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.
