How can I use the find_theorems mechanism to search the whole Archive of Formal Proofs (AFP)?
I have downloaded the archive to my machine, and I am able to import theories from it. For instance, if I write imports Kleene_Algebra.Kleene_Algebra_Models then all the theorems in that theory are successfully made available to me. But if I then type find_theorems <expression>, I only get search results from the specific theory I imported. What if I want to search the whole archive? For instance, perhaps somebody has proved a theorem that is useful to me, but I don't know what they called their theory.
