Compiling to create lucenesearch.jar failed[edit]
I am trying to install the lucene engine for our wiki but the compile of lucene fails.
Ant gives back a lot of error messages during the compilation, errors like:
[javac] /root/lucene/lucene-search/org/wikimedia/lsearch/SearchState.java:331: cannot find symbol

Can you help me to solve these error messages or provide a binary?
Many thanks in advance. --Phaidros 12 January 2008
- Are you compiling with a Sun Java 1.5+ compiler? If so, can you provide the beginning of the error log? --Rainman 00:55, 13 January 2008 (UTC)
Yes, I am using the opensuse 10.3 distribution and javac 1.5.0_13. I hope that the error messages I provide below are enough, sorry for my low experience in java build processes.
I´ll provide the first part and the last messages here:

Cannot bind RMIMessenger exception: non-JRMP server at remote endpoint[edit]
Hello everyone,
I'm quite new in Lucene stuff and I have a problem. I can't get Lucene Java working on one of my server. I've setup it on another server for Mediawiki and it works fine.
It's a GNU/Linux Ubuntu Edgy i686 with kernel 2.6.17-11-server running Apache 2.0 with PHP5 for Mediawiki, some others stuffs like Tomcat & Jboss. Got Java installed : j2re1.4, j2sdk1.4, java-common, libgcj-common, sun-java5-bin , sun-java5-demo , sun-java5-jdk and sun-java5-jre
In the case of the first server (fresh Ubuntu Gutsy 64bits with almost anything running) it worked fine, I can use Lucene to search into my Wiki. In the case of my second server, here is the error when I would like to start the engine :
www-data@myserver:/usr/local/search/ls2$ ./lsearchd

But NOTHING use the port 8321. I've tried to use another port, it's the same problem. Any ideas how to solve this problem please? Here is my contact :
Thanks, LMJ 15 January 2008
- First verify that jboss, tomcat and lsearchd all run under sun-java5-bin (and not j2re1.4). If this is the case then maybe the RMI registry is colliding with jboss (so try stopping it if you can). If this appears to be the case, then you can either configure jboss not to use the port 1099, or edit RMIRegistry.java to use a different port (replace 1099 there with your port, and provide the port as param to getRegistry() calls in RMIRegistry.java and RMIMessengerClient.java). --Rainman 15:05, 15 January 2008 (UTC)
- Indeed Rainman, thanks for your help! look at this :
# lsof +i :1099 COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME java 20832 syncron 7u IPv4 149877937 TCP *:rmiregistry (LISTEN)
The port is used by Jboss rmiregistry :-/ I need some extra help to change that port. Can we exchange emails about it Rainman? I tried to contact you via your personal page but I just read English & French ;) --16 January 2008
- I've edited
/usr/local/jboss-3.2.7/server/default/conf/jboss-service.xmland change to port to 10999. It seems to work better ;) Got another problem but it seems to be lsearch.conf related issue. --22 January 2008

