The following example gets information from three sources: Google, MSN and Yahoo!. You would need to create a custom parser for each engine. You may wish to look at HTML::Parser for this. 

#! /usr/bin/perl -w
use strict;
use warnings;

use LWP;
use threads; 
use Thread::Queue;

my $query ="perl";

my $dataQueue = Thread::Queue->new;

my $threadCount = 0;

while (<DATA>)
{
    chomp; s/^\s+//; s/\s+$//;
    my ($engine, $url) = split /\s+/;
    next unless $url;
    $url.=$query;
    print "$url\n";
    my $thr = threads->new(\&doSearch, $engine, $url);
    $thr->detach;
    $threadCount ++;
}

while ($threadCount)
{
    my $engine = $dataQueue->dequeue;
    my $content = $dataQueue->dequeue;
    print "$engine returned: $content\n";
    $threadCount --;
}

print "Parse and return remaining content\n";

sub doSearch
{
    my $engine = shift;
    my $url = shift;
    
    my $ua = LWP::UserAgent->new;
    $ua->agent('Mozilla/5.0');
    $ua->timeout(10);
    $ua->env_proxy;
    
    my $response = $ua->get($url);
    
    if ($response->is_success) {
        $dataQueue->enqueue($engine, $response->content);
    }
    else {
        $dataQueue->enqueue($engine, $response->message);
    }
}
