Documents
- Documents are JSON objects that are stored within an Elasticsearch index and are considered the base unit of storage.
- In a relational database, documents can be compared to a row in table.
- For example, if you are running an e-commerce application. You could have one document per product or one document per order. There is no limit to how many documents you can store in a particular index.
- Data in documents is defined with fields comprised of keys and values. A key is the name of the field, and a value can be an item of several types such as a string, a number, a Boolean expression, another object, or an array of values.
- Additionally, Documents contain reserved fields that establish the document metadata such as:
- _index - The index where the document exists in.
- _type - The type that the document denotes.
- _id - The unique identifier for the document.
