* Incorporated review comments.
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.
* Add xpack setting deprecations to deprecation API
The deprecated settings showed up in the deprecation log file by
default, but I did not add them to the deprecation API. This commit
fixes that. Now if you use one of the deprecated basic feature
enablement settings, calling _monitoring/deprecations will inform you of
that fact.
* Remove incorrectly backported settings documents
It seems that I backported these docs to the wrong place in #56061,
in #55980, and in #56167. I hope they're in the right place now.

This commit creates a new gradle plugin to provide a separate task name
and source set for running ESIntegTestCase tests. The only project
converted to use the new plugin in this PR is server, as an example. The
remaining cases in x-pack will be handled in followups.
backport of #55896

Notes that you cannot use EQL in ES to search the values of `nested`
fields or their sub-fields. However, indices containing `nested` field
mappings are otherwise supported.
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
The following settings are now no-ops:
* xpack.flattened.enabled
* xpack.logstash.enabled
* xpack.rollup.enabled
* xpack.slm.enabled
* xpack.sql.enabled
* xpack.transform.enabled
* xpack.vectors.enabled
Since these settings no longer need to be checked, we can remove settings
parameters from a number of constructors and methods, and do so in this
commit.
We also update documentation to remove references to these settings.
Our upgrade docs don't mention the upgrade assistant, which can be
helpful when migrating across major versions. The docs also don't
mention deprecation logs, which can highlight other functionality that
may change.
This adds a related tip admonition to the upgrade docs.
This PR implements the following changes to make ML model snapshot
retention more flexible in advance of adding a UI for the feature in
an upcoming release.
- The default for `model_snapshot_retention_days` for new jobs is now
10 instead of 1
- There is a new job setting, `daily_model_snapshot_retention_after_days`,
that defaults to 1 for new jobs and `model_snapshot_retention_days`
for pre-7.8 jobs
- For days that are older than `model_snapshot_retention_days`, all
model snapshots are deleted as before
- For days that are in between `daily_model_snapshot_retention_after_days`
and `model_snapshot_retention_days` all but the first model snapshot
for that day are deleted
- The `retain` setting of model snapshots is still respected to allow
selected model snapshots to be retained indefinitely
Backport of #56125
Per #54411, we plan to handle case sensitivity via a parameter for the
EQL search API (with the possible exception of the `between` function).
This removes references and examples related to case sensitivity from
the EQL functions docs.
Previously, when the timezone was missing from the datetime string
and the pattern, UTC was used, instead of the session defined timezone.
Moreover, if a timezone was included in the datetime string and the
pattern then this timezone was used. To have a consistent behaviour
the resulting datetime will always be converted to the session defined
timezone, e.g.:
```
SELECT DATETIME_PARSE('2020-05-04 10:20:30.123 +02:00', 'HH:mm:ss dd/MM/uuuu VV') AS datetime;
```
with `time_zone` set to `-03:00` will result in
```
2020-05-04T05:20:40.123-03:00
```

* Delay warning about missing x-pack (#54265)
Currently, when monitoring is enabled in a freshly-installed cluster,
the non-master nodes log a warning message indicating that master may
not have x-pack installed. The message is often printed even when the
master does have x-pack installed but takes some time to setup the local
exporter for monitoring. This commit adds the local exporter setting
`wait_master.timeout` which defaults to 30 seconds. The setting
configures the time that the non-master nodes should wait for master to
setup monitoring. After the time elapses, they log a message to the user
about possible missing x-pack installation on master.
The logging of this warning was moved from `resolveBulk()` to
`openBulk()` since `resolveBulk()` is called only on cluster updates and
the message might not be logged until a new cluster update occurs.
Closes#40898
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
Backports #55933 to 7.x
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
* Allow Deleting Multiple Snapshots at Once (#55474)
Adds deleting multiple snapshots in one go without significantly changing the mechanics of snapshot deletes otherwise.
This change does not yet allow mixing snapshot delete and abort. Abort is still only allowed for a single snapshot delete by exact name.
* 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
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
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.

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.

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.
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 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
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.
Backport of #55716
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
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`
The example looks the same as in the previous section although it should use the
"fuzziness" parameter. This seems to be okay on 6.8 and master and was probably
only forgotten to port to 7.x branches.
This adds a validation to VSParserHelper to ensure that a field or
script or both are specified by the user. This is technically
required today already, but throws an exception much deeper
in the agg framework and has a very unintuitive error for the user
(as well as eating more resources instead of failing early)
Adds a important admonition to the EQL syntax page noting that
the equal (`==`) operator should not be used to match `text` field
values.
Relates to #52709 and #53020
Documents several parameters missing from the bulk API's response body
docs. Also moves several response-related chunks of text to the response
body section.
