Thanks for hinting me to that solution and the worg-site. After having worked with regexp-searches for a day, I see that I can do what I want. Anyway it's quite an amount of typing. For some reasons I noticed a strange bug (?) connected to regexp-searches. Whenever I do a org-tags-view, some of my org-files get the double asterisk in the status-bar. They haven't changed but Emacs tells me that they had. This always happens to the same three files, other org-files are untouched. Does anybody else have that phenomenon? Greetings, Sven
