That is the whole point of the firebase data structure.

Firebase Not Retrieving TagList

Let us simplify: Firebase: [image] With ProjectBucket = MacTags Taglist returned = ["MoreMacTags", "FA:B7:F7:63:17:C1", "0A:7B:CF:AF:06:F9"] [image] With ProjectBucket = MacTags/MoreMacTags Taglist returned = ["mactag1", "mactag2"] [image]

The tag structure in the 4 year old experimental app is an example of very fine grained data storage, for the game Rock Paper Scissors, capable of managing multiple matches and multiple players.

MultiPlayer Rock Paper Scissors on FireBaseDB

I haven't used Firebase in a while, maybe because the stock MIT emulator was too old to support it.
I can't vouch for the completion of the app, but the important thing to learn from it is how to build up Firebase tags by JOINing key parts separated by '/', avoiding storing lists, and by not worrying about redundant storage.

How to Search any tag in Firebase?

In simplest terms, this should work.... assuming you have no authentication rules setup (so data is read/write=true) say your data structure is like this: users <<top level project bucket |-167981 |-234:"hello" |-176584 |-123:"goodbye" |-158394 |-123:"goodmorning" |-167834 |-345:"goodevening" and you want to return the data associated with the tags 123. You need to go into the rules and set this: "users": { ".read": true,…

Hello, I think I found a different solution, I can simply add a "/" to create a subtag, thank you for your help.
