**What is ElasticSearch Mapping:**

Mapping is the process of defining how a document and the fields it contains are stored and indexed. For instance, mappings are used to define:

* **Which string fields should be treated as full text fields.**
* **Which fields contain numbers, dates, or geolocations.**
* **The format of date values.**
* **Custom rules to control the mapping for dynamically added fields.**
