That would be handy, indeed, as well as in which package each function resides.
However, my own motive was that if you know the existence and exact name of
(seemingly) relevant functions, you can find the full syntax etc. throught R's
built-in help system. I'm not sure whether this would be simple, because "grep"
yields a variable number of hits, which must then be combined with a fixed
string value. I'll think about it.

search() gives a list of attached packages, so if you load all packages of your
interest you 'll get all relevant functions.

Certainly; for others it might be model, summary etc. Users can extend the
pattern list or load them from a text file, e.g.
patterns = read.csv(file.choose())

In my opinion it's better to CC the r-help, because someone in the vast R
community might come up with a faster, or better, solution.
