title: Filter clinical trials based on start date using Python package
body: <p>I am using the <code>clinical trials package</code> (<a href="https://pypi.python.org/pypi/clinical_trials/1.1" rel="nofollow noreferrer">https://pypi.python.org/pypi/clinical_trials/1.1</a>) to fetch data about clinical trials. I would like to restrict the results to those after a certain year (say, 2014). How does one apply such a filter?</p>
  
  <pre><code>results = trials.search(queryString, condition = 'Myeloma', start_date = '&gt;2014',count=500)
  </code></pre>
  
  <p>runs but doesn't restrict the results based on <code>start_date</code>. The start date typically has a <code>Month YYYY</code> format</p>
