ModuleNotFoundError: No module named 'haystack.nodes'

[GivAlz]

Hi everyone,
I was trying to see if it is possible to collect multiple outputs (I was thinking retrieved documents + generated answer), while doing so I ended up on this page of the documentation:

Route Documents

Essentially the code snippet fails because there is no "add_node" method.

I'm using haystack v 2.2.4 (installed via pip) and I'm referring to the documentation for haystack v2.

@GivAlz nodes are Haystack 1.x artifact. In the above document note how the path and the button in the top left corner indicate version 1.25. Switch this toggle to the latest 2.x release v2.5 and see how this could be done in v2.

Btw you install haystack with pip install haystack-ai
