title: YouTube API v3 Search not returning all videos
body: <p>I'm trying to retrieve all videos for a channel, and some are not being returned by the api. I cannot find anything in the spec that indicates why some would not be in the result set. </p>
  
  <p>The call I'm making is:</p>
  
  <pre><code>https://www.googleapis.com/youtube/v3/search?type=video&amp;key=__key_here__&amp;channelId=UCxS2lX7728bTnmK1t21bYlA&amp;part=id,snippet&amp;maxResults=50&amp;order=title
  </code></pre>
  
  <p>[To test this you'll need <a href="https://developers.google.com/youtube/v3/getting-started" rel="nofollow noreferrer">your own api key]
  </a></p>
  
  <p>The first page of results is missing at least one video. The one from 8-15-2018, titled <a href="https://www.youtube.com/watch?v=zRaFy_7cmUY" rel="nofollow noreferrer">I LEARNED HOW TO DO A NEW TRICK!</a>, which is located here, is not in the result set, even though it falls within the date range, and the first 50 results.</p>
  
  <p>Does anyone know if this is a known issue? </p>
  
  <p>I have verified that if I add the q parameter, with the video id, it will retrieve it.</p>
