POSTing a nested NSDictionary using AFNetworking 2

Using the Postman extension for Chrome I can successfully POST some JSON. Using Charles to inspect the request, I see that the request data is as follows:

{
  "query": {
    "term": {
      "user_id": "12345"
    }
  }
}

When I try to construct this same request using AFNetworking 2.4.1, I can see that the data is formatted as:

query[term][user_id]=12345

The server of course returns an error.

What part of the POST request am I getting wrong?

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];

NSDictionary *parameters = @{@"query":@{@"term":@{@"user_id":@"12345"}}};

[manager POST:@"http://someURL" parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
        NSLog(@"SUCCESS %@", responseObject);

    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"FAIL: %@", error);
    }];

The short answer is: 

manager.requestSerializer = [AFJSONRequestSerializer serializer];

From the documentation:

Requests created with requestWithMethod:URLString:parameters: & multipartFormRequestWithMethod:URLString:parameters:constructingBodyWithBlock: are constructed with a set of default headers using a parameter serialization specified by this property. By default, this is set to an instance of AFHTTPRequestSerializer, which serializes query string parameters for GET, HEAD, and DELETE requests, or otherwise URL-form-encodes HTTP message bodies.
