Dear David, thank you for your kind persistence. I apologize for the
lack of clarity in my writing. Below is the full sequence of commands
(I just subsitute MYMSGID and MYMSGIDREPLY for two message IDs) as
well as my thought process.

$ notmuch search --output=threads "id:MYMSGID"
thread:000000000000a125
$ notmuch search --output=messages "thread:000000000000a125"
id:MYMSGID
$
# I know that MYMSGIDREPLY did respond to that message. I have it in
my mutt mailbox and it shows the down-right arrow signifying this. I
inspect the headers and there is indeed a header in MYMSGIDREPLY that
says "In-Reply-To: <MYMSGID>". I then do...
$ notmuch search --output=threads "id:MYMSGIDREPLY"
thread:000000000000c125
$ notmuch search --output=messages "thread:000000000000c125"
id:MYMSGIDREPLY
$

# What I expected (and did not get) was the following output:
$ notmuch search --output=threads "id:MYMSGID"
thread:000000000000a125
$ notmuch search --output=messages "thread:000000000000a125"
id:MYMSGID
id:MYMSGIDREPLY
$

# after regenerating the notmuch database, I did indeed get the output
that I expected.

Kind regards,

Xu
