We’ve noticed some weirdness with sorting item results when using the full-text search box in Advanced Search. This is happening for both the public and admin interfaces. In some searches that retrieve item records, sorting by the list of field options works as expected. At other times, it does not. I am wondering if some sort of relevancy sorting, or some other default sort, is overriding the sort-by-field options in these weird cases.
Here is an example on our live site: https://exhibits.library.umkc.edu/s/shining-a-light/item/search. If you search for “brouwer” in full-text search, the results sort as expected. If you search for “night” the results do not sort as expected. The same thing happens on the admin side as well.
