- == Dynamic Mapping
- One of the most important features of Elasticsearch is that it tries to get
- out of your way and let you start exploring your data as quickly as possible.
- To index a document, you don't have to first create an index, define a mapping
- type, and define your fields -- you can just index a document and the index,
- type, and fields will spring to life automatically:
- [source,js]
- --------------------------------------------------
- PUT data/_doc/1 <1>
- { "count": 5 }
- --------------------------------------------------
- // CONSOLE
- <1> Creates the `data` index, the `_doc` mapping type, and a field
- called `count` with datatype `long`.
- The automatic detection and addition of new fields is called
- _dynamic mapping_. The dynamic mapping rules can be customised to suit your
- purposes with:
- <<dynamic-field-mapping,Dynamic field mappings>>::
- The rules governing dynamic field detection.
- <<dynamic-templates,Dynamic templates>>::
- Custom rules to configure the mapping for dynamically added fields.
- TIP: <<indices-templates,Index templates>> allow you to configure the default
- mappings, settings and aliases for new indices, whether created
- automatically or explicitly.
