title: YouTube API V3 search, related videos sort order doesn't work
body: <p>When searching for related videos using the YouTube API V3 the sort order doesn't seem to work?</p>
  
  <p>E.g.
  <a href="https://www.googleapis.com/youtube/v3/search?part=snippet&amp;maxResults=50&amp;order=date&amp;relatedToVideoId=moSFlvxnbgk&amp;type=video&amp;key=" rel="nofollow">https://www.googleapis.com/youtube/v3/search?part=snippet&amp;maxResults=50&amp;order=date&amp;relatedToVideoId=moSFlvxnbgk&amp;type=video&amp;key=</a>{YOUR_API_KEY}</p>
  
  <p>and</p>
  
  <p><a href="https://www.googleapis.com/youtube/v3/search?part=snippet&amp;maxResults=50&amp;order=viewCount&amp;relatedToVideoId=moSFlvxnbgk&amp;type=video&amp;key=" rel="nofollow">https://www.googleapis.com/youtube/v3/search?part=snippet&amp;maxResults=50&amp;order=viewCount&amp;relatedToVideoId=moSFlvxnbgk&amp;type=video&amp;key=</a>{YOUR_API_KEY}</p>
  
  <p>both return the same result.</p>
  
  <p>Bug or am I missing something?</p>
