Thanks Eli,

I actually was not aware of this command either. This seems like the
command I was originally looking for.
I guess this quite well covers my usecase (for which I wrote the info-occur
and adapted the info-apropos command).
Also, it seems to me this is fitting alternative/better/similar solution to
Augusto's suggestion...
