Extension:EzMwLucene

The extension EzMwLucene provides a simplified Lucene search to Mediawiki. It is designed to be easy to install, configure, and run. It provides real-time, multiple field indexing and searching as well as text indexing of standard attachment types (pdf, xls, doc, ppt, vsd). The server is a self contained Java application (no application server needed), and the client portion is a standard Mediawiki extension. It is currently in production on an internal site with over 1000 users running on Mediawiki 1.13.

Requirements

 * Java 1.6+
 * php_curl package

Installation
after EzMwLucene Installation Guide; See also the discussion page with quite a bit of trouble.

Setting up the server (Guide for Version 1.0)

 * 1) Extract the tarball
 * 2) Move the server directory to the directory of your choosing (here /srv/search/lucene/)
 * 3) Move the client/extensions/EzMwLucene directory  to your Mediawiki extensions directory
 * 4) Modify ezmwlucene.properties (in the server directory) as needed with your information, see below
 * 5)  If you're adding this to an existing wiki, you probably want to run the loader (see below) to preload documents (otherwise, they'll only be added to the index the next time they are updated)
 * 6) Modify service.sh if necessary for your environment
 * 7) Run service.sh start

Edit ezmwlucene.properties manually
Assure correspondence to LocalSettings.php lucene.index = /srv/search/lucene/index                         # location of the index server.port = 8080                                              # in $wgEzMwLuceneQueryUrl below mediawiki.name = Testwiki                                       # =$wgSitename mediawiki.databaseUrl = jdbc:mysql://localhost:3306/wikidb      # jdbc:mysql://$wgDBserver:DATABASEPORT/$wgDBname mediawiki.databaseUser = wikiUserName                           # =$wgDBuser mediawiki.databasePassword = WikiUserPassword                   # =$wgDBpassword mediawiki.imagesUrl = http://127.0.0.1/wiki/images/             # =URL/$wgScriptPath/images/ mediawiki.localImagesUrl = file:///srv/www/htdocs/wiki/images/  # =DOCROOT/$wgScriptPath/images/ (Having a proper install script would be nice). The mediawiki.database settings are only needed for the initial loader phase.
 * 1) mediawiki.databaseDriverClass = com.mysql.jdbc.Driver

Running loader.sh once in the set up phase
The loader script indexes the current set of documents, which is pulled directly from the wiki database. It assumes no database prefix (if $wgDBprefix is not empty, see work around in discussion page)

Changes to LocalSettings.php
(with the URLs modified as needed) 8080 = server.port entry in property file above
 * $wgEzMwLuceneQueryUrl: The URL of the Query service
 * $wgEzMwLuceneIndexUrl: The URL of the Index service

Comments
Pro: Cons: Open Questions
 * real-time indexing of text and attachments
 * The claim "designed to be easy to install" is not at all realized yet. See discussion page
 * unicode support missing
 * Does it support 1.15+ ? (I do have this working on 1.15.1 on Windows 2003 server, with the patch for wgDBprefix --Mark 12:12, 7 December 2009 (UTC) )
 * Does it support 1.14+ ?
 * how does is work with user right and access access extention?
 * "unicode support" urgently needed

Yes, I have it now working on 1.17 and intend to provide updates/patches soon. cmoman 20:31, 26 January 2012
 * Can we get the instructions posted now on getting it running on 1.17+? Thanks -MadX 09:31, 14 July 2013
