Sorry I misinterpreted.

I understand even if this one is the wrong example. :-)
It even deserves an entry in the manual.
Well, but I understand what you mean.

The question is: why do you type 'gpg'?

I mean, the upstream name is really GnuPG so it is not one "stupid"
Guix devs arbitrary rename because in their infinite wisdom they
decided to. ;-)

Well, do you type 'gpg' because
a) it is the name of the binary?
or b) it is the name of the package in your previous favourite distro?

If it is a), then a proposal by Pierre named "filesearch" is floating
around.  And this should improve the situation.

If it is b), then I do not see how to improve the situation in the
general case.  But maybe there is some well-known cases.

I agree.  From my point the issue is that "guix search" is not doing
the job and the improvement should come from this.  And your 'gpg'
example is a good one, IMHO:

The expected package 'gnupg' appears... piouf!

I fully agree that the experience with "guix search" is frustating.
And maybe using both the 'upstream-name' and an extra 'properties'
such as 'alternative-names' or 'extra-keywords' should help for
discoverability.


WDYT?

All the best,
