title: Using search_full_archive in Tweepy
body: <p>Does anyone know how to use the <code>search_full_archive</code> feature in tweepy module? I used the cursor feature similar to the regular search, but it didn't work.</p>
  <pre><code>import tweepy as tw
  
  api_key = '***'
  api_secret_key = '***'
  access_token = '***'
  access_token_secret = '***'
  
  #Authenticate
  auth = tw.OAuthHandler(api_key, api_secret_key)
  auth.set_access_token(access_token,access_token_secret)
  api = tw.API(auth)
  
  # search tweets
  def get_tweets_full(hashtag):
      tweetObj_full = tw.Cursor(
          self.api.search_full_archive,
          environment_name = 'VolcanicDisaster', # Dev environment label from twitter developer dashboard
          query = hashtag
      )
       return tweetObj
  
  get_tweets(hashtag = '#kilauea')
  </code></pre>
  <p>I get an error stating 'API object has no attribute search_full_archive'. However, if I use the regular search method <code>api.search</code> (with its parameters q) instead of <code>api.search_full_archive</code> it works fine. I want to look back for tweets from 2 years ago and require api_full_search, wondering if anyone knows how to use this feature?
  I have managed set up the premium account (sandbox version - free) with twitter API, but when I input <code>dir(api)</code> I don't see the <code>search_full_archive</code> method in the output list of methods.</p>
