Elasticsearch is a new generation Open Source search and indexing engine. Based on the Apache Lucene library, this search engine offers advanced features such as searches by geographic coordinates, analysis and categorization aggregations, filtering results or searching on several different indexes and types of documents. Designed for the Cloud, Elasticsearch has been specifically designed to index very large volumes of data while ensuring high performance scalability and high fault tolerance.
This course covers key concepts of search engines before detailing the basic features of ElasticSearch and its architectural principles. Based on concrete examples and actual use cases, the training provides all the necessary knowledge to use and operate ElasticSearch effectively and to solve the problems most often encountered.
