When performing a search using Ultranet's Search Bar, results are returned for not just your Ultranet site but also from external repositories via Digital NZ. In Ultranet 2.3.3, we introduced search results for edna (Education Network Australia).
However, after a recent review in Australia, edna has been marked for decommissioning (commencing 30 June 2011). As a consequence, the Ultranet plug-in introduced to return results from the Australian repositories is no longer operable.
We will remove the 'edna' search results tab from the final release version of Ultranet 2.3.4.
For more information about edna's decommissioning, please read their notice page: http://www.edna.edu.au/edna/go/ednaclosure. The edna site will be available until 30 September 2011.
