Documents

The basic unit of information that is stored in Elasticsearch is called a document. You can consider a document equivalent to an entity in the relational database management system (RDBMS). For example, a document can be created for an employee, another document is for a salary, and so forth. A document will be indexed by the Elasticsearch engine, and they are presented in JSON format. Each document is associated with the document type. You can relate a document type with a Plain Old Java Object (POJO) class while a document as an object of POJO class.
