  Tried this the other day but couldn't figure out how to use it. Is it invoked from eshell, dired, a pdftool buffer, or what?

    Make sure to turn on pdfgrep-mode (a global minor mode, its role is to advise compilation-mode to make it deal with pdfgrep output) and then run M-x pdfgrep with a syntax similar to M-x grep, so you need to specify the filename(s) to grep in. A full arg list after M-x pdfgrep will be something like: pdfgrep -H -n -i points rulebooks/Tzolkin*pdf You don't need to be in a pdf buffer to invoke it. Here is what I have in my .emacs: (use-package pdfgrep :config (pdfgrep-mode))

  This looks really neat. I wish I had known about it in gradschool. I used helm-bibtex to manage my bibliography (which is awesome, and about 10x better than mendelay). If you combined pdfgrep with the semantic information helm-bibtex already has, that would be super powerful.
