    <p>Twitter input node. Can be used to search either:

        <li>all tweets by specific users</li>
        <li>direct messages received by the authenticated user</li>

    <p>Use space for <i>and</i> and comma , for <i>or</i> when searching for multiple terms.</p>
    <p>Sets the <b>msg.topic</b> to <i>tweets/</i> and then appends the senders screen name.</p>
    <p>Sets <b>msg.location</b> to the tweeters location if known.</p>
    <p>Sets <b>msg.tweet</b> to the full tweet object as documented by <a href="https://dev.twitter.com/docs/platform-objects/tweets">Twitter</a>.
    <p><b>Note:</b> when set to a specific user's tweets, or your direct messages, the node is subject to
      Twitter's API rate limiting. If you deploy the flows multiple times within a 15 minute window, you may
      exceed the limit and will see errors from the node. These errors will clear when the current 15 minute window
      passes.</p>
