title: YouTube API - Querying by publish date
body: <p>I'm writing a webapp that uses the YouTube Code API to do specific types of searches.  In this case, I'm trying to search for all videos that match a query, and which were uploaded between two dates. <a href="http://code.google.com/apis/youtube/2.0/developers_guide_protocol.html#Displaying_a_list_of_videos" rel="noreferrer">This document</a> says I can use published-min and published-max parameters, while <a href="http://code.google.com/apis/gdata/docs/2.0/reference.html" rel="noreferrer">this one</a> says I can use updated-min and updated-max. </p>
  
  <p>Both of these parameter sets cause YouTube to return an error:</p>
  
  <ul>
  <li><a href="http://gdata.youtube.com/feeds/videos?q=test&amp;published-min=2011-04-05T00:00:00-06:00&amp;published-max=2011-04-14T00:00:00-06:00&amp;max-results=50" rel="noreferrer">published-min</a> returns "This service does not support the 'published-min parameter"</li>
  <li><a href="http://gdata.youtube.com/feeds/videos?q=test&amp;updated-min=2011-04-05T00:00:00-06:00&amp;updated-max=2011-04-14T00:00:00-06:00&amp;max-results=50" rel="noreferrer">updated-min</a> returns "This service does not support the 'updated-max' parameter"</li>
  <li><a href="http://gdata.youtube.com/feeds/videos?q=test&amp;max-results=50" rel="noreferrer">With neither</a> returns a correct result set.</li>
  </ul>
  
  <p>How can I limit my result set to hits within a specified date range?</p>
