Elasticsearch is a search engine based on Apache Lucene, a free and open-source search engine. It provides a distributed, multitenant -capable full-text search engine with an HTTP web interface and schema-free JSON documents.
The difference [contradictory] lies in the way the data is processed; in a key-value store, the data is considered to be inherently opaque to the database, whereas a document-oriented system relies on internal structure in the document in order to extract metadata that the database engine uses for further optimization.
[2] [3] It was founded in 2012 in Amsterdam, the Netherlands, and was previously known as Elasticsearch. [ 4 ] The company develops the Elastic Stack— Elasticsearch , Kibana , Beats, and Logstash—previously known as the ELK Stack, [ 5 ] free and paid proprietary features (formerly called X-Pack), Elastic Cloud (a family of SaaS offerings ...
A data structure known as a hash table.. In computer science, a data structure is a data organization and storage format that is usually chosen for efficient access to data. [1] [2] [3] More precisely, a data structure is a collection of data values, the relationships among them, and the functions or operations that can be applied to the data, [4] i.e., it is an algebraic structure about data.
Kibana also provides a presentation tool, referred to as Canvas, that allows users to create slide decks that pull live data directly from Elasticsearch. [ 5 ] The combination of Elasticsearch, Logstash , and Kibana, referred to as the " Elastic Stack " (formerly the "ELK stack"), is available as a product or service. [ 6 ]

In computer science, an inverted index (also referred to as a postings list, postings file, or inverted file) is a database index storing a mapping from content, such as words or numbers, to its locations in a table, or in a document or a set of documents (named in contrast to a forward index, which maps from documents to content).
