Wikimedia Search Platform

The Search Platform team (part of Wikimedia Technology) is responsible for maintaining and enhancing the various Search features and APIs for MediaWiki. This includes the CirrusSearch extension which relies on the search backend used at the Wikimedia Foundation to support Wikimedia projects. Elasticsearch Current work by this team is tracked on this Phabricator workboard (backlog board is here) and on the public Search Analytics Dashboard that monitors and analyze the impact of our efforts, as well as the External Search Traffic dashboard that very broadly looks at where our requests are coming from.

The Search Platform team was formerly part of the Discovery Department in Audiences; but, as part of the re-organization (tune-up) of June 2017, the Search Platform team is now part of Technology.

Goals
The Search Platform team's goals for FY 2018/19 can be found here, and they are part of the entire Technology Department's goals (FY2018/19 Q1).

Wikidata Query Service (WDQS)
Searching structured data on Wikidata is an integral part of Discovery in building the Wikidata query service. It provides a SPARQL API through which tools can access Wikidata. Learn more about the Wikidata query service. Our current work is tracked on this Phabricator workboard and weekly deployments of WDQS are documented on Deployments; while a public WDQS Analytics Dashboard is used to monitor and analyze the impact of our efforts.

APIs
Application Programming Interfaces (APIs) provide developers ways to interact with the MediaWiki software.

API:Search and discovery lists the search APIs available and in development. View our public API Analytics Dashboard to monitor and analyze the impact of our efforts.
