_changes API not working with filter and view parameter on Couchbase Lite

The _changes document is not clear on the filter and view parameters, in Couchbase Lite. I am trying to query the below url to fetch changes if a document with type order gets added.

_changes?include_docs=true&feed=longpoll&since=0&filter=_view&view=orders%2Forder

This filter=_view&view=orders%2Forder query parameter is the issue, removing the same from the above fetches all the documents

Using the above gives a 404 on Couchbase Lite but the same works on CouchDB. Response:

{
    status: 404,
    error: "not_found"
}

Here is my _design/orders

{
     "_id": "_design/orders",
     "language": "javascript",
     "views": {
          "order": {
               "map": "function(doc) {if(doc.type && doc.type == 'order') {emit(doc.oID, doc);}}"
           }
      }
}

Please can any one share a syntax or example on how to pass the design document and/or view in _changes API to get a filtered output.

Everyone who finds this, I think the answer could be changing the filter itself and the query string like this:

Filter:

{
 "_id": "_design/orders",
 "language": "javascript",
 "filters": {
      "order": "function(doc) {if(doc.type && doc.type == 'order') {emit(doc.oID, doc);}}"
  }
}

and the query string:

_changes?include_docs=true&feed=longpoll&since=0&filter=orders/order
