Comment 5 for bug 1790231

Thanks for this patch and the testing all, however this doesn't seem to be working as expected after rebasing to current master.

Genres work as expected, however with the initial example of record 78, clicking on "Concerto (Horn)" filters the list down to 2 items: Horn Concertos and Huntington Student Recital(noted to not have that subject heading). None of the subject headings under record 207 appear to work, as well. My best guess is that some change has been made to the API that will need to be addressed, though I'm not sure what that change would have been.
