R""(
**Note:** this command's interface is based heavily around [*installables*](./nix.md#installables), which you may want to read about first (`nix --help`).
# Examples
* Show all packages in the `nixpkgs` flake:
```console
# nix search nixpkgs ^
* legacyPackages.x86_64-linux.AMB-plugins (0.8.1)
A set of ambisonics ladspa plugins
* legacyPackages.x86_64-linux.ArchiSteamFarm (4.3.1.0)
Application with primary purpose of idling Steam cards from multiple accounts simultaneously
…
```
* Show packages in the `nixpkgs` flake containing `blender` in its
name or description:
```console
# nix search nixpkgs blender
* legacyPackages.x86_64-linux.blender (2.91.0)
3D Creation/Animation/Publishing System
```
* Search for packages underneath the attribute `gnome3` in Nixpkgs:
```console
# nix search nixpkgs#gnome3 vala
* legacyPackages.x86_64-linux.gnome3.vala (0.48.9)
Compiler for GObject type system
```
* Show all packages in the flake in the current directory:
```console
# nix search . ^
```
* Search for Firefox or Chromium:
```console
# nix search nixpkgs 'firefox|chromium'
```
* Search for packages containing `git` and either `frontend` or `gui`:
```console
# nix search nixpkgs git 'frontend|gui'
```
* Search for packages containing `neovim` but hide ones containing either `gui` or `python`:
```console
# nix search nixpkgs neovim --exclude 'python|gui'
```
or
```console
# nix search nixpkgs neovim --exclude 'python' --exclude 'gui'
```
# Description
`nix search` searches [*installable*](./nix.md#installables) (which can be evaluated, that is, a
flake or Nix expression, but not a store path or store derivation path) for packages whose name or description matches all of the
regular expressions *regex*. For each matching package, It prints the
full attribute name (from the root of the [installable](./nix.md#installables)), the version
and the `meta.description` field, highlighting the substrings that
were matched by the regular expressions.
To show all packages, use the regular expression `^`. In contrast to `.*`,
it avoids highlighting the entire name and description of every package.
> Note that in this context, `^` is the regex character to match the beginning of a string, *not* the delimiter for
> [selecting a derivation output](@docroot@/command-ref/new-cli/nix.md#derivation-output-selection).
# Flake output attributes
If no flake output attribute is given, `nix search` searches for
packages:
* Directly underneath `packages.<system>`.
* Underneath `legacyPackages.<system>`, recursing into attribute sets
that contain an attribute `recurseForDerivations = true`.
