Discovery Changelist

DSpace 6.0

The legacy search engine (based on Apache Lucene) and legacy Browse system (based on database tables) have been removed from DSpace 6.0 or above. Instead, DSpace now only uses Discovery for all Search/Browse capabilities.

DSpace 5.0

The new JSPUI-only tag cloud facet feature is disabled by default. In order to enable it, you will need to set up the corresponding processor that the PluginManager will load to actually perform the tag cloud query on the relevant pages. This is configured in the dspace.cfg configuration file using the following properties:

• Sidebar browse facets that can be configured to use contents from any metadata field
  
  • Dynamically generated timespans for dates
• Customizable "recent submissions" view on the repository homepage, collection and community pages
• Hit highlighting & search snippets

To clean up all these old "bi_*" tables, simply run:
