== Dynamic mapping
|
|
|
|
One of the most important features of {es} 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 display automatically:
|
|
|
|
[source,console]
|
|
--------------------------------------------------
|
|
PUT data/_doc/1 <1>
|
|
{ "count": 5 }
|
|
--------------------------------------------------
|
|
|
|
<1> Creates the `data` index, the `_doc` mapping type, and a field
|
|
called `count` with data type `long`.
|
|
|
|
The automatic detection and addition of new fields is called
|
|
_dynamic mapping_. The dynamic mapping rules can be customized 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: <<index-templates,Index templates>> allow you to configure the default
|
|
mappings, settings and aliases for new indices, whether created
|
|
automatically or explicitly.
