If I have this schema...

person = {
    name : String,
    favoriteFoods : Array
}

... where the favoriteFoods array is populated with strings. How can I find all persons that have "sushi" as their favorite food using mongoose?

I was hoping for something along the lines of:

PersonModel.find({ favoriteFoods : { $contains : "sushi" }, function(...) {...});

(I know that there is no $contains in mongodb, just explaining what I was expecting to find before knowing the solution)
