Error on empty query string

[chuks]

Hi,
Awesome module. I'm currently converting a project from PHP to node.js. In PHP, I can do this $results = $client->Query("",'index'); but this throws an error in limestone, i.e.

limestone.query{'query': "" }j, function(err, response){ -------

any ideas?

I am referring to passing an empty query string to sphinx
