What is this about?
According to Uncle Ezra, in March 2006 Cornell replaced the Inktomi search engine it had been using for University website searching with a Google Search Appliance. The Google Search Appliance (GSA) is administered by the Office of Web Communications. The GSA now supports the search you see on the Cornell Identity Banner on most Cornell University web pages.
The Office of Web Communications has provided instructions for modifying the Identity Banner search dialog to limit results to a single domain. This is the Unit Search capability. This could work for searching domains ending in 'library.cornell.edu', but many of the Cornell Universiy Library digital collections have different domain names. (This search of domains ending in 'library.cornell.edu' seems to be what the 'Search Library Pages' link on the Library Gateway pages is doing.)
