User talk: Makefu

In https://nixos.wiki/wiki/Documentation_Gaps#What_are_setup_hooks.3F

There is a link to https://search.nix.gsc.io/?q=makeWrapper%20%3D&i=nope&files=&repos= which is not loading now. What is the context for this? Can this be changed to use github code search?

And the wording top-level hunting is confusing to me as well. If possible can you update this part?
