`nix search nixpkgs` skip registry update

If you are using flakes on NixOS you can search the nixpkgs that you are using to build your system. This ensures that it is already downloaded because.

Local flake-based `nix search`, `nix run` and `nix shell`

I found a way to set the registry in my flake.nix: { inputs.nixpkgs.url = "github:nixos/nixpkgs/nixos-unstable"; outputs = { self, nixpkgs, ... }@inputs: { nixosConfigurations.foo = nixpkgs.lib.nixosSystem { modules = [ ({ pkgs, ... }: { nix.registry.sys = { from = { type = "indirect"; id = "sys"; }; flake = nixpkgs; }; }) # ... ]; }; }; } Now I can nix search sys foo
