We're getting close to fully releasing version 1.0 of the Elasticsearch Learning to Rank plugin. Today our first release candidate for 1.0 is out (for ES 5.6.2)! We need community testing and feedback to help make it bulletproof. Please download it and try it out!

What is Learning to Rank? It applies machine learning to relevance ranking. This plugin is currently serving search results on Wikipedia and Snagajob. It's been codeveloped between OpenSource Connections, Wikimedia Foundation, and Snagajob Engineering. Enjoy!
