This proposed extension (implemented by National Documentation Centre/EKT - http://www.ekt.gr) displays the advance search form after an advance search in DSpace. The current version of DSpace, returns a simple search form with the Lucene query that is not starange for the user. In case the user needs to redifine the query, he must change the Lucene query which is not wise at all. Given this extension, he can see the advance form filled with the initial search parameters and make hiw changes and search again.
Note: Make an advance search and notice that in the results page, the advance search form is displayed as well
