Extension:CirrusSearch/ja

CirrusSearch 拡張機能はElasticsearchを使った MediaWiki 検索を実装します.

This page is for installation. After the install is working, see for usage.

プロジェクトの目標

 * 奇妙な依存関係がなくてもインストールが簡単にできること
 * 唯一の依存関係は pure-PHP MediaWiki 拡張機能と Elasticsearch だけ
 * 他の MediaWiki 拡張機能で拡張できるウィキページについて、ほぼリアルタイムに検索インデックスを返す
 * が利用者に開放したクエリオプションすべてと、その他を提供

依存関係

 * PHP and cURL
 * In addition to the standard MediaWiki requirements for PHP, CirrusSearch requires PHP to be compiled with cURL support.
 * Elasticsearch
 * You will need to install Elasticsearch.


 * Elastica
 * Elastica is a PHP library to talk to Elasticsearch. Install Elastica per the instructions below.


 * Other
 * Due to the actual handling of jobs by the CirrusSearch extension, it's 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. See.
