When I use Emacs on a Linux OS, I search through files with
rgrep. On Windows machine this takes some additional setup. Is there an Emacs-powered solution for searching through multiple files that does not depend on external utilities?
ernie is a 100% Emacs Lisp script that can be used as a drop-in replacement for grep making it easy to grep using the native version of Emacs on Windows
I have not tried it, but there you go.
