+\r
+This was definitely a design choice (I think probably by Austin/jrollins) and I\r
+think it makes sense: why would you want to include one include spam\r
+messages when you are searching for deleted messages?\r
+\r
+A change would break my setup - not in itself a problem as I setup this\r
+way to make sure I exercised the exclude code. I tag all my notmuch\r
+mailing list mail tag:notmuch and have that as an excluded tag. Then\r
+mailing list results do not clutter up results when I am doing personal\r
+searches.\r
+\r

+\r
+I don't think anyone has touched this code for over two years: git blame\r
+seems to suggest March 2012.\r
+\r

+\r
+I do think it would be nice to have a clear way of turning excludes off\r
+in the emacs frontend. Without a query parser it's not clear what the\r
+best way to do it is: I suggested a hack which allowed --exclude=false\r
+to be passed as part of the search. We could add a toggle to rerun a\r
+search with exclude=false but that doesn't help much for saved searches\r
+or manually entered searches.\r
+\r
+Best wishes\r
