Yep, it is a date, but the files it brought doesn't have that date
anywhere either :( . As a matter of fact, almost for any search term,
I always get some unrelated files.

Well, it doesn't tie up resources anymore (I can barely tell it is
running), but it took over a week for it to finish indexing, and, at
last, say that it was idle.  Consider I have over 200k files on my
home folder, so....

I use to use mlocate, and I'm happy with it, however, I got the
feeling this file indexer could be good, because you should quickly
get files that contains a string, without having actually read all
your files everytime you want to search (I don't believe mc have a
persistent index, does it?... I use to use find + grep, or locate +
grep (and a for) to search within file's content).
