Search for tagless headings in org files

Hi - how can you search for tagless headings (headings without any tags added) in org files? All the search options/functions I can find allow filtering or selection by specific tags, but I can't find a :no-tag or similar to use as argument (my org roam daily workflow involves tagging headlines by topic, sometimes i miss the tag on capturing the note, so want to go back and file all notes (headings within files) that don't have tags) thank you!

if you can write some emacs-lisp you can write two queries using org-ql: \- one for all headings \- one for headings without tags and compute the difference.

Define a filter function (defun my/org-roam-node-filter-no-tags (node) (null (org-roam-node-tags node))) Define a custom command to find existing nodes without capturing (defun my/org-roam-node-find-no-tags () (interactive) (org-roam-node-visit (org-roam-node-read nil #'my/org-roam-node-filter-no-tags nil t))) Or wrap `org-roam-node-find` command to also allow capturing new nodes (defun my/org-roam-node-find-no-tags () (interactive) (org-roam-node-find nil nil #'my/org-roam-node-filter-no-tags))

>(defun my/org-roam-node-filter-no-tags (node) (null (org-roam-node-tags node))) > >Define a custom command to find existing nodes without capturing > >(defun my/org-roam-node-find-no-tags () (interactive) (org-roam-node-visit (org-roam-node-read nil #'my/org-roam-node-filter-no-tags nil t))) > >Or wrap org-roam-node-find command to also allow capturing new nodes > >(defun my/org-roam-node-find-no-tags () (interactive) (org-roam-node-find nil nil #'my/org-roam-node-filter-no-tags)) thank you! appreciate it - though I think this is picking up the nodes and not the individual headlines within each node - i manage org roam dailies with a node ID for each day, but then have multiple headlines under each node. those headlines are tagged with the topics (or are left tagless - and it's those I'm trying to find) and it would be ok to have results buffer listing the files in which there are tagless headings

> multiple headlines under each node. Oh, I see. I would probably use `org-ql` here. Use an `org-agenda`-like UI (defun my/org-roam-dailies-find-no-tags () (interactive) (org-ql-search #'org-roam-dailies--list-files '(not (or (property "ID") (property "TAGS"))))) Use a `completing-read` UI (defun my/org-roam-dailies-find-no-tags () (interactive) (org-ql-find (org-roam-dailies--list-files) :query-prefix "!property:ID !property:TAGS"))

>(defun my/org-roam-dailies-find-no-tags () Alright! Thank you very much. Got this working. Revised to the below, found that needed to exclude the parent folder name from the list of files and `directory-files-no-dot-files-regexp` made it work. Below is final code: (defun ql-org-roam-dailies-find-no-tags () (interactive) (org-ql-search (directory-files "~/OrgFiles/OrgRoam/daily" nil directory-files-no-dot-files-regexp) '(not (or (property "ID") (property "TAGS"))))) Generates a list of the headings in files that have no explicit tags. Headlines with inherited tags but no explicit tags are still listed, but that's no problem as I need to clean up those errant `FILETAGS` entries anyway. Only thing I've found: I have my entire Org file structure in a git repo and projectile picks it up as a project. The function above *only* works properly if I have an actual file in the `.../daily` folder open. Not a problem for me to do that, but not sure why it's required. Now playing with :super-groups to get more helpful results formatting.

>The function above only works properly if I have an actual file in the `.../daily` folder open. You use file names relative to "~/OrgFiles/OrgRoam/daily". Try `(directory-files "~/OrgFiles/OrgRoam/daily" t directory-files-no-dot-files-regexp)`.

>Try > >(directory-files "\~/OrgFiles/OrgRoam/daily" t directory-files-no-dot-files-regexp) > >. Bingo. That fixed it. Got another function working to filter by user input tag as well: (defun my-read-tag-with-completion () (interactive) (completing-read "Enter a tag: " (org-get-buffer-tags))) (defun ql-org-roam-dailies-find-by-user-tag () (interactive) (set 'user-tag (my-read-tag-with-completion)) (org-ql-search (directory-files "~/OrgFiles/OrgRoam/daily" t directory-files-no-dot-files-regexp) '(tags user-tag) :super-groups '((:auto-category t)))) Thanks for all the help! This has been on my to-do list for months, and now means I can clean up all the prior files. EDIT: actually, the above function works only first time around, there's some issue with persistence in the results buffer even if killed after first execution. Solve another time.
