Could you please help me to develop this, I have tried the Thread::Queue. It takes too much time to retrieved the result from a source and I have to search more than 50 sources at a time. There could be more than 10 instances that would be running concurrently.
How can main thread can read them off and display>
following is the code I am using 
sub run_search {
    my ($self, $searches, $search_string, $site, $max_hits, $from_year
+, $to_year) = @_;
    my $Qwork = new Thread::Queue;
    my $Qresults = new Thread::Queue;
    my $THREADS = scalar(keys %$searches);
    my @return;
    foreach my $obj (values %$searches) {
        eval {
            $obj->from_year($from_year);
            $obj->to_year($to_year);
            $obj->parse_search();
        };
        if ($@) { 
            print STDERR "problem2 $@\n"; 
        }        
        $Qwork->enqueue($obj);
    }
    
    $Qwork->enqueue( (undef) x $THREADS );
        
    my @pool = map{
        threads->create( \&parallel_search, $Qwork, $Qresults, $max_hi
+ts, $self->nuc_code)
    }1 .. $THREADS;
    
    for(1..$THREADS){
        while( my $result = $Qresults->dequeue ){
              push(@return, $result);
         }
    }
        
    ## Clean up the threads
    $_->join for @pool;
    
    return(\@return);

}

        'require ' . ref($work) . ';';
        $work->max_hits($max_hits);
        $result{$work->resource_id} = $work->get_search_results($work-

        $Qresults->enqueue( \%result );
