This also fixes an issue where a `null` priority was treated as below a 0 priority. `null` is now
treated as 0 priority when it comes to comparing V2 templates.
Relates to #53101
It's possible for a constant_keyword to have a 'null' value before any documents
are seen that contain a value for the field. In this case, no documents have a
value for the field, and 'exists' queries should return no documents.
Makes the following changes to the `porter_stem` token filter docs:
* Rewrites description and adds a Lucene link
* Adds detailed analyze example
* Adds an analyzer example
Implements value_count and avg aggregations over Histogram fields as discussed in #53285
- value_count returns the sum of all counts array of the histograms
- avg computes a weighted average of the values array of the histogram by multiplying each value with its associated element in the counts array
* Make xpack.monitoring.enabled setting a no-op
This commit turns xpack.monitoring.enabled into a no-op. Mostly, this involved
removing the setting from the setup for integration tests. Monitoring may
introduce some complexity for test setup and teardown, so we should keep an eye
out for turbulence and failures
* Docs for making deprecated setting a no-op
Adds a concise list of EQL advantages, based on the "EQL Advantages"
section in the [EQL for the masses][0] blog post.
The intent is to inform users how EQL could benefit at a high level.

I see occasional confusion about the explanations emitted by the same-shard
allocation decider, particularly amongst new users setting up a single-node
cluster and trying to determine why their cluster has `yellow` health. For
example:
the shard cannot be allocated to the same node on which a copy of the shard
already exists
This is technically correct but it's quite a complicated sentence. Also, by
starting with "the shard cannot be allocated" it makes it sound like this is
the problem, whereas in fact this message is a good thing and users should
typically focus their attention elsewhere.
This commit simplifies the wording of these messages and makes them sound more
positive, for example:
a copy of this shard is already allocated to this node
* Expose agg usage in Feature Usage API
Counts usage of the aggs and exposes them on the _nodes/usage/.
Closes#53746
* Refactor to include non value sources aggregations
* Fix reported values source type for parent and children aggs
* Refactor SearchModule constructor
* Fix subtype in TTest and IPRanges
* Fix more subtypes in aggs that don't register themselves
* Fix doc tests
* Fix docs
* Fix ScriptedMetricAggregatorTests
* Fix compilation issues after merge
* Fix merge fallout
* This gets stale quickly...
* Address review comments
* Fix tests that were missing proper agg registration in the search module
* Fix ScriptedMetricAggregatorTests
* Address review comments

Removes an example from the "Document counts are approximate" section of the
terms agg documentation.
As #52377 details, the example was no longer accurate in 7.x or 6.8. Document
counts were more precise than the example presented.
We've opened issue #56025 to discuss re-adding an example later.

* Remove NO_ILM ml index templates
* Remove unneeded setting from test setup
* Inline variable definitions for ML templates
* Use identical parameter names in templates
* New ILM/watcher setting falls back to old setting

Makes the following changes to the `kstem` token filter docs:
* Rewrite description and adds a Lucene work
* Adds detailed analyze example
* Adds an analyzer example
This commit adds the initial document for version two index templates. Since these are intended to
be used in favor of V1 index templates, this re-uses the anchors for index templates to point to the
V2 APIs, renaming the V1 template docs' anchors (this was a suggestion from the docs team).
There is more documentation that can be written, but this is a start.
Relates to #53101
This adds support for V2 index templates to the cat templates API. It uses the `order` field as
priority in order not to break compatibility, while adding the `composed_of` field to show component
templates that are used from an index template.
Relates to #53101
Warn about potential performance impact when a large number of fields
is used with query string query and no default field.
Re-adds content from #35570.
That content was erroneously removed in #45296.

This has no practical impact on users since frozen indices are the only
throttled indices today. However this has an impact on upcoming features
that would use search throttling.
Filtering out throttled indices made sense a couple years ago, but as
we're now improving support for slow requests with `_async_search` and
exploring ways to reduce storage costs, this feature has most likely
become a trap, that we'd like to not have with upcoming features that
would use search throttling.
Relates #54058
The disk decider had special handling for the single data node case,
allowing any allocation (skipping watermark checks) for such clusters.
This special handling can now be avoided via a setting.
The Lucene `preserve_original` setting is currently not supported in the `edge_ngram`
token filter. This change adds it with a default value of `false`.
Closes#55767
In 7.0, we began formatting `docvalue_fields` by default using each field's
mapping definition. To ease the transition from 6.x, we added the format
option `use_field_mapping`. This parameter was deprecated in 7.0, and we can
remove it in 8.0.

The failed_category_count statistic records the number of times
categorization wanted to create a new category but couldn't
because the job had reached its model_memory_limit.

Makes the following changes to the `stemmer` token filter docs:
* Adds detailed analyze example
* Rewrites parameter definitions
* Adds custom analyzer example
* Adds a `language` value for the `estonian` stemmer
* Reorders the `language` values to show recommended algorithms first,
followed by other values alphabetically
The use of node filters for excluding nodes from the voting configuration was
deprecated in #50836; this commit removes support for node filters in this API.
Closes#47990
Adds conceptual documentation for stemming, including:
* An overview of why stemming is helpful in search
* Algorithmic vs. dictionary stemming
* Token filters used to control stemming, such as `stemmer_override`, `keyword_marker`, and `conditional`
