title: Getting google search results with Rails
body: <p>I was looking for a way to retrieve Google search results, using RoR.
  I could see that a while ago it used to be done only by scraping the HTML pages (Scruby, Nokogiri, Mecheanize...). I was wondering first, if it's legit, second, I didn't really undesrtand how can you rely on another site's HTML and CSS - what would happen if it's changed in the next day... Maybe I missed something there?
  Then I saw that Google offers an API for doing it, but I couldn't find any Rails plugin that handles it.</p>
  
  <p>Does anybody know any?</p>
  
  <p>Thanks :-).  </p>
