Bug 28518: Display missing inputs for "Return to the last advanced search"

When more than 3 search terms are passed on the advanced search form,
the "Return to the last advanced search" feature does not display them.

Test plan:
Perform an adv search at the OPAC, enter more than 3 terms, launch the
search, click the "Return to the last advanced search" link and confirm
that all the entries are there.
