+\r
+You might expect to be able to find all archived messages with:\r
+\r
+       notmuch search not tag:inbox\r
+\r
+(And if I had written the query parser that would work fine.)\r
+\r
+But oddly, that fails because in Xapian's query parser the NOT operator\r
+is not a unary operator but is instead a binary operator of AND_NOT.\r
+\r
+I think the lack of a unary not is a bug in Xapian. In the meantime,\r
+what we could use here is some syntax for a query that is guaranteed to\r
+match all messages. Anyone have any ideas?\r
+\r
+Meanwhile, if it's not that you're trying to list all archived messages,\r
+(which I think would be a rare thing to want), but instead you want all\r
+archived messages matching <some-term> then you can simply do:\r
+\r
+       notmuch search <some-term> and not tag:inbox\r
+\r
+I hope that helps.\r
+\r
+Happy hacking,\r
