Wikimedia Platform Engineering/MediaWiki Core Team/Backlog/Project/CirrusSearch

Outline
CirrusSearch has many user-facing improvements over LuceneSearch:
 * Changes to articles reflected in search results much faster
 * Built-in better support for languages than LuceneSearch, including support for many languages that were previously unsupported
 * Templates expanded, so transcluded text can be included in search results

Stakeholders

 * All users of Wikimedia cluster
 * All third-party users of MediaWiki

Acceptance criteria

 * CirrusSearch deployed everywhere on Wikimedia cluster
 * LuceneSearch deprecated and CirrusSearch bundled with default MediaWiki package