Daemon status[edit]
On the German Wikipedia, I am often irritated because changes in content are not reflected immediately by the full text search and – at the moment – I cannot see whether and when the changes have already or will be processed by the daemon. Therefore, I would like to know:
- whether the daemon processes the changes chronologically so one could be certain that if one's changes were made at time T and the daemon has processed all changes up to T + 1, they will be reflected in the full text search, and
- whether there is any way to obtain the daemon status (all changes up to T, n articles in queue, etc.) from a current or future Wikipedia installation.
Thanks, Tim Landscheidt 19:52, 7 February 2008 (UTC)
- The index is updated around 5 am GMT every day on wikimedia projects (when nothing goes wrong which is most of the time). About 1) - yes, it processes the changes chronologically. 2) - this interface is available but only for system admins, for everybody else - just wait till tomorrow for changes to be applied. --Rainman 10:07, 8 February 2008 (UTC)
- Hmmm. If I search for "Lassithi" (note the double "s") now, I see that changes in de:Panagia i Kera (8 days ago), de:Kritsa (7 days ago), de:Ierapetra (10 days ago), de:Kera Kardiotissa (11 days ago), de:Griechische Toponyme (11 days ago), de:Venezianische Kolonien (9 days ago) and de:Sitia (11 days ago) have not been processed. Is that what you mean by "when nothing goes wrong"? :-) Would it be technically feasible to include the last time a change was successfully worked into the index in the result page, i. e. "All changes until T considered."? Tim Landscheidt 17:24, 8 February 2008 (UTC)
- Yes, this seems to be a case of "if nothing is broken" :) one of the dewiki search servers (srv21) is broken and stopped updating its index and seems to have a broken logrotate and possibly some other things. We'll fix it when a sysadmin become available. Whenever you see changes not going in for more than a couple of days you should report it. --Rainman 18:07, 8 February 2008 (UTC)
- Ok, we tracked this down to a hard drive failure on srv21, now one just needs to wait for cache to expire (~12h) and you should get fresh results - thanks for the report! --Rainman 18:57, 8 February 2008 (UTC)
- Thanks for the information :-). What would be the proper place to report such things in the future? Tim Landscheidt 21:32, 8 February 2008 (UTC)
- Technical issues are usually reported via IRC channel #wikimedia-tech where all of the sysadmins are. If there's no-one online to fix the problem then you could submit a bug. You could also send me an e-mail via this wiki or leave a message on my talk page, since I'm more-or-less in change of maintaining the search subsystem. --Rainman 21:44, 8 February 2008 (UTC)
- Okay, I'll keep that in mind. Thanks again, Tim Landscheidt 22:53, 8 February 2008 (UTC)

I'm getting this error saying no file or directory. The directory exists, owever I don't know where the "segments" file comes from
I ran this to create the indexes

The wikidb.xml file exists in the httpdocs directory

Am I missing a trick?

- And what is the output from the importer? It should give you a success messages that it created the indexes and successfully made a snapshot. --Rainman 01:30, 20 February 2008 (UTC)
I'm most likely doing something dumb (being a bit of a newbie) but This is what I get when I just run the
java -cp LuceneSearch.jar org.wikimedia.lsearch.importer.Importer -s wikidb.xml kck_wiki

- The java command you're running assumes that LuceneSearch.jar is in your current directory, the full command would be

Do I need to set the OIA settings in the global config? I've just kept them s the default. --Andy 18:30, 20 February 2008 (GMT)
- No, you don't need oai.. Seems to me something is wrong with the xml file .. sure would be helpful if exception weren't suppressed :\ unfortunately cannot help you much more than that.. is wikidb.xml a valid xml file? did you give full path to it? --Rainman 01:00, 21 February 2008 (UTC)

From here, I pull up my normal wiki, which has been working fine ALL along - but now, I get ZERO search results, no matter what I do! I know I am searching correctly, I just type in 1 single word for searching (that I know is on several pages in the wiki) I've even tried to edit the file before and after building the index, and starting/stoping the lsearch daemon, yet I get this error in my MediaWiki search results page;
Search results From AgentDcooper's Wiki You searched for wiki For more information about searching AgentDcooper's Wiki, see Searching AgentDcooper's Wiki. Showing below 0 results starting with #1. No page text matches Note: Unsuccessful searches are often caused by searching for common words like "have" and "from", which are not indexed, or by specifying more than one search term (only pages containing all of the search terms will appear in the result).
I notice that the lsearch daemon console output scrolls the following; right after doing a search within the wiki

