I don't think Ahmad was saying that "rpm doesn't accept
wildcards" at all. Quite the opposite; rpm accepts
wildcards, and has for as long as I can remember.
$ rpm -qa 'pulseaudio*'
pulseaudio-gdm-hooks-11.1-15.fc27.x86_64
pulseaudio-utils-11.1-15.fc27.x86_64
pulseaudio-module-x11-11.1-15.fc27.x86_64
pulseaudio-11.1-15.fc27.x86_64
pulseaudio-libs-glib2-11.1-15.fc27.x86_64
pulseaudio-module-bluetooth-11.1-15.fc27.x86_64

You need to use the -a / --all option when querying with a
glob, e.g. rpm -qa 'foo*' instead of rpm -q 'foo*'.
Whether you prefer to use a glob or pipe to grep is a matter
of preference in most cases. I try to avoid pipes when they
aren't needed out of habit, but the difference in characters
typed or performance is negligable. The rpm globbing
support is quite limited, so if you need a more flexible
search string, then grep wins.
One thing note when passing globs to commands like this is
that it's important to quote or escape the glob to prevent
the shell from expanding it. So either of these work:
rpm -qa 'pulseaudio*'
rpm -qa pulseaudio\*
It also works without the quotes as long as you don't have
anything which matches pulseaudio* in the directory where
you run the command. That lulls many people into complaceny
and then they're surprised when they run it somewhere the
glob is exapnded by the shell and the command behaves
differently. It's a good habit to always protect those
globs from the shell.
