Search -- did I do it wrong?

I recently discovered that two programs I watched and thought were canceled will in fact be returning. (I have a Roamio Plus with the latest software.) I searched for "Extant" and found it, then created a new OnePass for All Channels. I tried searching for "Unforgettable" (it'll be coming back to A&E instead of CBS where I previously watched it) and it's not there. I get two movies by that name and a handful of other things with that term in description or episode titles, but not the actual series as I did with Extant and have previously done with some other shows when I heard about them.

Have I missed a trick? Or is the search simply getting bad info in my results?
