Full Issue List

For Developers

Extensible search UI implementations

It is now possible to provide your custom search UI implementation that will become available in the list of search engines under Administration > Applications > Search.

To achieve this, we have declared the UI Extension point ID that accepts 3 parameters:

  1. title - the text to display for your implementation in the search engine select
  2. admin - a reference to the wiki page where you administrate your search implementation (ex: 'XWiki.SolrSearchAdmin')
  3. search - a reference to the search page that should be used when your search implementation is active (ex: 'Main.SolrSearch')

Deprecated and Retired projects

No project was retired.


No library was upgraded.


  • Renamed the lucene search module and modified the search-ui module. As part of the refactorings performed on the search application, the xwiki-platform-search-lucene module has now been renamed to xwiki-platform-search-lucene-api. Also, pages related to Lucene search that were previously inside xwiki-platform-search-ui have now been moved to the new xwiki-platform-search-lucene-ui module.

    If you were depending in your application on these modules/pages, please update your references accordingly. For more details on the new layout, lease see .

Backward Compatibility and Migration Notes

General Notes

You may also want to import the default wiki XAR in order to benefit from all the improvements listed above.

Always make sure you compare your xwiki.cfg and files with the newest version since some configuration parameters were added. Note that you should add so that XWiki will attempt to automatically migrate your current database to the new schema. Make sure you backup your Database before doing anything.

Issues specific to XWiki 4.5 RC 1

Existing custom search implementations

In case you were using a custom search implementation before this version which relied on previous naming and location conventions, you will need to make the necessary adjustments, meaning that you have to declare your implementation as an extension to the search application's extension point (see above).

API Breakages

The following APIs were modified since XWiki 4.4.1:

  •  New method to access bundle:
    org.xwiki.localization.LocalizationManager: Method 'public org.xwiki.localization.TranslationBundle getTranslationBundle(java.lang.String, java.lang.String)' has been added to an interface
  • Removed the workspaceName parameter to properly fix XWIKI-8394. The actual workspace name should be passed to the XWikiServer parameter instead:
    org.xwiki.workspace.WorkspaceManager: Parameter 1 of 'public com.xpn.xwiki.plugin.wikimanager.doc.XWikiServer createWorkspace(java.lang.String, com.xpn.xwiki.plugin.wikimanager.doc.XWikiServer)' has changed its type to com.xpn.xwiki.plugin.wikimanager.doc.XWikiServer
    org.xwiki.workspace.WorkspaceManager: Parameter 2 of 'public com.xpn.xwiki.plugin.wikimanager.doc.XWikiServer createWorkspace(java.lang.String, com.xpn.xwiki.plugin.wikimanager.doc.XWikiServer)' has changed its type to java.lang.String
    org.xwiki.workspace.WorkspaceManager: In method 'public com.xpn.xwiki.plugin.wikimanager.doc.XWikiServer createWorkspace(java.lang.String, com.xpn.xwiki.plugin.wikimanager.doc.XWikiServer, java.lang.String)' the number of arguments has changed)))
