Searching Collection on iPad?

OK, what am I doing wrong? I'm trying to search my Biblical Biographies collection for Barabbas, but I'm getting results in tons of resources that are not in that collection.  Here is the iPad screenshot along with a desktop screenshot of the collection and the expected results of the search (which works properly on the desktop):

Very weird...limiting searches to collections works for me on the iPad
