+I (David Bremner) use the following search (in my case as a saved
+search in emacs).
+
+ tag:notmuch::patch and not tag:notmuch::pushed and \
+ not tag:notmuch::obsolete and not tag:notmuch::wip \
+ and not tag:notmuch::moreinfo and not tag:notmuch::contrib
+
+You might or might not want as many exclusions. Another interesting
+search is
+
+ tag:notmuch::reviewed and not tag:notmuch::pushed
+
