The easiest way to answer this question is to try it. I did that, and
things didn't work as expected. I expected that once the message was
moved to a different folder, and 'notmuch new' was run, then the folder
search result would move with the message move. 

I tried to move a message from folder 'thinkpad' to folder 'Junk':

1. First I did a search that included the thinkpad folder, with a string
I know is in an email:

$ notmuch search folder:thinkpad 05K9519
thread:4ba02e2c665b09fb74dc6f1b6ea3aac2   2004-02-25 [1/1] J H. Maut; RE: [Thinkpad] thinkpad 600e LCD quesiton (thinkpad unread)

2. then I moved that email to my Junk folder and ran notmuch new:

$ mv INBOX.thinkpad/new1147465172.M760586P11592V0000000000000301I00141D45_7229.um\,S\=2421\:2\,S INBOX.Junk/new
$ notmuch new
Processed 1 file in almost no time.                    
No new mail. Detected 1 file rename.

3. then I tried to repeat the search I did in #1, searching for the
folder thinkpad and the string, and it still returns the result (this is
not expected! I would expect no result returned):

$ notmuch search folder:thinkpad 05K9519
thread:4ba02e2c665b09fb74dc6f1b6ea3aac2   2004-02-25 [1/1] J H. Maut; RE: [Thinkpad] thinkpad 600e LCD quesiton (thinkpad unread)

4. If i try and search for the same message in the Junk folder, I get no
results:

$ notmuch search folder:Junk 05K9519
$ 

5. If I do a show on the message, I see that notmuch knows that the
file is actually in the Junk folder:

$ notmuch show thread:4ba02e2c665b09fb74dc6f1b6ea3aac2

message{ id:BKEJKEHBAJJAFLAGIHJCGEEEECAA.J.H.Maut at somewhere.net depth:0 match:1 filename:/home/micah/Maildir/Personal/INBOX.Junk/new/1147465172.M760586P11592V0000000000000301I00141D45_7229.um,S=2421:2,S

Exactly the problem.
