Определить поисковую фразу по которой пришел посетитель. Perl

Появилась задача определить по какой поисковой фразе пришел посетитель на сайт из поисковых систем (Yandex, Google, Mail.ru и т.п.).

Готовых компонентов на Perl я не нашел, да и на форумах примеры в основном на PHP и все в качестве “набросков”.

Пособирав информацию, получился простой компонент. Возможно он будет полезен. Список поисковых систем заимствован отсюда

Как использовать:

use Parse::SEKeywords;

my $key = get_se_keyword( $ENV{'HTTP_REFERER'} );
print "Keyword: ".$key."\n";

my ($key, $se) = get_se_keyword( $ENV{'HTTP_REFERER'} );
print "Keyword: ".$key."\n";
print "Search Engine: ".$se->{name}."\n";

use Parse::SEKeywords;

my $key = get_se_keyword( $ENV{'HTTP_REFERER'} );

print "Keyword: ".$key."\n";

my ($key, $se) = get_se_keyword( $ENV{'HTTP_REFERER'} );

print "Keyword: ".$key."\n";

print "Search Engine: ".$se->{name}."\n";