Which leads me to my question: what am I doing wrong?? I have tried everything I can think of, I just cannot get my search within my mediawiki to work proplery. It seems like the search itself is working when going to the link directly above -- somehow the "total hits" in the log as well as the wiki are showing ZERO? Yet manually going to the link in the debug, shows me what appears to be a result indicating 3 PAGES were found with corresponding results data!?@# Why is MediaWiki not showing this? Anyhelp would be kindly appreciated, or even a link for reference! -peace- --Agentdcooper 12 May 2008
- I would suspect the problem is the MW version. Search front-end has been heavily refactored in MediaWiki 1.13, and MWSearch is designed to run with latest mediawiki, so there might be some compatibility issues. Note that MW 1.13 is still not released, but is still in development. Try using Extension:LuceneSearch instead. --Rainman 13:20, 12 May 2008 (UTC)
- Thanks a TON, I will try this out in just a few, I half suspected it was a MediaWiki versioning issue, I really need to upgrade! =) --Agentdcooper 20:16, 12 May 2008 (UTC)
- I moved to LuceneSearch and getting a strange error -- I removed MWSearch extension entirely, then downloaded Extension:LuceneSearch SVN from today, and moved the LuceneSeach directory to /var/www/htdocs/wiki - chmod'd to 755 recursively to make sure it isn't a permissions issue - the I commented out the MWSearch code in LocalSettings.php;
#$wgSearchType = 'LuceneSearch';
#$wgLuceneHost = 'localhost';
#$wgLucenePort = 8123;
#require_once("extensions/MWSearch/MWSearch.php");
- I've tried different settings for Extension:LuceneSearch, but ended up with this config for LuceneSearch ;
$wgDisableInternalSearch = true;
$wgDisableSearchUpdate = true;
$wgSearchType = 'LuceneSearch';
$wgLuceneHost = 'localhost';
$wgLucenePort = 8123;
require_once("extensions/LuceneSearch/LuceneSearch.php");
$wgLuceneSearchVersion = 2;
$wgLuceneDisableSuggestions = true;
$wgLuceneDisableTitleMatches = true;
I then ran the indexer, which seemed to go great ;

2008-05-12 :: Installed Mediawiki SVN + Lucene-Search SVN & MWSearch SVN, still getting ZERO search results[edit]
I flat-out installed MW from new version of mediawiki SVN, Lucene-search SVN, and MWSearch SVN Version r34306 -- all subversion/SVN downloads from 05.12.2008, with lucene-search-2 SVN being 05.11.2008).

config/install of new mediawiki SVN I ran thru the basic config/install of mediawiki, and put some data into the basic wiki - something I knew could be searchable easily. I build the index, it seems to build without error, everything just works --- but when I issue a search from the main wiki page, i get ZERO search results, even tho' the mediawiki original search DID find these searches when it was just a basic mediawiki install, prior to me installing Lucene-Search and/or MWSearch extensions.
mediawiki search results = ZERO What seems strange here is everything seems to work, up-to the point of searching thru my wiki! when I search in the wiki, i get the following, ZERO results message ;

HELP :: where am I going wrong??
Mediawiki gives me no results, and the debug log file above, shows a total [0] hits, why am I getting zero hits? no matter what I do, I am getting zero hits!? can you see anything wrong I am doing here? please help =) --Agentdcooper 00:41, 13 May 2008 (UTC)

- OK then, try adding wfDebug($data); somewhere around line 564 in MWSearch.php. This should print to the MediaWiki debug log the same data you're seeing whey you directly access the search URL. If it doesn't print anything, then something is wrong with your curl. --Rainman 09:06, 13 May 2008 (UTC)
- Well, I think you are on to something there! so here's the deal, I put wfDebug($data); on line #565, by itself. I then re-ran the index command, and restarted the lsearch daemon so I could watch the console output via SSH session .... I loaded up the main wiki page, and did a basic search for the word "wiki" here's what happens ;;

