To cite a colleague of mine: I can read it, but I cannot understand
it. ;-)

Oh, indeed, I think I can confirm that after playing around with it.

Is there some special character acting as an AND, too?

For the time being, I've just mentioned that keywords should be comma
separated in the interactive spec of
`report-emacs-bug-query-existing-bugs'.

I guess that's the full text search Michael Albinus is talking about in

  http://debbugs.gnu.org/cgi/bugreport.cgi?bug=7449

I think these two possibilities have the disadvantage of matching
against the whole text, so searching for multi-tty will find all bug
reports, because multi-tty is a default feature and listed in the
Features list you get from `report-emacs-bug'.  Additionally, you cannot
restrict the search to open bugs.
