Default headers are now read-only fallbacks if the key is actually not in
the headers map. That way we never serialize them across the wire and also never
prevent them from being overwritten.
This has caused some test failures lately especially on window (which is likely caused
by the rather bad performance of the windows test machines).
See one failure here:
http://build-us-00.elastic.co/job/es_core_master_window-2008/2934/
This fix has now also a unittest that tests this issue separately.
* Cleaned up MapperService#searchFilter(...) and moved it DefaultSearchContext, since it that class was the only user. As part of the cleanup percolate query documents are no longer excluded from the search response.
* Removed resolveClosestNestedObjectMapper(...) method as it was no longer used.
* Removed DocumentTypeListener infrastructure. Before it was used by the percolator and parent/child, but these features no longer use it.
Closes#15924
Adding the ability to parse from xContent to the rescore builder.
Also making RescoreBuilder an interface and renaming the current
base builder that encapsulates the `window_size` setting the the
concrete rescorer implementation to RescoreBaseBuilder.
* Remove remaining 1.x bwc logic.
* Stop storing stored fields and indexed terms. The _parent field's only purpose is to support joins between parent and child type and only storing doc values is sufficient.
* In the mapping the parent field mapper is now known under '{parent}#{child}' key, because this is the field the parent/child join uses too.
* Added new sub fetch phase to lookup that _parent field from doc values field if that is required (before this was fetched from stored _parent field)
* Removed the ability to query directly on `_parent` in the query dsl. Instead the `{parent}#{child}` field should be used. Under the hood a doc values query is used instead of a term query, because only doc values fields are stored now.
* Added a new `parent_id` query to easily query child documents with a specific parent id without having to know what join field to use
* Also in aggregations `_parent` field can't be used any more and `{parent}#{child}` field name should be used instead to aggregate directly on the _parent join field.
