I want to tag new patches, but not replay messages. I've tried to do it like this: notmuch tag +patch-new "tag:inbox and subject:'patch' \ and not subject:'re:'" but last rule (subject:'re:') seems to be ignored, as soon as i understand this happens because pattern 're:' is too short. Am i right? Are any other ways to accomplish this task? BTW: Is it possible to specify beginning(^) or the end in subject search pattern?
