You can search for packages in Arch Linux using the pacman package manager. To search for a specific package, you can use the following command:
$ pacman -Ss <package_name>
Replace <package_name> with the name of the package you’re searching for. The -Ss option tells pacman to search for packages that are either installed or available in the repository. The output of the command will show a list of packages that match your search query.
If you want to search for a package that contains a specific keyword in its name or description, you can use the following command:
$ pacman -Ss <keyword>
Replace <keyword> with the keyword you’re searching for. The output will show a list of packages that contain the keyword in their name or description.
