Is there an option for the database tables prefix?

edit

My wiki uses prefixes for the tables in the database.

$wgDBprefix = "mw";

Is there an option to set the prefix in the properties file?

Answer
  1. see patch offer. Unfortunately the package is currently not well maintained.
  2. workaround: copy the database tables $wgDBprefix{page,revision,text,image} to page, revision, text, image before starting the loader.sh and drop/remove them afterwards.

Do we not have to schedule re-run of loader.sh

edit

The installation notes say that it only has to be run on startup. Do we not have to run this on a schedule to ensure that new documents / content are added to the index ?

Search Inside Documents

edit

I don't seem to be indexing the text inside MSWord, MSExcel, etc documents, is that possible?

Prerequisites

Given that version 1.14 changed the way MediaWiki handles files, does anyone have any experiences getting this extension to work with it? thanks

The extension also fails in 1.15 for the same reason i believe. Making symbolic links to simulate previous image folder structures seem to work. However I'm getting loads of XML tag mismatch errors when using the search :

Warning: DOMDocument::loadXML() [domdocument.loadxml]: Premature end of data in tag HTML line 2 in Entity, line: 50 in /export/home/www/default/wiki/extensions/EzMwLucene/EzMwLuceneSearchEngine.php on line 116 Notice: Trying to get property of non-object in /export/home/www/default/wiki/extensions/EzMwLucene/EzMwLuceneSearchEngine.php on line 147

Why would I use this instead of Lucene? Is it easier to install? --Robinson Weijman 10:04, 4 March 2010 (UTC)Reply

Two reasons:
  • Much easier to install, especially on windows box.
  • This extension can index uploaded files (pdf, doc) OOTB, while with Lucene you would really have to break a sweat to make it work.

--Gregra 10:08, 4 March 2010 (UTC)Reply

Great, thanks for your prompt response. I suggest you add these two reasons to the article page. --Robinson Weijman 10:03, 5 March 2010 (UTC)Reply

Where's actually the EzMwLucene Installation Guide? The link in the extension page is broken!

Yikes. It's still broken. Anyone got a viable link? -Whidmark 20:13, 5 April 2011 (UTC)Reply

Is there any place where I can find the installation guide ?

MW/Lucene Search - made easy?

edit
Latest comment: 14 years ago1 comment1 person in discussion

The Title of this extension suggests that following the guide, setup of the Lucene search engine for MediaWiki, would be a relatively EASY or simple process.

It is not.

I thought it was difficult (certainly possible, and with good results) to setup Lucene Search the old way, but this new method introduces a whole new meaning to the words "BROKEN EXTENSION".

No real distribution awareness was undertaken by the author of this extension. Startup scripts outright dont work, as they're not UNIX files (can be fixed, i know).. Dont bother. It's actually EASIER to follow your nose and go for the original MWSearch/Lucene Search setup guide. You will have to modify the instructions in order to get it working for your distribution, and probably MW version, but it does work - I've got it running on 2 Live Production Wiki's right now.

This method throws nothing but Java errors and missing class warnings after I finally got it working at filesystem level, and got it talking to the Database. I seriously can not be bothered troubleshooting other peoples bad or missing Java code, so I quit trying. (After making sure that I didn't have any FILES missing). I *know* the other way works (originial MWSearch/LuceneSearch), and I will attempt to get a definitive guide up regarding this. Until then, you're better off without EzMwLucene.

Version

edit

Did you look at the version information and the fact that this is a beta extension? It has not been updated to more recent versions of Mediawiki. I cannot speak to the ease of the original LuceneSearch now, but two years ago when this extension was written it was not easy. I know that Brion Vibber liked this extension and was planning on integrating some of the features into LuceneSearch, but again, I don't know the status of it. --Cmreigrut 18:11, 10 June 2010 (UTC)Reply

even a beta extension should have at least the possibility to work. This one does not work at all, simply because for the java service, there is no main function to start it. Whatever is running elsewhere, it is not the same .jar file.

