Mission: To provide advanced and scalable search across multi-tenant cloud resources.

This improves the performance of OpenStack API services while dramatically improving search capabilities. It does this by offloading user search queries from existing API servers and utilizing technologies designed for large-scale searching. The desired user experience is greatly dependent upon a rich, dynamic, near real-time faceted and aggregated search capability with a strong query language.

The service is initially based on Elasticsearch. Elasticsearch is a search server based on Lucene. It provides a distributed, scalable, near real-time, faceted, multitenant-capable full-text search engine with a RESTful web interface and schema-free JSON documents. Elasticsearch is developed and released as open source under the terms of the Apache License. Notable users of Elasticsearch include Wikimedia, StumbleUpon, Mozilla, Quora, Foursquare, Etsy, SoundCloud, GitHub, FDA, CERN, and Stack Exchange.
