Ah - it's a bug in the ElasticSearch module - it modifies the params
hashref it gets passed (as it gets a reference, it's modifying what you
gave it).

In ElasticSearch->new, it passes the params hashref to
ElasticSearch::Transport->new, which includes the following:

    my $servers = delete $params->{servers}
        || '127.0.0.1:' . $transport_class->default_port;
    [...] 
    for (qw(timeout max_requests no_refresh deflate
    max_content_length)) { next unless exists $params->{$_};
        $self->$_( delete $params->{$_} );
    }

Until this problem in ES is fixed, you'll want to take a copy/clone of
the config settings before giving them to ElasticSearch.

A simple way would be e.g.:

    my $elsearch = ElasticSearch->new( 
	{ %{ config->{ElasticSearch} } }
    );
