Hey, I'm playing around with the head of the git repository (bc64cdce289d84be2550c4fccb1f008d15eaeb0e) to try to figure out how the new folder: prefixes work, as folders are a critical part of how I organize my mail. (Since tags are not hierarchical, folders are the best way for me to group mail to a bunch of related addresses, while retaining the ability to separate out any mailboxes that become high traffic.) I'm using a pretty standard maildir++ layout. For example, underneath my database.path I have a bunch of mail in directories such as: .INBOX.Main/{new,cur} .mail.class/{new,cur} .mail.voicemail/{new,cur} It used to be the case that if I wanted to read all of my "mail" mail, I could search for folder:mail, while to look at just voicemail, I could say folder:mail.voicemail, etc. Now, I can't get anything to match a folder predicate period. For example, using notmuch as notmuch-0.17 and ./notmuch as notmuch-0.18-rc2+2~gbc64cdc, here's what I get: linux2$ notmuch count folder:mail 16257 linux3$ notmuch count folder:mail.class 1896 linux4$ notmuch count folder:mail.voicemail 34 linux5$ notmuch count folder:mail.voicemail/cur 34 linux6$ notmuch count folder:.mail.voicemail/cur 34 linux7$ ./notmuch count folder:mail 0 linux8$ ./notmuch count folder:.mail 0 linux9$ ./notmuch count folder:.mail.voicemail 0 linux10$ ./notmuch count folder:.mail.voicemail/cur 0 linux 11$ ./notmuch count path:.mail.voicemail 0 linux 12$ ./notmuch count path:.mail.voicemail/'**' 0 linux 13$ ./notmuch count path:.mail.voicemail/cur 0 linux 14$ ./notmuch count folder:mail.voicemail 0 What gives? Are the path and folder predicates completely broken, or is something very important missing from the new notmuch-search-terms manual page? How can I make this work? Thanks, David
