Org-mode and searching for multiple occurances

Org-mode and searching for multiple occurances

[-- Attachment #1.1: Type: text/plain, Size: 864 bytes --]


Hello to everyone!

I am a teacher trying to teach young people how to use org-mode for writing. We have created a database with notes on literature review outlined in org-mode in the following format:

* jones2000
blah blah blah keyword1 keyword2
*jones2007
blah blah keyword2

and so on. I was wondering whether there is a way where one can search for a keyword in the database (more than 350 papers up to now) and can get in an automatic fashion in which of the jones' entries these keywords occur (pretty much like using MS Access and running a query). Is this possible? Maybe what I am asking for is outright crazy/impossible but I thought I should give it a go!

Hello Evita,

you may want to try M-x org-occur:

> org-occur is an interactive compiled Lisp function in `org.el'.
> 
> (org-occur regexp &optional keep-previous callback)
> 
> Make a compact tree which shows all matches of regexp.
> The tree will show the lines where the regexp matches, and all higher
> headlines above the match.  It will also show the heading after the match,
> to make sure editing the matching entry is easy.
> If keep-previous is non-nil, highlighting and exposing done by a previous
> call to `org-occur' will be kept, to allow stacking of calls to this
> command.
> If callback is non-nil, it is a function which is called to confirm
> that the match should indeed be shown.

But this only shows the matching entries, it doesn't generate a list of the 
entries (like running a query on a database).

Hth,
	Stephan

You can use org-search-view (C-c a s).

Best,
Matt

Just a remark:
If the file is not in org-agenda-files it is "C-c a < s"

well I don't think that using *Agenda* is what Evita is looking for, 
or at least I was not able to obtain a satisfactory view
of the authors with keyword2 occurrence in my test.org file.

I think that your first solution:  

M-x org-occur

is the best *org-option* 
(Isn't better using bibtex and bibtex tools?)

cheers,
Giovanni

I'm not sure I follow you here. The function org-search-view (C-c a s)
searches all org-agenda files for a regexp and/or word (or as Stephan
pointed out searches the current file with a restriction) and returns a
list of entry headings that contains that keyword. AFAICT, this is the
behavior the OP was looking for:

--8<---------------cut here---------------start------------->8---
Search words: keyword2
Press `[', `]' to add/sub word, `{', `}' to add/sub regexp, `C-u r' to edit
  test:       jones2000
  test:       jones2007
--8<---------------cut here---------------end--------------->8---

One more consideration: If the OP wants genuine tag functionality,
perhaps it would be better to add the keywords as tags. E.g.,

--8<---------------cut here---------------start------------->8---
** jones2000						  :keyword1:keyword2:
blah blah
** jones2007							   :keyword2:
blah blah
--8<---------------cut here---------------end--------------->8---

Best,
Matt
