By

ElasticSearch is an open source, RESTful search engine built on top of Apache Lucene and released under an Apache license. It is Java-based and can search and index document files in diverse formats.

ElasticSearch has been compared to Apache Solr and offers several notable features:

  • Provides a scalable search solution.
  • Performs near-real-time searches.
  • Provides support for Multi-tenancy.
  • Streamlines backup processes and ensures data integrity.
  • An index can be easily recovered in a case of a server crash.
  • Uses Javascript Object Notation (JSON) and Java application program interfaces (APIs).
  • Automatically indexes JSON documents.
  • Indexing uses unique type-level identifiers.
  • Each index can have its own settings.
  • Searches can be done with Lucene-based querystrings.
