How can I recover the object of my database in Firebase if I do not know which node it belongs to?

I have a database in Firebase for products. I have the following nodes: 

+ Vinos
  "5000" {}
  "5001" {}

+ Quesos
  "6000":{}
  "6001"{}

In my component I only have the code and I need to recover it but I do not know which node it belongs to, would I have to search in all of them?

my database looks like this: Company  - Wines    - 5000       price: 32.90       Product: Flasca 500ml.       Container: Glass    - 5001       price: 20.05       Product: Flasca 100ml       Container: Glass  - Cheese    -6000       price: 19.90       Product: Aged cheese       container: ""

If I have the code 5000 for example in my component and would like to find it to obtain the data, I do not know the node to which it belongs, so I can not put db.ref ('Wines') or db.ref ('Cheese') ). how can I do it? Go through all the nodes and look for it ????

It would be good to know if it is database or firestore, in the case of database what you can do is: 

db.ref('Vinos').equalTo('5000');

or cheeses, in the case of firestore: 

db.collection('Vinos', ref => ref.where ('miValor', '==', '5000'));

I hope it's helpful
