Yes. The restrict part will speed things up quite a bit, if you
want to restrict to functions.
Or, alternatively, you could use Namazu (which I use to generate
what RSiteSearch provides) to generate an index specific to your
own installed functions and packages. The trick is to cd to the
directory /usr/lib/R/library, or the equivalent, and then say
mknmz -q */html
which will pick up the html version of all the man pages
(assuming you have generated them, and I have no idea whether
this can be done on Windows). To update, say
mknmz --update=. -q */html
Then make a bookmark for the Namazu search page in your browser,
as a local file. (I haven't given all the details. You have to
install Namazu and follow the instructions.)
Or, if you have a web server, you could let Google do it for
you. But, I warn you, Google will fill up your web logs pretty
fast if you don't exclude it with robots.txt. I don't let it
search my R stuff.
I think that Macs and various Linux versions also have other
alternative built-in search capabilities, but I haven't tried
them. Beagle is the new Linux search tool, but I don't know what
it does.
