Find stuff in org-mode anywhere

I write scientific papers, keep notes on meetings, write letters of recommendation, notes on scientific articles, keep TODO lists in projects, help files for software, write lecture notes, students send me homework solutions in it, it is a contact database, … Some files are on Dropbox, Google Drive, Box, some in git repos, etc. The problem is that leads to org-files everywhere on my hard drive. At this point I have several thousand org-files that span about five years of work. It is not that easy after a while to find them. Yes there are things like recent-files, bookmarks, counsel-find-file, helm-for-files, counsel/helm-locate, helm/counsel-grep/ag/pt, projectile for searching within a project, a slew of tools to search open buffers, there is recoll, etc… There are desktop search tools, and of course, good organization habits.
