Confirmed. In `org-agenda-filter-by-tag', ((or (eq char ?\s) (setq a (rassoc char alist)) (and tag (setq a (cons tag nil)))) (org-agenda-filter-show-all-tag) (setq tag (car a)) (setq org-agenda-tag-filter (cons (concat (if exclude "-" "+") tag) (if accumulate current nil))) (org-agenda-filter-apply org-agenda-tag-filter 'tag expand)) "\ <space>" will call (org-agenda-filter-make-matcher '("+") 'tag nil) ; => (and (or tags)) which matches entries with tags, not the entries without tags. But <space> is actually not documented, so I am not sure if it is a bug. I can see logic with <space> being "any tag" (it appears alongside other tag shortcuts), and I can see logic with <space> being "no tag" (consistent with `org-set-tags-command'). Changing the current behaviour will be a breaking change. I am inclined to change the current behaviour and document it, unless there are objections. -- Ihor Radchenko // yantar92, Org mode contributor, Learn more about Org mode at <https://orgmode.org/>.
