This feature adds a new `fields` parameter to the search request, which
consults both the document `_source` and the mappings to fetch fields in a
consistent way. The PR merges the `field-retrieval` feature branch.
Addresses #49028 and #55363.
Moves the search sort docs from the deprecated 'Request Body Search'
page to a new subpage of 'Run a search'.
No substantive changes were made to the content.
Adds a new `my-index-00001` REST test for docs snippets.
This test can serve as a lightweight replacement for
our existing `twitter` REST tests.
The new dataset is:
* Based on Apache logs, which is better aligned with Elastic use cases
* Compliant with ECS
* Similar to the existing `twitter` data set, containing the same field data types
* Lightweight, which should keep existing test runtimes roughly the same
Also updates the search API reference docs to use the new test.
Moves the highlighting docs from the deprecated 'Request Body Search'
chapter to the new subpage of the 'Run a search chapter' section.
No substantive changes were made to the content.
Introduces a new method on `MappedFieldType` to return a family type name which defaults to the field type.
Changes `wildcard` and `constant_keyword` field types to return `keyword` for field capabilities.

Changes:
* Adds additional examples to the `Search a data stream` section of
`Use a data stream`
* Updates existing search docs to make them aware of data streams
This change allows to use an `index_filter` in the
field capabilities API. Indices are filtered from
the response if the provided query rewrites to `match_none`
on every shard:
````
GET metrics-*
{
"index_filter": {
"bool": {
"must": [
"range": {
"@timestamp": {
"gt": "2019"
}
}
}
}
}
````
The filtering is done on a best-effort basis, it uses the can match phase
to rewrite queries to `match_none` instead of fully executing the request.
The first shard that can match the filter is used to create the field
capabilities response for the entire index.
Closes#56195

Cleans up the reference documentation for the following
search API parameters:
* `_source` query parameter
* `_source_excludes` query parameter
* `_source_includes` query parameter
* `_source` request body parameter
* `hits._source` response property
Moves the source filtering example snippets form the "Request body
search" API docs page to the "Return fields in a search" section of the
"Run a search" page.
This PR adds a section to the new 'run a search' reference that explains
the options for returning fields. Previously each option was only listed as a
separate request parameter and it was hard to know what was available.
Several APIs support options that can be specified as a query parameter or a
request body parameter.
Currently, this is documented using notes, which can get rather lengthy. This
replaces those multiple notes with a single note and a footnote.
Generally we don't advocate for using `stored_fields`, and we're interested in
eventually removing the need for this parameter. So it's best to avoid using
stored fields in our docs examples when it's not actually necessary.
Individual changes:
* Avoid using 'stored_fields' in our docs.
* When defining script fields in top-hits, de-emphasize stored fields.
Reworks the `from / size` content to `Paginate search results`.
Moves those docs from the request body search API page (slated for
deletion) to the `Run a search` tutorial docs.
Also adds some notes to the `from` and `size` param docs.

**Goal**
Create a top-level search section. This will let us clean up our search
API reference docs, particularly content from [`Request body search`][0].
**Changes**
* Creates a top-level `Search your data` page. This page is designed to
house concept and tutorial docs related to search.
* Creates a `Run a search` page under `Search your data`. For now, This
contains a basic search tutorial. The goal is to add content from
[`Request body search`][0] to this in the future.
* Relocates `Long-running searches` and `Search across clusters` under
`Search your data`. Increments several headings in that content.
* Reorders the top-level TOC to move `Search your data` higher. Also
moves the `Query DSL`, `EQL`, and `SQL access` chapters immediately
after.

This saves memory when running numeric significant terms which are not
at the top level by merging its collection into numeric terms and relying
on the optimization that we made in #55873.
This adds a few things to the `breakdown` of the profiler:
* `histogram` aggregations now contain `total_buckets` which is the
count of buckets that they collected. This could be useful when
debugging a histogram inside of another bucketing agg that is fairly
selective.
* All bucketing aggs that can delay their sub-aggregations will now add
a list of delayed sub-aggregations. This is useful because we
sometimes have fairly involved logic around which sub-aggregations get
delayed and this will save you from having to guess.
* Aggregtations wrapped in the `MultiBucketAggregatorWrapper` can't
accurately add anything to the breakdown. Instead they the wrapper
adds a marker entry `"multi_bucket_aggregator_wrapper": true` so we
can be quickly pick out such aggregations when debugging.
It also fixes a bug where `_count` breakdown entries were contributing
to the overall `time_in_nanos`. They didn't add a large amount of time
so it is unlikely that this caused a big problem, but I was there.
To support the arbitrary breakdown data this reworks the profiler so
that the `breakdown` can contain any data that is supported by
`StreamOutput#writeGenericValue(Object)` and
`XContentBuilder#value(Object)`.
Changes:
* Moves the document request body parameters for the search API
from the Request body search page to the Search API reference page.
* Relocates a search request body example from the Request body search
page to the Search API reference page.
* Adds a note to any duplicated query and request body parameters.
This is a backport of #55884 with redirects removed.
Changes:
* Adds an abbreviated title for the search API page.
* Removes the following invalid query parameters:
* `analyzer`
* `analyze_wildcard`
* `default_operator`
* `df`
* `lenient`
* `suggest_mode`
* `suggest_size`
* Replaces the URI search page's query parameter docs with a xref
* Updates the headings of several examples
