[lug] grep question

A quick grep question:  I've got a file named "spam" that may contain
"hello", "goodbye", both or neither.

I need a grep command that returns true if either or both is present.
The grep man page suggests that you can use the infix operator |
(the pipe symbol) but I can't figure out the syntax.  Does anyone
know how?

I basically want something like:

grep 'hello!good' spam
