that SIDX and SIDX2 are separate files. The search result return is: 

sub get_search_ready
{
my ($search_line) = @_;
my ($search_line2) = @premium_resultline;

$reline = $search_line;
$reline = $search_line2;

$reline =~ s/[+\[\]()*^.\$?\\~<>;]//g;

return ($reline);
}
