title: Extract keyword from Google search in Javascript
body: <p>I'd like to extract from the url of a Google search the keyword of the search (e.g. for the keyword "car" : <a href="http://www.google.com/webhp?hl=en#sclient=psy&amp;hl=en&amp;site=webhp&amp;source=hp&amp;q=car&amp;aq" rel="noreferrer">http://www.google.com/webhp?hl=en#sclient=psy&amp;hl=en&amp;site=webhp&amp;source=hp&amp;q=car&amp;aq</a> ... (here car is between "q=" and "&amp;aq"
  but I noticed that the tokens might change ["&amp;ie" instead of "&amp;aq"]). </p>
  
  <p>Being new at regex and Google search I haven't found so far the solution, does someone know how to do this please ?</p>
