org-ql like search for org-roam. depends on the following packages not yet on melpa. sexp-string, delve, delve-show.

I wanted a better search engine for my org roam files. I was tired of fiddling with parenthesises to match tags only when using org-roam-find-file and didn't like that I couldn't make a boolean query.

The package is not on melpa yet. In the mean time you can try it out quickly with the following instructions and install it adding to load-path or manually by executing load-directory on a directory containing all the relevent files or through utilizing your emacs distributions prefered way of installing packages from github.

copy paste into a buffer and run eval-buffer on sexp-string code and org-roam-search code after removing the line (require delve-show) from org-roam-search code. delve-show is not critical for the operation of this package.

look through doom-emacs installation guide Add the following to ~/.doom.d/package.el.

(package! org-roam-search
  :recipe (:host github
          :repo "natask/org-roam-search"
          :branch "master"))

(package! sexp-string
  :recipe (:host github
          :repo "natask/sexp-string"
          :branch "master"))

(package!  delve
  :recipe (:host github
           :repo "publicimageltd/delve"
           :branch "main"
           :files ("*.el")))
(package!  delve-show
  :recipe (:host github
           :repo "natask/delve-show"
           :branch "master"
           :files ("*.el")))

and place the following in ~/.doom.d/config.el

(use-package org-roam-search
    :after (org-roam)
    ;:custom
    ;(org-roam-search-default-tags '("stub"))
    :bind (:map global-map
          (("C-c n f" . org-roam-search-node-find))
            :map org-mode-map
          (("C-c n i" . org-roam-search-node-insert)))
    )

and run ~/.emacs.d/bin/doom upgrade

run org-roam-search-node-find or org-roam-search-node-insert. They are drop in replacements for org-roam-node-find and org-roam-node-insert.

type in tag:tag1 search string. It is a valid search that displays nodes with tag tag1 and contain search string.

• ability to search for file by tag and by title distinctively.
• boolean matching, combining terms with either `and and `or. Defaults to combining terms with and.

for example, tag:query1,query2 `or title:query3 `and query4

searches for files that have tag query1 and query2 or have an alias/title matching query3, and also have either query4 as a title or a tag.

• integrate with delve-show to export org roam buffers into persistent form.

• tag
• title
• olp (path to node)
• context (olp plus tag)
• all (title and context)
• level (node level)
• destination (node that is pointed by link)
• source (node that points to link)
