Some CO/KL/DL awards pop up on nwa.com, but for other partner awards you'll need to call Worldperks. HP can't help you, since they don't have access to your WP account.
But from
http://www.nwa.com/freqfly/earn/airfl.shtml it looks like HP award tix are limited to HP flights "between the United States and Mexico/Canada/Alaska as well as Northwest coded flights [on HP metal] between Phoenix/Las Vegas and Los Angeles/San Francisco when connecting to Northwest Airlines flights to/from Asia."
So you might be able to score the YVR award (assuming you're originating in the US and there is availability). But IND sounds unlikely. IND's usually pretty cheap anyway, though, so why not just buy the ticket?
P.S. Be careful when using the term "direct." "Direct" in airline parlance does not mean nonstop, but means "one 'flight number' with as many stops and equipment changes as the airline cares to include." "Nonstop" means nonstop. Not trying to be sassy, just helpful (hopefully my tone isn't misconstrued).
