+Wouldn't this problem be solved by each filter appending a bracketed\r
+version of your filter?\r
+\r
+You start with tag:inbox and you filter on "term1 or term2" you'd get:\r
+\r
+        tag:inbox and (term1 or term2)\r
+\r
+Doing it again would result in...\r
+\r
+        tag:inbox and (term1 or term2) and (term3 or term4)\r
+\r
+To me, it would seem the most intuitive solution.\r
+\r
+Actually, I think I'll add that to notmuch.vim right now. :)\r
