title: Setting query string using Fetch GET request
body: <p>I'm trying to use the new <a href="https://developer.mozilla.org/en/docs/Web/API/Fetch_API" rel="noreferrer">Fetch API</a>: </p>
  
  <p>I am making a <code>GET</code> request like this:</p>
  
  <pre><code>var request = new Request({
    url: 'http://myapi.com/orders',
    method: 'GET'
  });
  fetch(request);
  </code></pre>
  
  <p>However, I'm unsure how to add a query string to the <code>GET</code> request. Ideally, I want to be able to make a <code>GET</code> request to a <code>URL</code> like:</p>
  
  <pre><code>'http://myapi.com/orders?order_id=1'
  </code></pre>
  
  <p>In <code>jQuery</code> I could do this by passing <code>{order_id: 1}</code> as the <code>data</code> parameter of <code>$.ajax()</code>. Is there an equivalent way to do that with the new <code>Fetch API</code>?</p>
