Agreed.  Several years ago, I was pleased when debtags came along.  But
let=E2=80=99s face it: People are used to just typing random keywords in a =
box,
rather than having to think about the syntax and semantics of tags, and
finding the right tags to look for.

I think =E2=80=98guix package --search=E2=80=99 works OK for the general ca=
se,
esp. since its output can be piped to recutils or grep if you really
want to filter the search results.

Now, I understand that an operation like listing all bioinfo packages is
not that simple.  Currently it can be achieved by filtering based on the
=E2=80=98location=E2=80=99 field:

  guix package -s . | recsel -p name -e 'location ~ "bioinformatics"'

But then again the same goes for =E2=80=9Clisting all the PDF readers=E2=80=
=9D, etc.

WDYT?
