Thank you for the suggestion. I have found this function and use it in
my own code. My question is: how do I search for duplicates from within
emacs? I looked at the info, and it only mentions displaying duplicates
when they are found, but not finding them. I can get a list of message
ids that correspond to duplicates using the command line, but I do not
know how to display them in emacs.

Maybe an alternative could be to run `notmuch tag' on the output of
`notmuch search --duplicate=2 --output=messages '*'' to first tag the
duplicates. Something like this:

notmuch search --duplicate=2 --output=messages '*' | xargs -I % notmuch tag +dup %

then I could search for the dup tag…

Do I have to use this workaround or is there a more direct way?

Thanks again,

Alan
