First, read Mark's reply about database upgrade, and heed the notice about upgrade being automatic but downgrade requiring a reindex of all your mails. Here's additional commentary on the specific queries. > linux7$ ./notmuch count folder:mail > 0 > linux8$ ./notmuch count folder:.mail > 0 These two will not match anything. > linux9$ ./notmuch count folder:.mail.voicemail > 0 After the upgrade, this should work for .mail.voicemail/{new,cur}. > linux10$ ./notmuch count folder:.mail.voicemail/cur > 0 This won't match anything. To specifically search for messages in cur, you can use the new path prefix, path:.mail.voicemail/cur > linux 11$ ./notmuch count path:.mail.voicemail > 0 This will match messages in .mail.voicemail only, and nothing in the cur or new subdirectories. > linux 12$ ./notmuch count path:.mail.voicemail/'**' > 0 I'm not sure your quoting will work, but if you don't have any other subfolders than cur and new, this should be equal to folder:.mail.voicemail > linux 13$ ./notmuch count path:.mail.voicemail/cur > 0 This should match messages in the cur subdirectory. > linux 14$ ./notmuch count folder:mail.voicemail > 0 This won't match anything.
