Mappings

To understand mappings, let's add another product to the product catalog:

PUT /catalog/product/2{    "sku": "SP000002",    "title": "Google Pixel Phone 32GB - 5 inch display",    "description": "Google Pixel Phone 32GB - 5 inch display (Factory Unlocked US Version)",    "price": 400.00,    "resolution": "1440 x 2560 pixels",    "os": "Android 7.1"}

Copy and paste this example into the editor of your Kibana Console UI and execute it.

As you can see, the product has many different fields, as it is of a completely different category. Yet, there are some fields that are common in all products. The common fields are the precise reason why all these documents are called products. 

Remember, unlike relational databases, we didn't have to define the fields ...
