Moving the Marketplaces to Elasticsearch - We build Envato
A very interesting feedback on Solr vs ElasticSearch. Mainly deals with indexing and search performance.

ElasticSearch - Open Source, Distributed, RESTful Search Engine
A distributed, highly available and restful search engine. It looks very promising and rather easy to deploy and have working. The killer feature : schema-less indexing (auto-discovery based on conventions). A serious concurrent to Solr ?
