在Go中随机化MongoDB查询的顺序

Question

Here is my query :

c := session.DB("searchV").C("video")
var results []BadVideo
err5 := c.Find(nil).All(&results)
fmt.Println("request done")
if err5 != nil {
    panic(err5)
}
var i = 0
for _,badvideo := range results {
}

I would like to randomize the order of browsing the items of the query for making operation on each item of the request ...

So each time I run it, I browse it in a different order.
