This is one of the purpose of my R search page.  I have all
packages installed.  You can also search the help list, etc., in
the same search.  Some people have bookmarks for it.  Of course
you need to be connected to the internet.

I think that any attempt to replicate this for a single user, or
even the packages, would be difficult.

BUT, it might help to install just the help pages for all
packages, without the packages themselves.  Then help.search()
would find things.  (I have no interest in figuring out how to do
this, but maybe someone else does.)
