title: Python google search explicit phrase
body: <p>I am trying to define a google search with the AJAX interface using the very good function described here (A Martelli)
  <a href="https://stackoverflow.com/questions/1657570/google-search-from-a-python-app">Google Search from a Python App</a></p>
  
  <pre><code>........
  query = urllib.urlencode({'q': searchfor}) 
  ....
  </code></pre>
  
  <p>If I define the variable <code>searchfor = "big car"</code>, the query generated is big+car. However I want to generate the query "big car" (those two words ocurring together).</p>
  
  <p>Q1) That is, I would like to define an explicit phrase in my query (in google I would enter the "phrase" within double quotes). </p>
  
  <p>Q2) How can I define a query where I wxclude a certain term. (In google you enter the "-" sign).</p>
