Changes the type of the version parameter in `IngestDocument` from
`Long` to `long` and moves it to the third argument, so all required
values occur before nullable arguments.
The `IngestService` expects a non-null version for a document and will
throw an `NullPointerException` if one is not provided.

Adds measures of the total size of all mappings and the total number of
fields in the cluster (both before and after deduplication).

The current docs mention that Elasticsearch indexes prefixes between 2 and 5 characters in a separate field. 2 and 5 are default values, and the size of the prefixes indexed depend on the configuration settings.

This change tries to make it easier to find kNN with filtering in the docs:
* Mention filtering support in the kNN API description
* In kNN tutorial, link to the kNN search API page more prominently
This guidance does not apply any longer.
The overhead per shard has been significantly reduced in recent versions
and removed rule of thumb will be too pessimistic in many if not
most cases and might be too optimistic in other specific ones.
=> Replace guidance with rule of thumb per field count on data nodes and
rule of thumb by index count (which is far more relevant nowadays than
shards) for master nodes.

This adds troubleshooting documentation for the case when the ShardsAvailabilityHealthIndicatorService
reports that there are not enough nodes in the data tier (user action "increase_node_capacity_for_allocations" or
"increase_tier_capacity_for_allocations_". This covers both the cloud and self-managed environments. For
cloud we first recommend increasing the number of availability zones (because you cannot directly add nodes), and
decreasing index.number_of_replicas if that is not possible. For self-managed, we first recommend adding nodes,
and decreasing index.number_of_replicas if that is not possible.
This removes "data streams" from the docs for the `index`, `delete`,
and `update` actions because data streams only support the `update`
action.
Closes#87231
Add cluster mapping stats for indexed dense_vectors
Currently _cluster/stats mapping section displays all mapping types
along with their count. In 8.0 we introduced indexed dense_vector
types, and we would like to collect more enhanced stats on them:
- number of indexed dense_vector fields
- sum of dims across all indexed dense_vector fields
This allows to differentiate how indexed dense_vector types are
used as opposed to unindexed dense_vector types.
Add `ignore_missing_pipeline` option to `pipeline` processor. This
controls whether the `pipeline` processor should fail with an error if
no pipeline with a name specified in the `name` option exists.
This enhancement is useful to setup a pipeline infrastructure that
lazily adds extension points for overwrites. So that for specific
cluster setups custom pre-processing can be added at a later point in
time.

In #85074 we added docs on discovery troubleshooting that really only
talked about troubleshooting master elections. There's also the case
where the master is elected fine but some other node can't join it. This
commit adds troubleshooting docs about that too.

Including extracting static content from migration/index, so the template would be as light as possible.
The reason for this work is because the gradle task `generateReleaseNotes` was not correctly adding new links and imports to the migrations/index and that caused documentation to fail building for 8.3.0.
Back when we introduced the fields parameter to the search API, it could only fetch values from _source, hence
the corresponding sub-fetch phase fails early whenever _source is disabled. Today though runtime fields can
be retrieved from a separate value fetcher that reads from fielddata, and metadata fields can be retrieved
from stored fields. These two scenarios currently throw an unnecessary error whenever _source is disabled.
This commit removes the check for disabled _source, so that runtime fields and metadata fields can be retrieved even when _source is disabled. Fields that need to be loaded from _source are simply skipped whenever _source is disabled, similar to when a field is not found in _source.
Closes#87072
Add support for
allow_partial_search_results = true/false
command in SQL CLI.
If true, returns partial results if there are shard request timeouts or shard failures.
If false, returns an error with no partial results.
This adds an example of the precision loss for `double`, `float`, and
`half_float` numbers that we can link folks to when explaining what
happened to their numbers. You can link directly to it with something
like:
```
/guide/number.html#floating_point
```
* Adding Getting Help section
Add getting help section in the troubleshooting guide to be pointed by health API when issues are too complicated to be addressed.
This is taken from https://www.elastic.co/guide/en/cloud/current/ec-get-help.html, someone might want to elaborate it a bit more?
* Fix broken partintro, modify headings, and update wording

The get settings api has accepts the expand_wildcards option. The docs
state the default value is `all`, but it is actually now `open` (which
does not include hidden or closed indices by default). This commit
changes the docs to match the existing behavior.
This adds a troubleshooting doc for indices that mix index filtering allocation
with data tiers routing.

This replaces the implementation of the categorize_text aggregation
with the new algorithm that was added in #80867. The new algorithm
works in the same way as the ML C++ code used for categorization jobs
(and now includes the fixes of elastic/ml-cpp#2277).
The docs are updated to reflect the workings of the new implementation.
