+[notmuch][] is a clean mail indexer. You know you got an email from
+someone with their current phone number, but can't remember where you
+put it? Notmuch to the rescue:
+
+ $ notmuch show from:jdoe@example.com home phone
+ message{ id:DF741236-…@example.com … filename:/home/you/mail/…

+[[Gentoo]] installation is simple:
+
+ $ emerge -av notmuch
+ $ notmuch setup
+ (interactive creation of ~/.notmuch-config)
+ $ notmuch new
+ (initial indexing)
+
+When you want to update the index, just run `notmuch new` again. You
+can get fancy with [[offlineimap]] hooks:
+
+ [Account Upsilon]
+ postsynchook = notmuch new
+
+but I just have a Bash alias in my [[dotfiles]] along the lines of
+
+ alias offlineimap-in='offlineimap && rm -f ~/mail/Junk/* && notmuch new'
+
+You can also get fancy with [mutt integration][mutt], but I just
+`grep` the search results on the command line to get what I want.
+
+P.S. I'm cleaning out my backlog of half-completed blog posts today,
+can you tell?
