Elasticsearch is a search server based on Lucene. It provides a distributed, multitenant-capable full-text search engine with a RESTful web interface and schema-free JSON documents. Elasticsearch is developed in Java and is released as open source under the terms of the Apache License. We'll cover using Elasticsearch in Azure using the .NET API. We'll cover: • Elasticsearch basics • Setting up a development environment • Loading data • Searching data using REST • Searching data using NEST, the .NET interface • Understanding Scores You'll walk away from this armed with the knowledge to add Elasticsearch to your data analysis toolkit and you applications. If time permits, I'll overview a real-world implementation of ES in Azure to mine unstructured data.
