> It would be nice to have a FilterFunc that allows to filter based on a tuple
> in the stream being part of either another tuple of a bag.
> Data (e.g. session data joined with e.g. follow-up sessions where)
> > BAG: {('/login'), ('/show'), ('/logout?user_id=2000')}, TUPLE:
> > ('/logout?user_id=2000')
> > BAG: {('/home'), ('/about')}, TUPLE: ('/admin')
> > BAG: {('login')}, TUPLE: ('/logout')
> It would be great to be able to filter filter based on criteria <B1 CONTAINS
> T1> or <T1 CONTAINS T2>. In the above case, the only result of such an
> operation would be the first entry '/logout?user_id=2000' - it should be
> obvious that this is useful.
