Thanks for checking this out Michael.  I decided to write an emacs lisp
function which I keybind and which prompts for the variable, and then
launches notmuch-search with that:

(defun ec/notmuch-search-dossier ()
  "Zoek mails van een dossier"
   (let* ((dossier (read-no-blanks-input "Dossier:"))
          (zoek (concat "tag:/" dossier "/")))
          (notmuch-search zoek nil nil nil nil))))

This works like a charm ;) Well, I am of course open to enhancement

Also I upgraded my OS to fedora36 and now I use the standard notmuch
package instead of compiling it myself.  So I don't have sexp support
anymore and therefor I am moving the squeries I added to my notmuch
config into emacs lisp functions.
