I'm using NEST/ElasticSearch 5.4 and I am trying to write a NEST object which uses collate.  
Basically i want to have json something like this:

```
 "collate": {
      "query": {
        "lang" : "my_own_language",
        "inline" : "my_scripting_code"
      },

```

Elasticsearch version:5.4

But, when i try to build a NEST object for above query, I am unable to add "Lang'' node for collate query.

```
 .Collate(c => c
              .Query(q => q
                      .Inline("my_scripting_code")
                      .Lang("my_own_language")
                          )
              .Prune()
)

```

Adding **.Lang("my\_own\_language")** throws error.  
Is there any way to add language type for collate queries?

Thanks,  
Ishita
