In this talk, Radu Gheorghe, from Sematext, gives an Introduction to Elasticsearch. Radu starts out by talking on what Elasticsearch is and how it can act as your NoSQL data-store while providing quick, flexible and scalable search. For example, indexing logs or storing product information so that customers can search on them. Radu also delivers a demo which will display the most important functions of Elasticsearch. Some key talking points will be indexing and searching for documents, text analysis for tweaking the relevance of your searches and the facets that allow for pulling statistics out of documents as well as scaling out which offers for more capacity and fault tolerance. He will also touch base on performance tuning for indexing and monitoring as well as administering your cluster in production. This talk was recorded at the NYC Search, Discovery and Analytics meetup at Gilt.
