"Elasticsearch is distributed, which means that indices can be divided into shards and each shard can have zero or more replicas. Each node hosts one or more shards, and acts as a coordinator to delegate Elastic is a search server based on lucene and provides a distributable full text search engine that’s accessible through a restful interface.
