如何对 org 文件夹按 tag 搜索

BobCromwell · 2020 年4 月 6 日 02:06

我知道可以用 org-agenda，但是有个问题是 org-agenda 会试图打开所有文件，300 个 org 文件就非常慢了或者报错了。不知道大家是怎么解决的。

用 org-agenda 报的什么错？

不用 org-agenda，可以考虑 grep-find.

“ 用 org-agenda 报的什么错？” 会报 too many files opend 。目前也是用 ag，grep 等实现类似的查询，不过感觉还是不那么方便。

我想的一个应用场景是可以支持 “tag=work distributed” 这样的的搜索，tag 部分可以支持 file tags 和 tag 的继承

;;; org-db.el --- An org database

;;; Commentary:
;; org-db is used to index org-files into a sqlite database to make searching
;; easier. It is complementary to things like `org-agenda-files'. I have found
;; that `org-agenda' is too slow to deal with large (thousands+) of org-files
;; that are spread all over your directories.
;;
;; It works with a `save-buffer-hook' that runs a function that adds an org-file
;; to a queue for indexing when you save it. The queue is processed whenever
;; Emacs is idle. This is done for performance reasons.
;; 1. org-db parses the org-file which can be slow for large files, and I don't want to wait while working.
;; 2. sqlite can only have one process working on it at a time, so async updates is not a good idea.
;;
;; org-db balances performance and accuracy in a way that works "well enough"
;; for me. There are a number of ways it can be out of sync and inaccurate
;; though. The main way is if files get changed outside of emacs, e.g. by git,
;; cloud drive sync programs, or other users in shared drives, files are moved
;; or renamed, etc. org-db doesn't have a good way to keep up with these kinds
;; of changes. You can use `M-x C-u org-db-refresh' to update all the files in

org-agenda 最基本功能就是用来处理这样的问题。

是，就是存在我说的那个 too many files opend 的问题

不存在这样一个单词 opend.
