To a (limited) degree, that's what apropos does - a program that's been
around since the dawn of Unix (approximately). Admittedly, it only works
for programs you already have installed - but so does "man".

Of course, you get exactly the same ability in any of the package management
tools, or "apt:/search?firewall" (you need kio_apt installed for that),
with the advantage of it searching the repositories for programs that you
don't have installed.

Probably not to the degree you'd like (not to the degree _I'd_ like!) but
these are the basic tools.
