How can I search a specific data in an array inside of a mongoose database?

Question

var campgroundSchema = new mongoose.Schema({
    likey:{
        numOfLikeys:{
            type:Number,
            default:0
        },
        whoLiked:[{
            id:{
                type:mongoose.Schema.Types.ObjectId,
                ref:"User"
            },
            username:String
        }]
    }
});

I want to search for "username" inside of the whoLiked array. I tried this: Campground.find({ likey.whoLiked.username: req.user.username }, ...);

It should be:

Campground.find({ "likey.whoLiked.username": req.user.username })

Where "likey.whoLiked.username" is wrapped as string to indicate the entire search path.

Make sure req.user.username is an actual valid value as well.
