Profpatsch 84e9c7f104 feat(users/Profpatsch): add a example for omega search
Uses xapian under the hood to index the contents, then makes it
searchable with a CGI binary on http://localhost:8080

We could in theory index every -doc output this way to get local
documentation search for the current system (similar to `man-db`).
