I did 3 Smart searches in Books, in a row. I went back-arrow to the second search, and the results where there. I went back again to the first search, results also there. I went forward one result, results were there. But when I went forward again one more time to the latest search, the search query itself re-populated the box, but results were still from the prior search. I had to re-query to get the latest search results again.
