I want to make an API call for searching that looks like this:

https://myapi.com/search/<query>/<token>

where query is the search term and token (optional) is an alphanumeric set of characters which identifies the position of my latest batch of results, which is used for infinite scrolling.

This call returns the following JSON response:

{
  "meta": { ... },
  "results" {
    "token": "125fwegg3t32",
    "content": [
      {
        "id": "125125122778",
        "text": "Lorem ipsum...",
        ...
      },
      {
        "id": "125125122778",
        "text": "Dolor sit amet...",
        ...
      },
      ...
    ]
  }
}

content is an array of (embedded) items that I'm displaying as search results. My models look like this:

App.Content = Em.Model.extend({
  id: Em.attr(),
  text: Em.attr(),
  ...
});

App.Results = Em.Model.extend({
  token: Em.attr(),
  content: Em.hasMany('App.Content', {
    key: 'content',
    embedded: true
  })
});

In order to make that API call, I figured I have to do something like this:

App.Results.reopenClass({
  adapter: Em.RESTAdapter.create({
    findQuery: function(klass, records, params) {
      var self = this,
          url = this.buildURL(klass) + '/' + params.query;

      if (params.token) {
        url += '/' + params.token;
      }

      return this.ajax(url).then(function(data) {
        self.didFindQuery(klass, records, params, data);
        return records;
      });
    }
  }),
  url: 'https://myapi.com/search',
});

then somewhere in my routes do this:

App.Results.fetch({query: 'query', token: '12kgkj398512j'}).then(function(data) {
  // do something
  return data;
})

but because the API returns a single object and Em.RESTAdapter.findQuery expects an array, an error occurs when Ember Model tries to materialize the data. So how do I do this properly? I'm using the latest build of Ember Model.

By the way, I'm aware that it would be much more convenient if the API was designed in a way so I can just call App.Content.fetch(<object>), which would return a similar JSON response, but I would then be able to set the collectionKey option to content and my data would be properly materialized.
