Iterating through OpenLayers 3 clusters in cluster source

Using OpenLayers 3 (a JavaScript library I'm using to display objects on a map), I have a cluster source defined this way:

(...)
var vectorSource = new ol.source.Vector();
var clusterSource = new ol.source.Cluster({
                distance: 20,
                source: vectorSource
            });
(...)

When I build a new feature I add it to vector source this way

vectorSource.addFeature(myFeature);

My request includes an additional property which is the object they are related to. Each of these objets have their ownid.

myFeature.linkedObject = myObject;

Where myObject.id is the object's id.

To say it in other words, I manage my objects and their features and let the "cluster source" manage and render clusters.

What I need now is to be able to browe through existing clusters to find which one contains the object matching some id.

How can I get a list/array of the currently existing clusters?

Something equivalent to

var clusterSource = new ol.source.Cluster(...);
**var clusters = clusterSource.getClusters();**

which by the way doesn't exist.

Cluster sources have a getFeatures() function.

clusterSource.getFeatures();
