I search from my tree and I definately want to see it. Any further benefit in scrolling would be lost in my clicking back and forth to review. I will miss the more detailed view as I use it to constantly review and re-evaluate. Seeing two detailed items together can sometimes cause me to rethink a choice or sometimes an item to be compared didn't show up the first time I searched.
If you want to save space move stories to a separate heading for the search area than with books (when the search is narrowed). Also, use thumbnails for photos.
