title: How to send a Parse Push notification to a specific user
body: <p>I'm trying to make a Cloud code to send a Push Notification to a specific user. </p>
  
  <p>The Parse user can have several installations.</p>
  
  <p>I want to send the notification only to the First created User. I'm writing this cloud code function, but it seems to send push notifications to all the installation files and not to the recent one.</p>
  
  <pre><code>var query = new Parse.Query(Parse.Installation);
      var fromUser = new Parse.User({id:request.params.userId});
      query.equalTo("user", fromUser);
      query.equalTo("channels", "main");
      query.descending("createdAt");
      query.first({
      success: function(installation)
      {
  
       var device = installation.get("deviceType")    
       if (device == "ios") {
                  Parse.Push.send({
        where : query,
        data : {
        title : title,
        alert: alert,
        sound : "chime", 
        badge: "Increment",
            }
  
        }, { success: function() { 
        response.success("Success");
        }, error: function(err) { 
         response.error(err);
        }
  });   
  </code></pre>
