i need to know if there is a way to delete all docs into one collection using nest 2.1.1,

this code:

```auto
elastic.DeleteByQuery<Doc>(del => del
    .Query(q => q
        .QueryString(qs=>qs.Query("*"))
    )
);

```

throw

> Error 6 No overload for method 'DeleteByQuery' takes 1 arguments D:\tfs\Produzione Documentale\MES\Utilities\TestIndiciFisco\TestIndiciFisco\Form1.cs 1509 12 TestIndiciFisco

elastic is ElasticClient  
Doc is the class mapping the index's documents.

thanks,

NEST 2.x contains the methods for [`DeleteByQuery`](https://github.com/elastic/elasticsearch-net/blob/2.x/src/Nest/Document/Multiple/DeleteByQuery/ElasticClient-DeleteByQuery.cs) but [the functionality has been removed from Elasticsearch in 2.x to a separate plugin that must be installed.](https://www.elastic.co/guide/en/elasticsearch/plugins/2.0/delete-by-query-plugin-reason.html)

If you install the plugin with

```auto
bin/plugin install delete-by-query

```

start your cluster and then change your call to

```auto
elastic.DeleteByQuery<Document>(
	"index", 
	typeof(Document), 
	d => d.Query(q => q.QueryString(qs=> qs.Query("*")))
);

```

It'll work as expected.

For deleting all documents in an index though, it'd be much quicker to just delete the index, and create a new one.
