|
|
has been limited to 10.

==== Removal of types
|
|
|
|
The typed REST endpoints of the Put Mapping, Get Mapping and Get Field mapping
|
|
APIs have been removed in favour of their typeless REST endpoints, since indexes
|
|
no longer contain types, these typed endpoints are obsolete.

==== Defining multi-fields within multi-fields
|
|
|
|
Previously, it was possible to define a multi-field within a multi-field.
|
|
Defining chained multi-fields was deprecated in 7.3 and is now no longer
|
|
supported. To migrate the mappings, all instances of `fields` that occur within
|
|
a `fields` block should be removed, either by flattening the chained `fields`
|
|
blocks into a single level, or by switching to `copy_to` if appropriate.

[[fieldnames-enabling]]
|
|
==== Disallow use of the `enabled` setting on the `_field_names` field
|
|
|
|
The setting has been deprecated with 7.5 and is no longer supported on new indices.
|
|
Mappings for older indices will continue to work but emit a deprecation warning.
|
|
The `enabled` setting for `_field_names` should be removed from templates and mappings.
|
|
Disabling _field_names is not necessary because it no longer carries a large index overhead.
