Missing support for Field Collapsing?

[StefanGla]

Hello, I wonder if the elastica package already supports field collapsing?

https://www.elastic.co/guide/en/elasticsearch/reference/5.6/search-request-collapse.html#search-request-collapse

If not, how can I add these collapse-parameters to my query?

@StefanGla You should be able to use setRawQuery to set the params: http://elastica.io/api/latest/classes/Elastica.Query.html#method_setRawQuery But it would be pretty nice to add support for it with functions.
