=== Index API changes
|
|
|
|
|
|
|
|
|
|
==== Index aliases
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Fields used in alias filters no longer have to exist in the mapping at alias
|
|
|
|
|
creation time. Previously, alias filters were parsed at alias creation time
|
|
|
|
|
and the parsed form was cached in memory. Now, alias filters are parsed at
|
|
|
|
|
request time and the fields in filters are resolved from the current mapping.
|
|
|
|
|
|
|
|
|
|
This also means that index aliases now support `has_parent` and `has_child`
|
|
|
|
|
queries.
|
|
|
|
|
|
|
|
|
|
The <<alias-retrieving, GET alias api>> will now throw an exception if no
|
|
|
|
|
matching aliases are found. This change brings the defaults for this API in
|
|
|
|
|
line with the other Indices APIs. The <<multi-index>> options can be used on a
|
|
|
|
|
request to change this behavior.
|
|
|
|
|
|
|
|
|
|
==== File based index templates
|
|
|
|
|
|
|
|
|
|
Index templates can no longer be configured on disk. Use the
|
|
|
|
|
<<indices-templates,`_template`>> API instead.
|
|
|
|
|
|
|
|
|
|
==== Analyze API changes
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
The Analyze API now returns the the `position` of the first token as `0`
|
|
|
|
|
instead of `1`.
|
|
|
|
|
|
|
|
|
|
The `prefer_local` parameter has been removed. The `_analyze` API is a light
|
|
|
|
|
operation and the caller shouldn't be concerned about whether it executes on
|
|
|
|
|
the node that receives the request or another node.
|
|
|
|
|
|
|
|
|
|
The `text()` method on `AnalyzeRequest` now returns `String[]` instead of
|
|
|
|
|
`String`.
|
|
|
|
|
|
|
|
|
|
==== Removed `id_cache` from clear cache api
|
|
|
|
|
|
|
|
|
|
The <<indices-clearcache,clear cache>> API no longer supports the `id_cache`
|
|
|
|
|
option. Instead, use the `fielddata` option to clear the cache for the
|
|
|
|
|
`_parent` field.
|
|
|
|
