Elasticsearch 0.90.* and earlier

The current version of the client supports the Elasticsearch 1.0 branch by default, which is not backwards compatible with the 0.90 branch.

If you need to talk to a version of Elasticsearch before 1.0.0, please use Search::Elasticsearch::Client::0_90::Direct as follows:

    $es = Search::Elasticsearch->new(
        client => '0_90::Direct'
    );
