Elasticsearch is a Lucene/Java-based search engine that offers full-text search and analytics (Wikipedia). Once installed on the server, it is ready for integration with MediaWiki through the use of dedicated extensions. The CirrusSearch extension lets you enable it to replace the native search engine that comes with MediaWiki. Elasticsearch can also be used with other extensions to store structured data and to provide a richer search experience.

Installing and configuring Elasticsearch[edit]

Some companies specialised in hosting wikis offer Elasticsearch as part of their services.
