title: Tweepy: Find all tweets in a specific language
body: <p>I'd like to extract all tweets in the Arabic language in all countries. </p>
  
  <p>I modified the code in this<a href="https://www.karambelkar.info/2015/01/how-to-use-twitters-search-rest-api-most-effectively./" rel="nofollow noreferrer"> tutorial</a>.
  This is my search query. 
  <code>api.search(q="*", count=tweetsPerQry, lang ['ar'],tweet_mode='extended')</code>.  I expect to find a very large number of tweets, but I only collected about 7000 tweets. </p>
  
  <ul>
  <li>I checked the content of some of them and I noticed that they are posted in my country even I did not specify the location/Country (<strong>Can anyone explain why this happen??).</strong></li>
  </ul>
  
  <p>I tried to know the reason for finding a limited number of tweets, so I modified the query by replacing the <em>lang</em> parameter by <em>geocode</em> to find tweets in a city.  I fetched more than 65,000 Arabic tweets. After that, I used the <em>lang</em> parameter with the <em>geocode</em> and I found a very limited number of tweets.</p>
  
  <ul>
  <li>Can anyone help me to know <strong>why I'm not able to get a large number of tweets when I used <em>lang</em> parameter?</strong> </li>
  </ul>
