The MWSearch extension is a MediaWiki backend to fetch search results from MediaWiki Lucene-based search engine.

 Note: Used by Wikimedia Foundation until 2014, but to be replaced by Extension:CirrusSearch.

Installation

If you haven't already, install the Extension:Lucene-search extension first. That is the search backend that this extension uses, it is required.

• Download and extract the files in a directory called MWSearch in your extensions/ folder. If you're a developer and this extension is in a Git repository, then instead you should clone the repository.
• Add the following code at the bottom of your LocalSettings.php:

require_once( "$IP/extensions/MWSearch/MWSearch.php" );
$wgSearchType = 'LuceneSearch';
$wgLuceneHost = '192.168.0.1'; // IP address of the server
$wgLucenePort = 8123;
$wgLuceneSearchVersion = 2.1; // comment this out if you are using the old version 2.0

• Install the search engine
• Done! Navigate to "Special:Version" on your wiki to verify that the extension is successfully installed.

To load-balance with from multiple servers:

$wgLuceneHost = array( "192.168.0.1", "192.168.0.2" );

If used on a Gentoo based server make sure dev-lang/php was emerged with the curl USE flag set, otherwise search attempts will fail because nothing will be sent to the lsearchd.

Installing the search engine

Lucene-search daemon needs to be running on the specified host(s). For instructions see Extension:Lucene-search.
