Thread:Project:Support desk/How do I format search results / add section links to search results (the same way Wikipedia and other WikiMedia sites do)?/reply (3)

The "LocalSettings.php" for Wikimedia servers (I imagine, never seen them so don't really know) don't have a lot in them, and instead includes from other files. Most of the real settings are in InitialiseSettings.php with a little bit in CommonSettings.php, but the Lucene stuff is mostly in lucene.php.

Looking at the lucene code, there seems to be some stuff relating to search suggestions and related links that are only enabled if $wgLuceneSearchVersion is &ge; 2.1 (default is 2.0). (Presumably one has to do something on the backend to get these fancy features which is why the switch is there). But this is all just a guess.

p.s. All the secret passwords are here ;)
