Recessively query Redis based on data type - redis

Question

I am representing JSON objects in Redis by flattening the JSON path keys like so:
JSON object
{
"users": [
{
"name": "John Smith",
"address": {
"street": "12 Rainbow Avenue",
"country": "Fuzzyland"
}
}, {
"name": "Billy Bob",
"address": {
"street": "8 Rocky Lane",
"country": "Fraggleville"
}
}
]
}
Redis entries
users // SET [0, 1]
users:0 // SET [name, address]
users:0:name // STRING "John Smith"
users:0:address // SET [street, country]
users:0:address:street // STRING "12 Rainbow Avenue"
users:0:address:country // STRING "Fuzzyland"
users:1 // SET [name, address]
users:1:name // STRING "Billy Bob"
users:1:address // SET [street, country]
users:1:address:street // STRING "8 Rocky Lane"
users:1:address:country // STRING "Fraggleville"
As you can see, for properties that are arrays or object literals I am using a Redis SET to store the available keys.
It is easy enough for me to convert the JSON object to this structure using Node. However I am not experienced enough with Redis to write recursive queries that stitch together a complex result.
For example, say I want to get all the keys and values for users:1. How do I write a query that looks at the value of users:1 sees that it is a SET so uses the values from that as another set of query keys?
