ReleaseNotesXWikiEnterprise24M1
First milestone of the XWiki Enterprise 2.4 version (Roadmap).
The highlights of this release are: Lucene by default and Lucene admin, rendering cache as well as performances and security improvements.
New and Noteworthy (since XWiki Enterprise 2.3.1)
Search
Changed default search engine
Lucene Search is promoted as default search.
The Lucene search has several benefits over the Database search:
- It indexes attachments (such as PDFs or MS Word documents) searchable. It does not replace the search page itself but rather makes more content available for searching.
- It provides a scoring for the search results.
- It offers pagination when there are lots of results.
- It scales well when there are lots of documents in the wiki.
- It supports multi wikis.
- It supports a strong query syntax.
New search configuration UI
The Search Application now has a dedicated section in the wiki administration section from which you can:
- Choose the default engine (Lucene or Database).
- See the status for the Lucene Search: the number of indexed elements and the number of elements waiting in the queue.
- Control the Lucene index by indexing the whole farm, indexing the wiki or customizing the index to your specific preferences.
For more information check out the documentation page.
Rendering cache
It's now possible to provide a list of pages for which to cache the result. See core.renderingcache.* properties to control it.
It's also possiblet to force a page to refresh by using refresh=1 parameter in the URL.
WYSIWYG improvements
Insert external image
You can now insert an external image in the edited page while in WYSIWYG mode. The external image is specified by its location on the web, i.e. its URL. To do this go to Image > Insert Image... menu and select the "External" tab:
New Code macro configuration
It's now possible to indicate which Pygments style to use with the default highlighter based on Pygments.

Backward Compatibility and Migration Notes
General Notes
You may also want to import the default wiki XAR in order to benefit from the improvements listed above.
Migration Notes
- the main entry point for search UI is now the Main.Search page that will use the configured search engine (Lucene by default), if you explicitly want to refer to Lucene or Database search you can Main.LuceneSearch and Main.DatabaseSearch pages. Note that nothing is broken here (Main.WebSearch page is still there and include Main.DatabaseSearch page), it's just the new clean way of targeting the search page.
