Lucy::Search::PolySearcher - Aggregate results from multiple Searchers.

SYNOPSIS ^

    my $schema = MySchema->new;
    for my $server_name (@server_names) {
        push @searchers, LucyX::Remote::SearchClient->new(
            peer_address => "$server_name:$port",
            password     => $pass,
            schema       => $schema,
        );
    }
