Newbie question: How to disable pager in "guix search"?

1 The problem
=============

  Most of the times, I use shell-mode in Emacs and execute "guix"
  commands. When I execute "guix search", the following warning is shown

  ,----
  | guix search emacs
  `----

  ,----
  | WARNING: terminal is not functional
  | Press RETURN to continue
  `----

  I think the reason why this happens is that the command tries to use a
  pager which is not possible in shell-mode.

  I need to press C-c C-c to exit the command which is time-consuming
  and doesn't allow me to normally search a buffer as I would normally
  do it in Emacs.

  I'd rather guix did not use a pager and instead show all the results
  in raw text since that way I can scroll up and search within Emacs.


2 The question
==============

  How could I disable the pager in "guix search" and make it display the
  output in raw text?

I asked the same question in <irc://irc.libera.chat/#guix> and someone
recommended me setting PAGER to an empty value I did by executing the
following command

,----
| export PAGER=
`----

This solved the issue. Someone also recommended me setting the `PAGER'
environmental variable in my Emacs configuration and shared his personal
configuration which contained the following statements

,----
| (setenv "EDITOR"         "emacsclient")
| (setenv "GIT_EDITOR"     "emacsclient")
| (setenv "MANPATH"        (getenv "MANPATH"))
| (setenv "PAGER"          "cat")
| (setenv "PATH"           (getenv "PATH"))
| (setenv "PROMPT_COMMAND" "")
| (setenv "SHELL"          (getenv "SHELL"))
| (setenv "TERM"           (getenv "TERM"))

I keep the small Guile script below in ~/.config/editor/always-emacs
and set EDITOR to that (in init.el).

Kind regards
Felix Lechner

#!/usr/bin/env guile
!#

(let* ((arguments (cdr (command-line)))
       (inside-emacs (getenv "INSIDE_EMACS"))
       (emacs-command (if (string-contains (or inside-emacs "") "comint")
              (append '("emacsclient") arguments)
              (append '("emacsclient" "--create-frame") arguments))))
  (apply execlp emacs-command))

That's cool, I didn't know about this solution. Nevertheless, I'd like
to share the ones I've been using so far.

1. It's possible to just pipe the command throught `cat`, e.g.

    guix search python | cat

2. A fully functional terminal can be opened inside emacs with
   `M-x ansi-term`. It has a drawback that it killing and yanking
   requires swithing the buffer to line mode (`C-x C-j`) and then back
   to char mode (`C-c C-k`). But it's otherwise perfect for invoking
   programs that expect a smart terminal :)