- I am going to install slackware v12.1 as a FRESH install on a new computer, and try this all over again, to see if it may be something I messed up along the way, I will report back with my results... In case someone ends up reading the above, and can make a suggestion, I'm all ears! I will be keeping the slackware 12.0 install seperate, and would love to hear from someone on how I might go about fixing it! -peace- --Agentdcooper 20:52, 15 May 2008 (UTC)
currently, i'm updating to newer OS, but is that necessary, REALLY?
I am downloading slackware 12.1 ISO's right now, but it just bewilders me why I would need to have the latest/greatest OS to run mediawiki - as I understood it, mediawiki can run on all sorts of linux based OS's/distributions and doesn't necessarily need to have the best hardware needed to run with... I've detailed my problems heavily above, I am hoping someone can help me, before I get my new, rather large 2.0Gig OS download completed (it'll take a couple days, due to my slow `net connection right now... I'd really like to fix whats broken before updating my entire OS, meh? thanks for all the help so far! --Agentdcooper 03:24, 19 May 2008 (UTC)
Lucene-search wrecks Special:ListUsers[edit]
When using Lucene-search version 2.0.2 (the current version as of this date) under mediawiki 1.10.x, I found that the special page Special:ListUsers stays blank. Turning on error reporting revealed a fatal error:
Fatal error: Class 'ApiQueryGeneratorBase' not found in /srv/www/htdocs/mediawiki/extensions/LuceneSearch/ApiQueryLuceneSearch.php on line 33
I found that this can be solved by adding the line
require_once($IP.'/includes/api/ApiQueryBase.php');
into the file LuceneSearch_body.php (right below the require statement which is already there).

Exception resolution[edit]
If you have an error such as
Exception in thread "main" java.lang.NullPointerException
at java.io.File.<init>(Unknown Source)
at org.apache.lucene.store.FSDirectory.getDirectory(FSDirectory.java:117)
at org.apache.lucene.index.IndexWriter.<init>(IndexWriter.java:204)

at org.wikimedia.lsearch.importer.DumpImporter.<init>(DumpImporter.java:39)
at org.wikimedia.lsearch.importer.Importer.main(Importer.java:128)
when running the index creation, it can be because your host name changed (check $HOSTNAME on command line). In that case, update lsearch-global.conf

LuceneSearch is not available anymore?[edit]
LuceneSearch extension was developed for MediaWiki version 1.12 which IS the current version. But the box on the top of the page says it is not to be used with the current version, and the extension is not available in SVN any more. WHY is that? Am I missing something? Oduvan 13:37, 7 August 2008 (UTC)
- Seems like someone moved around some extensions. I've updated the link on Extension:LuceneSearch to point to right location. --Rainman 19:49, 7 August 2008 (UTC)
Running multiple lsearch daemons[edit]
Hi, I am setting up a server which hosts several wikis. We want to use the lucene search for some of them so I have to config several lsearch daemons.
Although I change the Search.Port variable in the lsearch.conf file (Search.port=8124), and after starting the first lsearch, the second lsearch daemon complains about the port 8123 is being used.
Log from first lsearch:

What I'm doing wrong?
Thanks for your help. --2 October 2008
Hi,
I ran into the same problem, but I found out, that the SearchServer class does not parse the configuration for Search.Port.
The HTTPIndexServer on the other side parses the configuration for Index.port.
I suggest, that ther should be code like the following in the SearchServer class as well.
[...]
public class HTTPIndexServer extends Thread {
[...]
int port = config.getInt("Index","port",8321);
[...]
I will try this out this. Hopefully I will post successful results afterwards.
Regards, -- Voglerp 14:21, 20 October 2008 (UTC)
So here are my test results:
I added the following two lines into the SearchServer class
[...]
public class SearchServer extends Thread {
[...]
org.apache.log4j.Logger log = Logger.getLogger(SearchServer.class);
1 // Read port setting from configfile, if not found set default
2 port = config.getInt("Search","port",8123);
log.info("Searcher started on port " + port);
[...]
Now the Searcher listens to the port specified in the configuration or to the default port 8123. But a new problem is, that it is no longer possible to specify the port on the commandline with -port.
Is it possible to change the code that both options will work?
Kind regards, Peter --Voglerp 08:06, 23 October 2008 (UTC)

