I noticed two issues with the Package Search system:
The Nix Expression item in the package details all say Not specified. That is too bad because I frequently click on the link to learn from the package Nix files.
I expect to see a commit hash where <nixpkgs> commit is found at the bottom of the search result pages. (It could be that I don’t understand the purpose of <nixpkgs> commit.)
Now look at the very bottom of the same bash search page, where it says <nixpkgs> commit I expect something more like 83df67 commit but I could just be mistaken as to what that is supposed to mean.
