title: How to retrieve tweets by hashtag without authentication?
body: <p>I need to update my app with Twitter API 1.1.
  Previously I retrieved tweets using following URL: </p>
  
  <blockquote>
    <p><a href="http://search.twitter.com/search.json?tag=ios&amp;rpp=25" rel="nofollow">http://search.twitter.com/search.json?tag=ios&amp;rpp=25</a></p>
  </blockquote>
  
  <p>But now it does not work.
  I tried to use following URL from Twitter API documentation: </p>
  
  <blockquote>
    <p><a href="https://api.twitter.com/1.1/search/tweets.json?q=%23freebandnames&amp;since_id=24012619984051000&amp;max_id=250126199840518145&amp;result_type=mixed&amp;count=4" rel="nofollow">https://api.twitter.com/1.1/search/tweets.json?q=%23freebandnames&amp;since_id=24012619984051000&amp;max_id=250126199840518145&amp;result_type=mixed&amp;count=4</a>. </p>
  </blockquote>
  
  <p>But it returns the following error:</p>
  
  <pre><code>{"errors":[{"message":"Bad Authentication data","code":215}]}
  </code></pre>
  
  <p>How can I retrieve these tweets?</p>
  
  <p>I would like to use Twitter.framework, but any suggestions will be appreciated.</p>
