Ember Data Sadness

Request URL:http://192.168.10.200:3000/archives/1
Request Method:GET
Status Code:200 OK

Returns:
archive: {id:1, name:numbers, archive_item_count:60,…}
archive_items: [{id:1278, original_subject:Stack Overflow Careers -- Email Verification,…},…]

EVERYTHING A-OK! List of items displays perfectly in the View. 

AND THEN... Type 'welcome' into the search box which fires this code:

    performSearch: function() {
      var ars;
      if (this.get('searchTerm') === '') {
        return;
      }
      ars = SafeKeepIt.Archive.find({
        id: this.get('content').id,
        search_term: this.get('searchTerm')
      });
      return this.set('model', ars);
    }

SAD TROMBONE ¯\_(ツ)_/¯

Same controller action returning the same JSON packet.
