[[default-mapping]] === Default Mapping
Often, all types in an index share similar fields and settings. ((("mapping (types)", "default")))((("default mapping"))) It can be
more convenient to specify these common settings in the _default_ mapping,
instead of having to repeat yourself every time you create a new type. The
_default_ mapping acts as a template for new types. All types created
after the _default_ mapping will include all of these default settings,
unless explicitly overridden in the type mapping itself.
For instance, we can disable the _all field for all types,((("all field", sortas="all field"))) using the
`_defaultmapping, but enable it just for theblog` type, as follows:
PUT /myindex { "mappings": { "_default": { "_all": { "enabled": false } }, "blog": { "_all": { "enabled": true } } }
// SENSE: 070_Index_Mgmt/45_Default_mapping.json
The _default_ mapping can also be a good place to specify index-wide
