I am using:

sub search {
    my $terms = shift;
    my $pattern = join "|", split " ", $terms;
    my $case = $FORM{case} eq 'insensitive'?"(?i)":"";
    $pattern = qr/$case$pattern/;
   my @matches = grep { $names[$_] =~ /$pattern/ } 0..$#names;
    return \@matches;
}

[download]

in order to find matches in @names. I have tried every way I can think of to make the code search @names and @desc as well. I want the results of both searches stored in the same array. Then I can weed out the duplicates.
