Find-the-command is a bunch of simple command-not-found hooks, intended for using with pacman, it is primarily targeting Arch-based distros. It uses pacman functionality for searching files, introduced in 5.0 release, so there are no useless pkgfile dependencies.
Interactive shells have an ability to run a specified function when entered command is not found. So these hooks contain a simple function, which is run when shell fails to find any local executables in PATH, aliases and functions matching entered command. There are both interactive hooks, which are providing installation prompt and some other useful functionality (like showing info about package), and 'non-interactive', which are only displaying a package (or list of packages) that provides needed command.
$ git clone https://aur.archlinux.org/find-the-command.git
$ cd find-the-command
$ makepkg -si
Alternatively, you can use yay:
$ yay -S find-the-command
To enable it, you need to source needed file from /usr/share/doc/find-the-command directory according to the shell you use. For example, to enable find-the-command zsh hook, you need to place the following in your ~/.zshrc:
source /usr/share/doc/find-the-command/ftc.zsh
You can also append some options when sourcing file to customize your experience.

It is also necessary to create pacman files database:
# pacman -Fy
There is also systemd timer included to update pacman files database on daily basis, so you don't need to worry about it, just run once the following:
# systemctl enable pacman-files.timer
