Any other complaints except the search capabilities (which I hope I
clarify below)?  I mean, ``info pages aren't so easy to use'' says
something much more general than just search, right?

First, `s' searches the entire manual, not only the current node.  If
it doesn't work for you, please tell the details: what you typed and
why you decided that it stops at the current node.

And second, using `i' is _precisely_ the right idea.  It's just that
you tried to search a wrong manual.  You should have tried looking
this in the ELisp manual, which is where Lisp programming issues are
documented.  I've just typed `i operating system RET' in the ELisp
manual, and immediately found myself on the very page that documents
the variables that one can use for OS-specific code.

Use the `i' command, of course ;-)
