Search
From MediaWiki.org
MediaWiki's full-text search is split between back-end and front-end classes, allowing for the backend to be extended with plugins.

[edit] Work for MediaWiki 1.13
Some work is going on now (March 2008) to improve the front-end for MediaWiki 1.13.
- Thumbnails
- done Hits that return 'Image:' pages now include a thumbnail and basic image metadata instead of raw text extracts.
- Thumbnails for media gallery pages and categories might be great!
- Text extracts
- These need to be prettified... a lot :)
- Categories and other metadata?
- Be nice to add some stuff while keeping it clean
- Search refinement field
- Recommend moving this up to the top, like the limited one LuceneSearch extension had.
- The namespace checklist is currently awful, should be cleaned up in some nice way.
- ??
[edit] Back end
MediaWiki currently ships with two functional search backends; one for MySQL 4.x and later, and the other for PostgreSQL. Custom classes can also be loaded, and $wgSearchType set to the desired class name.
[edit] SearchEngine
This is an abstract base class, with stubs for full-text searches in the title and text fields, and a standard implementation for doing exact-title matches.
[edit] SearchMySQL4
The SearchMySQL and SearchMySQL4 classes implement boolean full-text searches using MySQL's fulltext indexing for MyISAM tables. (In old versions of MediaWiki there was a SearchMySQL3 class as well, which did some extra work to do boolean queries.)

[edit] SearchPostgres
I'm not actually sure how SearchPostgres and SearchTsearch2 classes relate. Is one of them obsolete, or... ?
[edit] Extensions
[edit] MWSearch
The MWSearch extension provides a SearchEngine subclass which contacts Wikimedia's Lucene-based search server. This replaces the older LuceneSearch extension which reimplemented the entire Special:Search page.
