title: how to format the returned data in a riak map/reduce
body: <p>I am trying to get riak to return specific data instead of the keys.</p>
  
  <p>I started with the fasttrack introduction. I can't find a way to retrieve the right data.</p>
  
  <p>I am trying with this query (<a href="http://wiki.basho.com/Loading-Data-and-Running-MapReduce-Queries.html" rel="nofollow">from here</a>):</p>
  
  <pre><code>{"inputs":"goog",
   "query":[{"map":{"language":"javascript",
                    "source":"function(value, keyData, arg) { var data = Riak.mapValuesJson(value)[0]; if(data.High &amp;&amp; parseFloat(data.High) &gt; 600.00) return [value.key]; else return [];}",
                    "keep":true}}]
  }
  </code></pre>
  
  <p>I am trying to retrieve series of objects like <code>{"Date":"YYYY-MM-DD","Open":123,"Close":123,"Volume":12345}</code>.</p>
  
  <p>How can achieve this?</p>
