Identical messages in multiple folders or email accounts

[Nicolas Bock]

Hi,

In the case of identical messages in multiple folders, is it possible
to tag a specific copy? All my attempts to limit `notmuch tag` and
`notmuch search` to a particular folder have failed so far.

    $ notmuch tag +test-tag
id:218107fa-7705-67a9-a5f5-580260a9405f at nwra.com and
folder:acct_2/Archives/2019
    $ notmuch search --output=files tag:test-tag and folder:acct_2/Archives/2019
    /home/nbock/Mail/acct_1/[Gmail]/Trash/cur/887174bc-2da7-11ea-ba39-28f10e4fd9ec,U=14852:2,S
    /home/nbock/Mail/acct_2/Archives/2019/cur/1577989597.767223_920.rubberducky,U=15165:2,S

Best,

Nick
