+Normally if you run `nix search <package>` it will complain about something experimental.
+<!--more-->
+Assuming you read the message and understand what you are getting yourself into, follow the instructions to enable search. Alternatively, you can search on [https://search.nixos.org/](https://search.nixos.org/).
+
+
+Put the following in `~/.config/nix/nix.conf`
+```
+experimental-features = nix-command flakes
+```
+
+Now search will work but it will rebuild cache every time you search. To avoid building cache, run `nix registry pin nixpkgs`.
+
+
+Search packages with `nix search nixpkgs <package>`.
