CirrusSearch is a search extension that supports more complex search phrases. It uses ElasticSearch to store data.



=ElasticSearch Install=

For installation on mediawiki 1.35:

* Install java8 and [https://www.elastic.co/guide/en/elasticsearch/reference/6.8/getting-started-install.html#successfully-running-node elasticsearch 6.8.23]

** <code>apt-get install openjdk-8-jre-headless</code>

** <code>echo "deb https://artifacts.elastic.co/packages/6.x/apt stable main" | sudo tee -a /etc/apt/sources.list.d/elastic-6.x.list</code>

**<code>sudo apt-get update && sudo apt-get install elasticsearch</code>

* Install the Elastica and CirrusSearch (use the same version as your MediaWiki version) extensions [https://www.mediawiki.org/wiki/Extension:CirrusSearch]

* Follow instructions in ./extentions/CirrusSearch/README



=MediaWiki LocalSettings=

** Add this to LocalSettings.php

 wfLoadExtension( 'Elastica' );

 wfLoadExtension( 'CirrusSearch' );

 $wgDisableSearchUpdate = true;

:*<code>php7.4 ./extensions/CirrusSearch/maintenance/UpdateSearchIndexConfig.php</code>

:*Remove <code>$wgDisableSearchUpdate = true</code> from LocalSettings.php

:*<code>php7.4 ./extensions/CirrusSearch/maintenance/ForceSearchIndex.php --skipLinks --indexOnSkip</code>

:*<code>php7.4 ./extensions/CirrusSearch/maintenance/ForceSearchIndex.php --skipParse</code>

:*Edit LocalSettings.php to have <code>$wgSearchType = 'CirrusSearch';</code>



Check [[Special:Version]] to see if all is installed



To verify CirrusSearch is used add '&cirrusDumpQuery' to a search URL. A json-string will be shown.



=ElastichSearch Tips=



==Remote ElasticSearch server==

If ElasticSearch is on another server as the webserver you have to edit /etc/elasticsearch/elasticsearch.yml to listen to the outside address

 network.host: <outside IP address>



==Start/Stop script==

For automatic start/stop I created /etc/init.d/elasticsearch like

<syntaxhighlight lang=bash>

#!/bin/sh

# kFreeBSD do not accept scripts as interpreters, using #!/bin/sh and sourcing.

if [ true != "$INIT_D_SCRIPT_SOURCED" ] ; then

    set "$0" "$@"; INIT_D_SCRIPT_SOURCED=true . /lib/init/init-d-script

fi

### BEGIN INIT INFO

# Provides:          elasticsearch

# Required-Start:    $remote_fs $syslog

# Required-Stop:     $remote_fs $syslog

# Default-Start:     2 3 4 5

# Default-Stop:      0 1 6

# Short-Description: Start ElastichSearch deamon

# Description:       Start ElastichSearch deamon

#                    This script starts a

#                    single forking daemon capable of writing a pid

#                    file.  

### END INIT INFO



# Author: Hans de Ridder <hans@deridder.it>

#



if [ `id -nu` != 'elasticsearch' ]

then

 su elasticsearch $0 $*

 exit

fi 



DESC="ElasticSearch engine"

DAEMON="/opt/elasticsearch/bin/elasticsearch"

DAEMON_ARGS="-d"

</syntaxhighlight>



Now you can start by <code>service elasticsearch start</code>. Stopping is not implemented in this script.



In /etc/rc5.d do <code>ln -s ../init.d/elasticsearch S02elasticsearch</code>



==Troubleshooting==

;curl  <nowiki>http://localhost:9200/_aliases?pretty=true</nowiki>

:List the indexes in elasticsearch

;curl -XDELETE <nowiki>http://localhost:9200/<indexname>*/</nowiki>

:Remove all indexes where name starts with <indexname>
