APT's built in search isn't always as helpful as it could be, which is what I think "Add new software" will be using to do the search. That's a Debian thing, rather than being specific to RPi. Fortunately, there's an alternative that often gets you there quickly, Google. Search Google for "debian file roller", and the Debian file-roller package is the first hit, which I'm guessing is the package you want. Once you have the package name, just "sudo apt update && sudo apt install package-name" (or the equivalent through the GUI).
You can also use the search on https://packages.debian.org/
