Let us assume LibraryA and LibraryB each have a copy of Book1 and Book2. LibraryA's copy of Book1 has an acquisition date of 2001, and their copy of Book2 has an acquisition date of 2010. LibraryB's copy of Book1 has an acquisition date of 2013, and their copy of Book2 has an aquisition date of 2006. If we do an advanced search which a branch limit for LibraryA, and sorted by "Acquisition date: newest to oldest", we would expect the results to be ordered: 1. Book2 2. Book1 However, what we actually get is: 1. Book1 2. Book2 This is because the search is sorting by *all* the acquisition dates, not just the acquisition dates of LibraryA's holdings.
