Oh yeah, I guess normal regexps on the org files should be perfectly fine (duh). My first thought was going through org’s element API and whatnot, which is why I brought up performance. > This is from some proof-of-concept code for mu4e, where I have a > dedicated function to just scan the agenda files for a regular > expression tailored for `mu4e:msgid:' links, storing entries in a hash > table keyed to message-ids.

Notmuch has a search term for email threads and individual message IDs, so it’s why I brought it up: querying individual messages is just as easy as groups of messages. I don’t know mu4e so I don’t know what the equivalent to that would be over there, if any. -- Kind regards, Kristoffer