Running EzMWLucene under Debian

edit

To run this extension automatically on Debian startup create the file /etc/init.d/lucene and paste the following code (I hope this is correct, since I'm not a Debian guru): 

#!/bin/sh

JAVA=$JAVA_HOME/bin/java
EZMWLUCENE_HOME=/usr/share/lucene
EZMWLUCENE_PID=/var/run/ezmwlucene.pid

CLASSPATH="$EZMWLUCENE_HOME/ezmwlucene.jar:$EZMWLUCENE_HOME/lib/jetty-6.1.14.jar:$EZMWLUCENE_HOME/lib/jetty-util-6.1.14.jar:$EZMWLUCENE_HOME/lib/servlet-api-2.5-6.1.14.jar:$EZMWLUCENE_HOME/lib/commons-codec-1.3.jar:$EZMWLUCENE_HOME/lib/commons-httpclient-3.1.jar:$EZMWLUCENE_HOME/lib/commons-logging.jar:$EZMWLUCENE_HOME/lib/FontBox-0.1.0-dev.jar:$EZMWLUCENE_HOME/lib/lucene-core-2.4.0.jar:$EZMWLUCENE_HOME/lib/lucene-highlighter-2.4.0.jar:$EZMWLUCENE_HOME/lib/PDFBox-0.7.3.jar:$EZMWLUCENE_HOME/lib/poi-3.5-beta3-20080926.jar:$EZMWLUCENE_HOME/lib/poi-scratchpad-3.5-beta3-20080926.jar"

JAVA_OPTIONS="$JAVA_OPTIONS -Dezmwlucene.home=$EZMWLUCENE_HOME -Djava.io.tmpdir=$TMP"

RUN_ARGS="$JAVA_OPTIONS -cp $CLASSPATH net.sourceforge.ezmwlucene.service.EzMwLuceneService"

case "$1" in
  start)
        echo -n "Starting EzMwLucene: "
		start-stop-daemon --start --pidfile $EZMWLUCENE_PID -d $EZMWLUCENE_HOME -b -m -a $JAVA -- $RUN_ARGS 
		exit 0
		;;

  stop)
        echo -n "Stopping EzMwLucene: "
		start-stop-daemon --stop --pidfile $EZMWLUCENE_PID -d $EZMWLUCENE_HOME -a $JAVA -s HUP 
		exit 0
        ;;

  restart)
		start-stop-daemon --stop --pidfile $EZMWLUCENE_PID -d $EZMWLUCENE_HOME -a $JAVA -s HUP 
		start-stop-daemon --start --pidfile $EZMWLUCENE_PID -d $EZMWLUCENE_HOME -b -m -a $JAVA -- $RUN_ARGS 
		exit 0
        ;;

*)
	echo "Usage: $0 {start|stop|restart} "
    exit 1
	;;
esac

exit 0

Thanks for this, that great. I had to set 

JAVA=$JAVA_HOME/usr/bin/java

to get it to work on a Turnkey Linux Mediawiki Virtual Machine.

Alterego's bugs

edit
Latest comment: 10 years ago6 comments3 people in discussion

These are the bugs I've found with this extension using Kubuntu Jaunty Jackal and MediaWiki 1.16alpha (r50407) --Alterego 00:31, 10 May 2009 (UTC)Reply

Search does not return all results

edit

Search for "Android" you expect to see all Android.*. But it only returns Android.NPE.

Search for "javadoc" you expect to see "javadoc.url". But it doesn't get any result. If search for the whole word of "javadoc.url", it can get the result expected.

It seems that partial word search for any word with dot is not working well.

Is it a known bug, or a configuration I can change?

Problem with Searching Japanese Characters

edit

If I search Japanese characters, I always get "No page text matches" even though the pages exist.

If one of the Search results (by searching English words) contains Japanese characters, they all show as question marks (?????????).

Is this a bug, or a problem of my configuration? Any idea would be greatly appreciated.

workaround

This can be overcome by adding the following code to extensions/EzMwLucene/EzMwLuceneSearchEngine, just inside the searchText() method (before any other code). I am not good with diff, if someone can make a real patch to illustrate this, it may be helpful. 

    if (empty($term)){
        wfDebugLog('EzMwLucene', "SearchEngine::searchText: term is empty, returning a blank result set");
	return new EzMwLuceneSearchResultSet(false);
    }

Loading Special:Search

edit

The following error is repeated 25 times after first loading Special:Search (searches do work, however)

 

This can be supressed by setting 

error_reporting = E_COMPILE_ERROR|E_ERROR|E_CORE_ERROR

in php.ini

Thanks! This method also fixes my warning messages below on the Special:Search page.

