And this SearchWorks user feedback: https://jirasul.stanford.edu/jira/browse/SW-4346

Can we place a "0 results" page or text on Bento when all applications return 0 results. Example search from user: https://library.stanford.edu/all?q=Tratado+de+las+supersticiones+y+costumbres+gentilicias+que+hoy+viven+entre+los+indios+naturales+de+esta+Nueva+Espa%C3%B1a

Any work on adding text/page "0 results" should be coupled with work that might be done on the SearchWorks "0 results" page.
