Hi,

mikadoZero reported a bug here:

https://lists.gnu.org/archive/html/help-guix/2019-04/msg00206.html

The bug is reproducible.  On Guix commit
aa7cdc57dc28673dedfc6ec210974aaa0099a419, a search for keyword "cargo"
does not find the "cargo" output of the "rust" package:

--8<---------------cut here---------------start------------->8---
$ guix package --search=cargo
name: chromium-bsu
version: 0.9.16.1
outputs: out

It should have printed all the "rust" packages, and the "mrustc"
package, since each of them has a "cargo" output.  Example:

--8<---------------cut here---------------start------------->8---

version: 1.34.0
outputs: out doc cargo

The general problem here is that Guix does not include outputs whose
name matches the given regex.  One might argue that we should simply add
the output's name to a searchable field, like the description, in cases
like this, but if it's easy to fix, we should just fix it.