Distribution does not include README/INSTALL files

edit

The documentation for this distribution should be included in the package itself, not just on SourceForge which is extremely inconvenient. http://sourceforge.net/docman/display_doc.php?docid=179038&group_id=254413

It also be acceptable to put the documentation on this wiki page, and have the README link here. It would be really nice to have everything hosted in wikimedia's svn.

Indead of applying the "patch" with some command like "$ patchphp EzMwLuceneIndexer.php < the_code_above.php", I just simply edited the EzMwLuceneIndexer.php file, and replace the single line of "-" with the line of "+".
It works!
--User:209.217.94.93 15:59, 4, November 2009 (UTC)
I applied the patch which allowed me to get past the non-object error but the resulting File: page is missing File, File history, and File usage sections. I now can only access the uploaded file by going to the Special:ListFiles page and clicking on the file link. Has anyone fixed this?

Extension is mispackaged

edit

The correct way to pack a tarball is such that when you unpack it, it contains the following directory structure: 

EzMwLucene_1.0/
               client/
               server/

It is rude to put client and server at the top level of the package.

More unicode mishandling

service.sh always fails (with FAIL)

edit

Running $RUN_CMD from the command-line directly, and then backgrounding it and disowning it, works just fine. That bash script you borrowed from another software package simply does not work on my OS, however. The shell script looks portable and expertly written; nontheless it depends on subtle run conditions that are not easy to debug and do not appear to be useful. Modern linux operating systems do not need a shell script to start/stop/restart processes - that is a job for the system to handle. I start the process in the following way. Note that after the long java command comes & disown % This tells bash to background the process and disown it. You should put that in a file in /etc/init.d so that it gets started with your system.

EzMwLucene started!
service.sh really should report success or failure in its output. It does put error messages into the error log though. I got this working by doing the following:
  1. Made a lucene user/group for the system, with the lucene user having a shell of /bin/bash and a home directory of /apps/lucene/home/lucene (ownership lucene:lucene 600)
  2. I put the server directory at: /apps/lucene/server (ownership of files/directories is root:root, except for ezmwlucene.properties which is root:lucene; everything is world readable except for ezmwlucene.properties, which is 640)
  3. I set the following variables in service.sh:
    EZMWLUCENE_HOME="/apps/lucene/server"
    EZMWLUCENE_LOG="/apps/lucene/home/lucene/ezmwlucene.log"
    EZMWLUCENE_USER="lucene"
  4. I installed java 1.6 instead of 1.5
  5. I created /data/lucene (ownership lucene:lucene 600)
  6. In ezmwlucene.properties, I set the following (notice I didn't specify a port for the database url, this tells it to use a socket):
    lucene.index = /data/lucene/index
    server.port = 8080
    mediawiki.name = <Wiki Name>
    mediawiki.databaseUrl = jdbc:mysql://localhost/<databasename>
    mediawiki.databaseUser = <databaseuser>
    mediawiki.databasePassword = <dbpassword>
    mediawiki.imagesUrl = https://fully.qualified.servername/wiki/images/
    mediawiki.localImagesUrl = file:///data/wiki/images/
  7. I ensured that the lucene user could read /data/wiki/images and all images below (my permissions are fairly strict)
    setfacl -R -d -m user:lucene:rX /data/wiki/images
    setfacl -R -m user:lucene:rX /data/wiki/images
  8. I ensured that I could pull images from https://fully.qualified.servername/wiki/images/:
    curl -k "https://fully.qualified.servername/wiki/images/5/58/Test.pdf"
  9. I put the following into LocalSettings.php:
    $wgEzMwLuceneQueryUrl = 'http://localhost:8080/query';
    $wgEzMwLuceneIndexUrl = 'http://localhost:8080/index';
    $wgSearchType = 'EzMwLuceneSearchEngine';
    require_once("extensions/EzMwLucene/EzMwLucene.php");
    $wgDebugLogGroups["EzMwLucene"] = "/tmp/ezmwlucene.log";
  10. I applied the patch to EzMwLuceneIndexer.php, as listed in one of the comments above
After doing the above, I started service.sh (check /apps/lucene/home/lucene/ezmwlucene.log for errors to ensure it started properly, and check netstat to ensure it is actually running). Then I started uploading pdfs and docs and such to test with. Check /tmp/ezmwlucene.log, /apps/lucene/home/lucene/ezmwlucene.log, and your web server logs to ensure that updates are being sent to the daemon, the daemon can pull URLs from the web server, and that the daemon is successfully accessing the files.