need help for small wiki farm[edit]
I have a small wiki farm with to wikis, mywiki-en and mywiki-de running on the same wiki software and sharing the same mysql database wikidb.
The mysql tables for both wikis are prefixed, with en_ or with de_ respectively.
mywiki-en is in English
mywiki-de is in German.
I know how to make two separate dump files, wikidb_en.dump and wikidb_de.dump by using the commands
export REQUEST_URI=/wiki/en && php /wwd/wiki/maintenance/dumpBackup.php --current --quiet > wikidb_en.xml export REQUEST_URI=/wiki/de && php /wwd/wiki/maintenance/dumpBackup.php --current --quiet > wikidb_de.xml
My question is: how do I configure Lucene and mwsearch, so that
- for searches in /wiki/de it uses the indexes created from wikidb_de.xml,
- for searches in /wiki/en it uses the indexes created from wikidb_en.xml
I would not desire that hits in the english wiki show up as serch results for queries in wiki/de, and the other way around.
I also need to know how to configure lsearch-global.conf So far I have written there
[Database] wikidb : (single) (language,en) (warmup,10)
but this is of course not correct: the dabase wikidb contains two wikis, one on German, one in English.
I hope that somebody can help me a bit.
Thank you, Alois 16:06, 29 October 2008 (UTC)
Searching what the user sees or searching what's behind the scenes[edit]
It seems to make no sense to search the unrendered wiki-text rather than the final product.
I don't see why wiki comments ( <!-- such as this --> )should be included in the search but the contents of included templates are not. It really should be the other way round.
For those wikis using the semantic media wiki extension, they also find that the results of inline queries are excluded from the search, that also seems like something that needs to change.
Perhaps there is a place for a search that looks behind the scenes. It may be of interest to a wiki-site manager, but for a standard user the search really needs to be of the actual page contents.

- Agreed that it doesn't. However, it is not a matter of if it makes sense or not, but whether it is difficult or easy to do. There is no easy way to reconstruct articles with templates from very large xml dumps, and no advanced way to integrate updates from OAI with templates, queues and such. This is one of those places where the flexibility of MW in one regard (e.g. syntax and caching) make a huge trade-off with other (ability to have a decent search). --Rainman 02:04, 30 November 2008 (UTC)
Lack of sane defaults[edit]
This extension suffers from a lack of sane defaults, which makes setting it up unnecessarily confusing. I will give some examples from the instructions.
- mwdumper.jar: should be IN subversion. There is no reason to have to checkout the code for the extension and then get another file
- speaking of subversion, the root should be moved up a level. The root should not be 'lucene-search-2' if you are going to ask them to put that in a parent directory called 'search'. The root should be 'search', and it should already contain the 'indexes' subdirectory. The instructions should then read 'svn co http://svn.wikimedia.org/svnroot/mediawiki/trunk/search /usr/local/search'.
- MWConfig.global: specifically asks for a "URL", which have a very specific meaning, and gives an example of only a url. That's great for a multi-host configuration, which most mediawiki installations are not. The default path to this file should be /usr/local/search/ls2/lsearch-global.conf. If this is not an acceptable path, you should say so. The file:/// prefix that is used in these wiki instructions is not what people expect to see.
- MWConfig.lib: Here you use a standard path, which people normally expect. But this is NOT what they expect since you have told them to use 'file:///' in the previous instructions on the wiki (but not in the configuration file). This is confusing!!!!
- Localization.url: Back to the file:/// prefix. AGHHHH. There is no need to specify that it is a file. File paths are unambiguous without file:///.
- Logging.logconfig: There is no reason to prompt the user for the location of this file if you put it in the ls2 directory by default, and make that the default location.
I believe that, up to this point, every single configuration step could have been avoided if there had been sane defaults in place. I don't have the energy to do the rest. --Alterego 18:47, 5 January 2009 (UTC)
- I agree that the configuration is overly complicated, that is why the devel branch has a one-step script that will generate and connect all of the configuration in single-host installs. As for url/local file distinction, it follows a simple rule: everything that is global and shared across the search cluster (e.g. global config and MW files) is url, everything local (e.g. local config, indexes path, local log4j config and library files...) is a local path, although that is probably not obvious from the variable names... --Rainman 19:20, 5 January 2009 (UTC)
LSEARCH Daemon init script for SUSE[edit]
- from Pierre Boisvert.
- this is our init script for the daemon. It is simple but work for us, so it coult help others as well.
