The prompt has Elisp mode bindings and a separate history.  M-RET to
start occur.  If you really want everything to be non-interactive

I didn't have this use case in mind.  The current way to do this would
write like

#+begin_src emacs-lisp
(el-search--occur
 (el-search-make-search
  '`(read-string ,(pred stringp) nil ,_ ,t)
  (lambda ()
    (el-search-stream-of-directory-files
     (expand-file-name "~/src/emacs/trunk/lisp")))))
#+end_src

I think.  Do you think this is worth an own defun?
