Most of us already do this explicitly in our tagging scripts, so no harm in making it standard behaviour, I guess. Though to keep the implementation nice & clean, I'd advise against the use of parens: no need for escape chars, no messing with De Morgan's law, simply map the tag operations to their inverse in conjunctively joined filters: notmuch tag +A +B -- <filter> and not tag:A or not tag:B notmuch tag -C -D -- <filter> and tag:C or tag:D notmuch tag +A +B -C -D -- <filter> and not tag:A or not tag:B or tag:C or tag:D Peace -Pieter _______________________________________________ notmuch mailing list notmuch@notmuchmail.org http://notmuchmail.org/mailman/listinfo/notmuch
