I often look for information that could be either in some org-mode document, in an old email, or somewhere in the file system (and probably other places). Now I can use org-search, notmuch-search, and locate/find (in the shell) separately, but this is a little tedious as I need to modify the search to figure out the correct incantation. I was sure there was a way to combine searches, but Googling for it, I came up empty handed. Surely there is a solution?
