Orderless doesn't work as desired.

I haven't used Swiper or Ivy (the completion framework it depends on) recently, but at the time I wrote the Orderless documentation it used to be true that Ivy did not use completion-styles at all. I did write some separate Ivy integration instructions in the Orderless manual. That link just says to use this configuration:

(setq ivy-re-builders-alist '((t . orderless-ivy-re-builder)))
(add-to-list 'ivy-highlight-functions-alist '(orderless-ivy-re-builder . orderless-ivy-highlight))

Please let me know if that works.

Thank you for your comments. The following configuration does the trick:

(use-package orderless
  :ensure t
  :custom
  (completion-styles '(orderless basic))
  (completion-category-overrides '((file (styles basic partial-completion)))))
