+\r
+So, "notmuch show <search-terms>" is clear enough---it works as it does\r
+today.\r
+\r
+The new command, ("notmuch search --output=3Dmessages"), would be quite\r
+different. It would have single-line output for each message, (as\r
+"notmuch search" has single line-output already, but for threads by\r
+default). You can see behavior like this in the "notmuch\r
+search-messages" command for which I sent a patch a while ago, (but have\r
+never merged).\r
+\r
+The idea is that "notmuch search" would always give single-line output\r
+suitable for various kinds of processing.\r
+\r
+For example. How much mail have I sent?\r
+\r
+ notmuch search --output=3Dmessages tag:sent | wc -l\r
+\r
+That's something you can't do with a thread-based search, (and it's not\r
+convenient to get a robust result from "notmuch show").\r
+\r
+Once this is combined with a new --format to select what gets printed, I\r
+can imagine a lot of useful things, like collecting email addresses:\r
+\r
+ notmuch search --output=3Dmessages --format=3D"${FROM}" to:cworth@cworth.o=\r
+rg\r
+\r
+or whatever. I can imagine a lot of different queries I'd like to be\r
+able to make of my mail store with things like this.\r