Uploading a new pdf does not cause it to get indexed

edit

When I ran loader.sh there was a pdf on the wiki with the title: "Family history of heart attack as an independent predictor of death due to cardiovascular disease". Searching for this title returned the pdf. I then proceeded to delete the pdf, which deleted it from the index. I then re-uploaded it again which did not cause it to show up again in the index.

This worked for me, but it wasn't exactly easy to get it working. Check your logs througoughly.

files are not searched by default

edit

It appears that every single user will have to set their preferences to search the file namespace. 

$wgNamespacesToBeSearchedDefault = array(
    NS_MAIN => true,
    NS_FILE => true,
);

This is from the MW FAQ but it doesn't actually work.. This did work for all users however: 

UPDATE user SET user_options = REPLACE(user_options, 'searchNs14=0', 'searchNs14=1');

Unfortunately, while this changes the preference it does not cause the File namespace to be actually searched

Here's an IRC log on this issue which suggests upgrading past 48811 might help: 

<prefrontal> this seems to have no effect whatsoever on my wiki! http://www.mediawiki.org/wiki/Manual:$wgNamespacesToBeSearchedDefault
<prefrontal> i even set NS_MAIN => false
<prefrontal> it still searches main!
<werdna> what version?
<prefrontal> 48811
<prefrontal> search preferences don't seem to matter either
* Rdsmith4 has quit (".")
<werdna> long story
<prefrontal> huh, i just tested that it works on Wikipedia. wtf
<werdna> but the short answer is that changes to preference defaults will only apply to existing users after r48811
<werdna> I fixed the bug myself
<prefrontal> lol
<prefrontal> ok, i guess i'll upgrade a revision?
<prefrontal> i try to stay in sync w/ WP
<werdna> you'll need to upgrade a few revisions

Indeed - upgrading to MediaWiki trunk in addition to using $wgNamespacesToBeSearchedDefault works.

PDF logo is pointless!

--Alterego 00:22, 10 May 2009 (UTC)Reply

When combined with the PDF handler, is it possible that this is less pointless?

Windows + MySQL + IIS

Latest comment: 11 years ago1 comment1 person in discussion

Does EzMwLucene work on windows, with MySQL and IIS? I get the following exception with the following configuration, and I get the feeling it's because I'm not using apache. Although it might also be related to my localImagesUrl setting ... Any help would be greatly appreciated.

Here's my properties: 

lucene.index = E:\\ezmwlucene_1.0\\server\\index

server.port = 8080

mediawiki.name = RD Suite Project Team Wiki
#mediawiki.databaseDriverClass = com.mysql.jdbc.Driver
mediawiki.databaseUrl = jdbc:mysql://localhost:3306/WikiMySQL
mediawiki.databaseUser = admin
mediawiki.databasePassword = *******
mediawiki.imagesUrl = http://172.21.37.254/MySQL/images
mediawiki.localImagesUrl = file://E:/MediaWikiSQL/images

And this is the exception: 

select page_id as id, rev_timestamp as timestamp, rev_user_text as user, '' as n
amespace,  page_title as title, old_text as content, concat('file://E:/MediaWiki
SQL/images', left(md5(img_name),1), '/', left(md5(img_name),2), '/', img_name) a
s attachmentUrl, rev_comment as comment, page_namespace as namespaceId, rev_user
 as userId from page join revision on page_latest = rev_id join text on rev_text
_id=old_id left join image on (page_title=img_name and page_namespace=6) where n
ot page_is_redirect AND page_namespace >= 0 order by namespaceId, title ;
