I don't see this scaling: https://deepwiki.com/search/how-is-the-tree-formed-and-tra_9...

I'd do some large scale benchmarks before doubling down on this approach.

A good thing about tree representation compared to a 'list' representation is that you can search hierarchically, layer by layer, in a large tree. For example, AlphaGo performs search in a large tree. Since the scale of retrieval is smaller than that of the Go game, I guess this framework can scale very well.
