Deep path query using wildcard as a path

Question

I have data in which I've tried to follow Firebase's advice about flat structure so I'm not pulling more than I need. The net result is I have quotes organised in nodes like this:

quotes -> clientName -> quoteObject

the quoteObjects have a 'dateCreated' value, and I want to be able to pull this data like so (for when I'm pulling one big list of all the quotes for a specific page, I then use object assign to make one big array of objects to display) :

  const quotesRef = firebase.database().ref('quotes');
    quotesRef.orderByChild('dateCreated').on('value', snapshot => {
       // function
    });

Unfortunately the dateCreated value is more than one level deep so the standard query doesn't work. I know you can do a deep path query if you know the parent path, but in my case the clientName parent is always unique. Given this, is it possible to specify a kind of wildcard path? If so how would I go about that? Cheers!

Edit: Showing database example, sorry should have been more specific initially.

quotes
    - ClientEmailOne
        -UniqueQuoteID
            - createdBy: ClientEmailOne
            - dateCreated: 1479255005172
            - email: "[email protected]"
    - ClientEmailTwo
        -UniqueQuoteID
            - createdBy: ClientEmailTwo
            - dateCreated: 1479255005172
            - email: "[email protected]"
     - ClientEmailThree
         -UniqueQuoteID
            - createdBy: ClientEmailThree
            - dateCreated: 1479255005172
            - email: "[email protected]"
        -UniqueQuoteID
            - createdBy: ClientEmailThree
            - dateCreated: 1479255005172
            - email: "[email protected]"
        -UniqueQuoteID
            - createdBy: ClientEmailThree
            - dateCreated: 1479255005172

Answer 1

Firebase will consider children of the location you run the query on. The child you specify to order/filter on can contain a path to a property, but it cannot contain any wildcards.

Update:

With your new data structure it seems that you're trying to query across all clients and across all quotes of each of these clients. There are two wildcards in there ("all clients" and "all quotes" under that), which Firebase's querying model doesn't allow.

Your current model allows querying all quotes for a specific client:

ref.child("quotes").child("ClientEmailOne").orderByChild("dateCreated")

If you want to query all quotes across all clients, you'll need to add a data structure that contains all quotes (irrespective of their client):

allquotes
    -UniqueQuoteID
        - createdBy: ClientEmailOne
        - dateCreated: 1479255005172
        - email: "[email protected]"
    -UniqueQuoteID
        - createdBy: ClientEmailTwo
        - dateCreated: 1479255005172
        - email: "[email protected]"
     -UniqueQuoteID
        - createdBy: ClientEmailThree
        - dateCreated: 1479255005172
        - email: "[email protected]"
    -UniqueQuoteID
        - createdBy: ClientEmailThree
        - dateCreated: 1479255005172
        - email: "[email protected]"
    -UniqueQuoteID
        - createdBy: ClientEmailThree
        - dateCreated: 1479255005172
        - email: "[email protected]"

Then you can query:

ref.child("allquotes").orderByChild("dateCreated")
