_find - specifying subfields in array

[Geoff Bomford]

I have a document that looks something  like below.

I can use _find to filter on any of the top level fields, is it possible to 
specify fields, and filters on subfields, if they are in an array? If so, what 
is the syntax?

For example, if I ONLY wanted to output “barcodes.barcode”, instead of all the 
fields in “barcodes” how do I express that in the fields..., and can I specify 
a “barcodes.barcode” value in the selector?

I haven’t been able to find a solution.

Thanks!

    "selector": {
        "type": {"$eq": "Delivery"}
    },
    "fields" : ["_id", "_rev", "type", "orderNumber", “barcodes”],
    "sort": ["type","orderNumber"],
    "limit": 10,
    "skip": 0
}
