The CirrusSearch extension implements searching for MediaWiki using Elasticsearch.

Elasticsearch is a standalone third-party software you must install as a requirement for this extension. It is a database system that provides search and indexing functionality, where the current text of your wiki pages gets indexed for faster and improved search results. The communication between MediaWiki and ElasticSearch is done through web services.

See also the help page on using this extension.

Goals

  • No native dependencies that would make this difficult to install.

The only dependencies are pure-PHP, MediaWiki extensions, and Elasticsearch itself.

  • Provide a near-real-time search index for wiki pages that's extendable by other MediaWiki extensions.
  • Provide all of the query options MWSearch has given users, and more.

Dependencies

PHP dan cURL

In addition to the standard MediaWiki requirements for PHP, CirrusSearch requires PHP to be compiled with cURL support.

Elasticsearch

You must install Elasticsearch.

Every version of ElasticSearch changes how web services work and causes compatibility problems. You must install the version of Elastic Search compatible with the version of MediaWiki you are currently using:

MediaWiki 1.39+ require Elasticsearch 7.10.2 (6.8.23+ is possible using a compatibility layer ). See this revision for compatibility information with earlier versions of MediaWiki.
Elasticsearch versions before 6.8 are incompatible with PHP 8+.

Take note that a Java installation like OpenJDK is needed in addition. It's best to use the official Elasticsearch Docker image or a self-hosted version. A managed product like Amazon OpenSearch (formerly Amazon Elasticsearch) can work but may require additional configuration depending on its specifics. For example, Amazon OpenSearch only listens for Elasticsearch API requests over HTTPS on port 443 (i.e., it does not expose the default Elasticsearch port 9200), so a TLS-enabled proxy (e.g., Nginx) can enable CirrusSearch to communicate with an Amazon OpenSearch cluster.

Elastica
  • Elastica is a PHP library that makes CirrusSearch talk to Elasticsearch. Install Elastica per the instructions below.

Lainnya
  • Due to the actual handling of jobs by the CirrusSearch extension, it is advisable to set up jobs in Redis to prevent messages like Notice: unserialize(): Error at offset 64870 of 65535 bytes in JobQueueDB.php and subsequent errors like Unsupported operand types.

Lihat task T157759.

Pemasangan

Even though the instructions below tell you only to run Composer when installing from git, it may be necessary to issue it anyway to install all PHP dependencies.

  • Unduh dan letakkan berkas-berkasnya di dalam sebuah direktori yang bernama Elastica di folder extensions/ Anda.
    Developers and code contributors should install the extension from Git instead, using:cd extensions/
    git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/Elastica
  • Hanya ketika memasang dari git, jalankan Composer untuk memasang dependensi PHP, dengan menjalankan composer install --no-dev di direktori ekstensi. (Lihat task T173141 untuk komplikasi yang mungkin terjadi.)
  • Tambahkan kode berikut di bagian bawah LocalSettings.php Anda:
    wfLoadExtension( 'Elastica' );
    
  • Yes Selesai – Telusuri ke Special:Version di wiki Anda untuk memastikan ekstensinya berhasil dipasang.

CirrusSearch

  • Unduh dan letakkan berkas-berkasnya di dalam sebuah direktori yang bernama CirrusSearch di folder extensions/ Anda.
    Developers and code contributors should install the extension from Git instead, using:cd extensions/
    git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/CirrusSearch
  • Hanya ketika memasang dari git, jalankan Composer untuk memasang dependensi PHP, dengan menjalankan composer install --no-dev di direktori ekstensi. (Lihat task T173141 untuk komplikasi yang mungkin terjadi.)
  • Tambahkan kode berikut di bagian bawah LocalSettings.php Anda:
    wfLoadExtension( 'CirrusSearch' );
    
  • Now follow the setup instructions in the CirrusSearch README delivered with your extension i.e. $IP/extensions/CirrusSearch/README. Note that all info in it might not apply to your version of the extension, especially the version of Elasticsearch supported.
  • Configure as required.
  • Yes Selesai – Telusuri ke Special:Version di wiki Anda untuk memastikan ekstensinya berhasil dipasang.

Enable regex queries

This is an optional step. You will need to install the search-extra plugin for this. Do so by following these steps:

  1. execute the following command:
    /usr/share/elasticsearch/bin/elasticsearch-plugin/elasticsearch-plugin install org.wikimedia.search:extra:7.10.2-wmf12
    
  2. add the following line to your LocalSettings.php file:
    $wgCirrusSearchWikimediaExtraPlugin[ 'regex' ] = [ 'build', 'use', 'max_inspect' => 10000 ];
    
  3. restart Elasticsearch with the following command:
    systemctl restart elasticsearch
    
  4. recreate the search index by executing the following commands:
    1. php path/to/extensions/CirrusSearch/maintenance/UpdateSearchIndexConfig.php --startOver
      
    2. php path/to/extensions/CirrusSearch/maintenance/ForceSearchIndex.php
      

Upgrading

Please follow the upgrade instructions in the CirrusSearch UPGRADE file.

Configuration

The configuration parameters of CirrusSearch are documented at the "settings.txt" file. See also documentation on CirrusSearch configuration profiles.

Elasticsearch will fail to index for CirrusSearch if one uses a database name for MySQL containing a capital character, e.g., "MyWikiDatabaseName." To mitigate this, CirrusSearch provides the $wgCirrusSearchIndexBaseName configuration parameter, which one needs to set, e.g., $wgCirrusSearchIndexBaseName = 'mywikidatabasename';.

Hooks

CirrusSearch extension defines a number of hooks that other extensions can make use of to extend the core schema and modify documents. The following hooks are available:

API

CirrusSearch features can be used in API queries. Searching happens via the normal search API, action=query&list=search; you can use CirrusSearch-specific features, such as the morelike: special prefix to find pages related to Marie Curie and radium:

api.php?action=query&list=search&srsearch=morelike:Marie_Curie%7Cradium&srlimit=10&srprop=size&formatversion=2

Custom APIs and parameters are provided for querying CirrusSearch configuration and debug information:

Local development

Elastic Search service can be run with the Vagrant role (cirrussearch) and MediaWiki Vagrant.

For Docker, you can use a command like docker run -d --name elasticsearch -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" elasticsearch:6.8.2. Then follow the installation and configuration directions. If your web host is in a container, you'll want to make sure the above container is on the same network, and in the LocalSettings.php file, you will want to reference the elasticsearch as the hostname. This will not have the WMF plugins but can be sufficient for basic testing.
