Access to Memory (AtoM)

To reproduce:
- Create a new term in the subjects taxonomy, with the "Use for" field set
- Go to browse > subjects, and in the search box there search for the value entered in the "Use for" field above
Results should return the desired subject term

- Now click the search bar at the top left of AtoM and click "Advanced search"
- In the advanced search page, set one of the fields to "Subject access points" and search for the same "Use for" value as before

Result:
- No results are returned

Expected result:
- The search results should be consistent between the basic subject terms search and the advanced search. Or if not, it should be clarified to the user what the differences between these two searches are and why a UF term isn't searchable in the advanced search page.
