	<p>In a slightly more complex example 2 below, we are looking for all projects that
	are associated with two other projects (each is specified by name). We use the
	same technique with <b>QQ::Alias()</b> as in example 1, except that we now
	mix it in with relationships expanded to other tables.</p>
