Replacement for DeletebyQuery in NEST V2.0.4

My earlier version of NEST used to support the following code for DeleteByQuery

ESClient.DeleteByQuery<object>(q => q.Query(q1 => q1.QueryString(qs => qs.Query("*"))));
Now, that the nugetPackage of NEST elastic version has changed to 2.0.4, I am unable to work using the existing code. Could anyone please let me know what could be replacement for it. My Elastic Search is version 1.5.1
