go - Unstructured MongoDB collections with mgo

Question

I'm VERY new to Go. From what I've seen in the examples of mGo, in order to query a collection and then read from it, you have to predefine the data that will be coming back in a struct.

type Person struct {
    ID        bson.ObjectId `bson:"_id,omitempty"`
    Name      string
    Phone     string
    Timestamp time.Time
}

In PHP, the document was assigned to an array. This was perfect as one record may have completely different set of keys (may not contain Name or Phone but contain Email) and I could access it directly without setting up a predefined class / struct / variable.

Is there a way to do the same in Go / mGo?
