title: How to restrict the language of results in Twitter4j to english?
body: <p>I tried using the <code>setLang(String lang)</code> i.e; --><code>setLang("en")</code> and <code>lang(String lang)</code> i.e; <code>lang("en")</code> methods of the <strong>Query</strong> class. But they are not working.  </p>
  
  <p>Also if I want to use multiple keywords in my search query and should restrict the results to tweets containing <strong>ALL</strong> keywords, what should I do ?</p>
