Error when editing pages
I followed your tutorial and installed LuceneSearch. All went fine, but when I edit a page, I get this error:

Fatal error: Call to undefined method LuceneSearch::setLimitOffset in /path/to/wiki/includes/SearchEngine.php on line 222

I'm using Mediawiki 1.10.0. Is this a known problem or just a configuration issue? Looks like LuceneSearch.php or LuceneSearch_body.php don't define that function at all. Same with LuceneSearch::update function...


 * You're missing

$wgDisableSearchUpdate = true;
 * in your LocalSettings.php. It should be placed before the require_once statement. --Rainman 17:48, 12 July 2007 (UTC)

Installing Lucene on Windows 2003 Server
Is there a way to install the LuceneSearch under Windows? I Run my wiki on a Windows 2003 Server with XAMPP and I want to use the features of Lucene. I found at http://meta.wikimedia.org/wiki/Installing_lucene_search that wikipedia uses the C# engine of Lucene.

Is there a compiled version of the C# engine to install it on my Apache running on Windows 2003 Server?----stp-- 13:40, 1 August 2007 (UTC)


 * As far as I know, no. --Rainman 09:54, 3 August 2007 (UTC)

I am also interested in a Windows 2003 tutorial for improving MediaWiki search results. Cedarrapidsboy 14:29, 2 August 2007 (UTC)


 * You can use the old C# daemon following tutorial on Installing lucene search. Wikimedia sites used to use this one, but now use to the latest (java) version. The new version could in principle run on windows with some modifications (main problem is usage of symbolic and hard links), but there is no-one around the patch it. --Rainman 09:54, 3 August 2007 (UTC)

There is a .dll version available here: http://incubator.apache.org/lucene.net/download/, but I don't know if this helps
 * The problem is not in the lucene itself, but the LSearch daemon, that makes use of linux fs to efficiently fetch new indexes, keep old copies, and swap copies after a background warmup phrase. --Rainman 09:18, 28 August 2007 (UTC)

Missing Method?
I installed everything following the instructions (on MediaWiki 1.10.1), but I'm getting this when I hit the search-button:

Fatal error: Call to undefined method LuceneSearch::getRedirect in /var/www/mediawiki-1.10.1/includes/SpecialPage.php on line 396

Is this a known issue with 1.10.1, or am I missing something? --217.6.3.114 06:34, 6 August 2007 (UTC)


 * No idea, getRedirect is defined in SpecialPage, and LuceneSearch inherits SpecialPage. You might be using some odd php version, or something else might be wrong... --Rainman 10:55, 6 August 2007 (UTC)


 * My PHP- Version is (PHP 5.2.0-8+etch7 (cli) (built: Jul 2 2007 21:46:15)). Do you really think this might be a problem? I believe it is more likely that I forgot something obvious, not mentioned in the instructions. For example: I had to download ExtensionFunctions.php from svn, because it is not shipped with Mediawiki or the Extension. Do I need to register the Extension anywhere other than in LocalSettings.php? --217.6.3.114 12:55, 6 August 2007 (UTC)
 * I've seen people complain about various mediawiki stuff not working with php 5.2, switching back to php 5.1 usually fixes it. But I'm by no means php expert (I mainly do the java part), so I cannot really tell if it would help. If you can, give it a try, and let us know if it helps. --Rainman 16:48, 6 August 2007 (UTC)


 * There seems to be no php 5.1 package available for debian etch, so I guess there's no chance to make search work.--217.6.3.114 12:10, 7 August 2007 (UTC)
 * I submitted a bugreport: http://bugzilla.wikimedia.org/show_bug.cgi?id=10835
 * Yep, seen it .. I still think it might be a php problem, or maybe a broken eAccelerator or something like that... --Rainman 10:33, 21 August 2007 (UTC)
