Is that true? That does limit the usefulness of ? as it implies that
you must already know the function that you need.

But that's just a problem with the current implementation. Better
indexing could make full text search of all documentation practical
instantaneous. This is one argument for a centralised documentation
web site - such indices are much easier to set up in a modern web
development environment. I could imagine this being an eventual
feature of crantastic.org, but it requires on some tool to turn Rd
files into a form more easily parsed with off-the-shelf tools (ideally
xml).
