Amending your code:

$search_term = $FORM{'search'};

I'm resisting doing more than you need to this, but I also think you should:

• use strict; (ie declare all variables)
• use qq(interpolated text) quotes so you don't have to escape \" chars (see above) and, similarly, change your delimiter on your match (this will mean you must start it with 'm' though - see my example below)
• slurp file in (see below)

And look at these lines and see if they click?

...
open(FILE, $file);
$file_contents = join '', (<FILE>);
close (FILE);

$file_contents =~ m|<title>(.*?)</title>|is;
my $title = $1;

if ($file_contents =~ m|$search_term|is) {
  push @match, qq(<A HREF="$file">$title</A><BR>\n);
}
[download]

The 's' modifier basically says "search the whole page in one go rather than line by line". The 'i' modifier says ignore case (title == TITLE == TiTLe etc)

If you start the match with an m, you can change the delimiter, making it easier to read (Ie you don't have to escape /). Similarly for s|one|two|is;
