Hi guys,

I have a quick question, do you know if mongo can create an index on the following data structure:

    {
        prices: {
            price1: 0.90,
            price2: 0.12,
            price3: 0.13
        }
    }

so I would like to do index like this `ensureIndex({prices:1})` but I am not sure will it include all prices and its values inside.

The reason why I need to lay data this way not the standard Array approach is because I would like to be able to sort based on which price version has been chosen i.e. `sort({prices.price:1})`.

Any ideas?

cheers
