Fixed my issues with the MacOS Spotlight search

The problem I was actually having was with the operating system
configuration, but in the process of cleaning up the code, I made it
easier to read.

** Searching
On the Mac, we need to change the =locate= command:
#+begin_src emacs-lisp
(when (equal system-type 'darwin)
(setq locate-command "mdfind"))
#+end_src
Now that my paragraphs in an org file are on a single line, I need this less, but being able to use an /indexed search system/, like [[https://ss64.com/osx/mdfind.html][mdfind]] on Macos, or [[https://www.lesbonscomptes.com/recoll/][recoll]] on Linux, gives better results that line-oriented search systems, like =grep=. Lets create operating-system functions the command line for searching:

This function calls these operating-system functions, but returns the matching files as a /single string/ (where each file is wrapped in single quotes, and all joined together, separated by spaces. This function also allows me to /not-match/ backup files and whatnot.
And lets see how that works:
#+begin_src emacs-lisp :tangle no :results replace
(ha-search-notes--macos "crossway stream" "~/Notes")

Lets see it in action:

The =ha-search-notes= function prompts for the phrase to search, and then searches through the =org-directory= path to acquire the matching files. It then feeds that list to =grep= (and the [[help:grep][grep function]] in order to display a list of matches that I can jump to.
Returns this string:
#+begin_example
"'/Users/howard.abrams/Notes/Sprint-2022-25.org' '/Users/howard.abrams/Notes/Sprint-2022-03.org' '/Users/howard.abrams/Notes/Sprint-2020-45.org' '/Users/howard.abrams/Notes/Sprint-2022-09.org' '/Users/howard.abrams/Notes/Sprint-2022-05.org' '/Users/howard.abrams/Notes/Sprint-2022-01.org' '/Users/howard.abrams/Notes/Sprint-2022-19.org'"

Eventually, I would like to change the output so that the title of the Org mode is displayed instead of the first match, but that is good enough.
Add a keybinding to the function:
#+begin_src emacs-lisp
(ha-leader "f n" '("find notes" . ha-search-notes))
(ha-leader "f n" '("find notes" . ha-search-notes))
#+end_src
I might replace my code with the [[https://github.com/benmaughan/spotlight.el][spotlight]] project, as it has a slick interface for selecting files:
#+begin_src emacs-lisp
(use-package spotlight
:config (ha-leader "f /" '("search files" . spotlight)))
#+end_src
