Not sure if everyone has seen John's latest post about indexing org files
with swish-e:
http://kitchingroup.cheme.cmu.edu/blog/2015/07/06/Indexing-headlines-in-org-files-with-swish-e-with-laser-sharp-results/
It's very impressive. It strikes me as a step towards an incredibly
ambitious project that would bring file indexing inside of Emacs -- so it
would not longer be necessary to go out to a shell or a Desktop Search tool
in order to find files that contain particular search terms. I'm looking
forward to your next steps, John!

Thanks Matt,
That is also my impression of where this will go. Eventually this will
move towards a database search engine, e.g. like Oleg's project at
https://github.com/wvxvw/sphinx-mode. I am not sure precisely which
direction though. Swish-e is nice, but at the moment you cannot
incrementally update the database, and full indexing is required every
time. I am not sure that is fixable, and swish-e does not do
unicode. There are half a dozen or so candidates to go forward on, and
they all have some pros and cons to think about.
It has a lot of other applications in org too, e.g. a file-system wide
agenda, tag search, etc...

Hi all,
I previously hooked up org with recoll with pretty good results. I’ve
written this up for worg, but I have my ssh key on a different
machine, so I can’t push now. Here is the info for the record.
** Recoll
In order to index using the [[http://www.lesbonscomptes.com/recoll/][recoll]] search engine, you will want to add
the following to your =~/.recoll/mimeinfo= file:
#+BEGIN_SRC
.org = text/x-org
.org_archive = text/x-org
#+END_SRC
You will also need a shell script to convert your org mode files to
HTML in batch mode. The script takes as an argument the file to
convert and prints the output to stdout. Here is an example:
#+BEGIN_SRC sh
#!/bin/sh
emacs --batch --eval "(progn (find-file \"$1\") (org-html-export-as-html) (set-buffer \"*Org HTML Export*\") (princ (buffer-string)))"
#+END_SRC
You will also need the following in your =~/.recoll/mimeconf=:
#+BEGIN_SRC
[index]
text/x-org = exec /home/egh/.recoll/rclorg ;
mimetype = text/html
#+END_SRC
Now, rebuild your recoll index. Org mode files should be converted to
HTML and indexed. It will take some time, because emacs will be
launched for each conversion. An alternative is to use [[http://pandoc.org][pandoc]] to do
the conversion. It can be configured as follows in your
=~/.recoll/mimeconf= file:
#+BEGIN_SRC
[index]
text/x-org = exec pandoc -s -f org -t html5 ;
mimetype = text/html
#+END_SRC
If you want, you might change the pandoc template or org mode output
to generate =meta= tags that will be recognized by recoll. See
http://www.lesbonscomptes.com/recoll/usermanual/RCL.PROGRAM.html#RCL.PROGRAM.FILTERS.HTML
for details.

Thanks for the link. I tried it, and it actually works great on my
system (unlike swish-e). And I did no configuration of mimeinfo, I only
told it to index my whole org/ directory.
If anyone is interested, I've added an Emacs interface to recallq (a
shell tool that comes with recoll that you have to build yourself). See
counsel-recoll command from
https://github.com/abo-abo/swiper/blob/master/counsel.el.
Initially, this command gives you a list of files that match the
query. After selecting the file, it's searched for the current query.
Unfortunately, the -A (abstract) switch isn't as useful as the context
that e.g. grep gives, so I went only with the file names.
regards,
Oleh

There is also a helm-recoll package available. I came across recoll a
few weeks ago when I saw that package! It also basically worked as
advertised and I am just looking forward to some free time to figure out
how to get the super focused search I worked out for swish-e.
Has anyone tried using emacsclient for the html export? Maybe that would
speed up indexing if a whole new emacs isn't spun up each time.

Of course! I’ve forgotten exactly what I was intending to accomplish
by converting to HTML - I believe I was generating citations - but
recoll should be able to index plain text without issue. This will
probably work better for org files, as well, since you can search the
complete content.

This is great, especially for me, as I’ve been using ivy lately.
I believe that you can rewrite using the recoll tool directly instead
of recollq, using `recoll -t -b 'search string'`:
(defun counsel-recoll-function (string &optional _pred &rest _unused)
"Grep in the current directory for STRING."
(if (< (length string) 3)
(counsel-more-chars 3)
(counsel--async-command
(format "recoll -t -b '%s'" string))
nil))
If you use `recoll -A -t 'search string'` and do some post processing
you could get snippets, too. I can’t see how to do that easily with
counsel--async-command, though.
best, Erik

Thanks, Erik. I've merged your pull request. So now it's very easy to
start using recoll with Emacs - outside of Emacs the only necessary
thing is:
sudo apt-get install recoll
And inside Emacs it's:
package-install counsel
I did look into the annotation switch. The thing is that it just shows
some database aggregates instead of the actual line context, like grep
does. With 30 candidates and no line context, a pure list of files looks
simpler than a list of files and a list of out-of-sequence words that
each file contains.

Hi Oleh
i start using counsel and the counsel-recoll and is quite good, thx for
this!
a small Q. when i launch the command am i supposed to see the search term
inline (like in grep) or just the file name it resides in. currently i just
see the filename that contains the search term. example screenshot:

You can't see the search term inline, only the file name. Recoll
doesn't support inline context. It has support for abstracts, but they
are disjointed, as in not a full sentence, but a summary of
keywords. Showing those is a possibility, but at times it's just too
much information.
For instance, here's one candidate for input 'git':
text/plain [file:///home/oleh/Dropbox/org/wiki/git.org] [git.org] 9921 bytes
ABSTRACT
title my git notes language en ... css articles done http git scm com
book en git branching branching workflows git branching workflows closed
2013 ... 22 00 done http git scm com book en distributed git distributed
workflows git distributed workflows closed 2013 ...
/ABSTRACT
I think the file name here is more relevant than the abstract, taking
into account that there are 59 other candidates, besides this one.
