I am trying to search thru 2 arrays for the same string. Record the matching indexes of both search in the same array of results. Then weed out the duplicate results & process the results. Here is the code I've been trying to use. 

&readbksic();
&readbkprm();
$pss = "$in{'productsearch'}";
&productsearchbymodel($pss);
&productsearchbydesc($pss);
@matchlist = (@modelmatches,@descmatches);
my @matches = keys %{ { map {$_=>1 } @matchlist} };
&DisplayHTML('/usr/local/apache/post/invorder.pl/screens/display_produ
+cts_top.html');
foreach $linenumber (@matches){
    $VCD = $BKSIC_MFG[$linenumber];
    $VMN = $BKSIC_MODEL[$linenumber];
    $VPD = $BKSIC_DESC[$linenumber];
    $QOH = $BKSIC_QOH[$linenumber];
    &DisplayHTMLOnly('/usr/local/apache/post/invorder.pl/screens/displ
+ay_products_middle.html');
}
    &DisplayHTMLOnly('/usr/local/apache/post/invorder.pl/screens/displ
+ay_products_bottom.html');
exit;
}
}

sub productsearchbymodel {
    my $modelterms = shift;
    my $modelpattern = join "|", split " ", $modelterms;
    my $modelcase = $in{'case'} eq 'insensitive'?"(?i)":"";
    $modelpattern = qr/$modelcase$modelpattern/;
#    my @modelmatches = grep { /$modelpattern/ } @BKSIC_MODEL; #This w
+ill store the actual matching string
    my @modelmatches = grep { $BKSIC_MODEL[$_] =~ /$modelpattern/ } 0.
+.$#BKSIC_MODEL; #This will store the index ID of the matching array e
+lement.
    return @modelmatches;
}
sub productsearchbydesc {
    my $descterms = shift;
    my $descpattern = join "|", split " ", $descterms;
    my $desccase = $in{'case'} eq 'insensitive'?"(?i)":"";
    $descpattern = qr/$case$pattern/;
#    my @descmatches = grep { /$descpattern/ } @BKSIC_DESC; #This will
+ store the actual matching string
    my @descmatches = grep { $BKSIC_DESC[$_] =~ /$descpattern/ } 0..$#
+BKSIC_DESC; #This will store the index ID of the matching array eleme
+nt.
    return @descmatches;
}

When I perform only 1 search the code works fine. When I try to perform both, no matches are found.
