Does secondary filtering allow multiple tags?

Does secondary filtering allow multiple tags?

[Hsiu-Khuern Tang]

Hi all,

Suppose I have tagged some of my TODO headings.  In an agenda view, is it
currently possible to filter (using org-agenda-filter-by-tag) all entries that
are tagged with (say) either "project1" _or_ "project2"?  One can certainly do
"project1" _and_ "project2" by narrowing the filter.

I am trying to look at my weekly agenda, restricted to two particular projects
that are identified using tags.

I tried defining a custom agenda view with a org-agenda-skip-function defined
to match ":project1:" or ":project2:", but this doesn't work with inherited
tags.

Here's a workaround.  I use org-map-entries to select all headlines directly
tagged with "project1" or "project2" and tag them with something unique, say
"CUR".  Then I can use the ordinary filter mechanism in an agenda view to
restrict to headlines tagged with "CUR".

,----
| (setq cur_tags '("project1" "project2"))
| 
| ;; Unbind the variable
| ;; (makunbound 'cur_tags)
| 
| (setq match_string (concat "+TAGS={" (mapconcat (lambda (x) x)
| 						cur_tags "\|") "}"))
| 
| ;; Remove the "CUR" tag:
| (org-map-entries '(org-toggle-tag "CUR") "CUR" 'agenda)
| 
| ;; Turn on the CUR tag for all headlines (directly) tagged with
| ;; any member of cur_tags
| (org-map-entries '(org-toggle-tag "CUR" 'on) match_string 'agenda)
| 
| ;; Count the number of headlines (directly) tagged with any member of
| ;; cur_tags:
| (length (org-map-entries t match_string 'agenda))
`----

Maybe someone will find this useful, or think of a more elegant solution.

Correction: the above should have an extra "\":

,----
| (setq match_string (concat "+TAGS={" (mapconcat (lambda (x) x)
| 						cur_tags "\\|") "}"))

Hi Hsiu,

nice hack.  But I am still wondering why you do not
use "primary filtering" for this, i.e. a tags search
for "project1|project2"

     C-c a m project1|project2 RET

I couldn't get such a search to work with a daily/weekly/monthly agenda view.
I was trying to restrict the weekly (say) agenda view to just two projects
(identified by tags), which seems like a nice view for scheduling tasks.  I
would love a simple way to do this.  If different projects were in different
files, then one can modify org-agenda-files temporarily to achieve this, but my
projects are not always cleanly separated that way.

Yes, you are right, for the agenda this cannot be achieved,
except for constructing your own org-agenda-skip-function.
