for me coming from planner and muse it is useful to search in my old
repositories too. Assuming everything is under ~/org I can easygoing search: 

(defun mpe-org-grep (string)
  "Grep wrapper for searches in org hierarchy"
  (interactive "sOrg Search (regexp): ")
  (let ((grep-find-command "find ~/org/ -type f -print0 | xargs -0 -e grep -nHi
-e "))
      (grep (concat grep-find-command string))))
