I would guess because he's new to R.

The first place to start such a search is in R itself.  Try

??"topic"

and you might find something.  (This doesn't work for me for the topic 
"X-12 ARIMA".)

You can also just use Google.  Lots of people think that putting the 
letter R into a Google search is hopeless, but in fact several of the 
top 10 hits I get with the search "R X-12 ARIMA" look relevant.

Finally, there's the built in RSiteSearch function, and the sos package 
that puts a nice front-end on it.
