This commit, built on top of #51708, allows to modify shard search requests based on informations collected on other shards. It is intended to speed up sorted queries on time-based indices. For queries that are only interested in the top documents.
This change will rewrite the shard queries to match none if the bottom sort value computed in prior shards is better than all values in the shard.
For queries that mix top documents and aggregations this change will reset the size of the top documents to 0 instead of rewriting to match none.
This means that we don't need to keep a search context open for this shard since we know in advance that it doesn't contain any competitive hit.
The highlighting phase for percolator queries currently uses some custom query
traversal logic to find all instances of PercolatorQuery in the query tree for the
current search context. This commit converts things to instead use a QueryVisitor,
which future-proofs us against new wrapper queries or queries from custom
plugins that the percolator module doesn't know about.
Some clients have problems running this test as a numeric key is treated like an array index by default.
We can work around this by renaming the aggregation key to not be a numeric.
Sometimes we want to deprecate and remove a ParseField entirely, without replacement;
for example, the various places where we specify a _type field in 7x. Currently we can
tell users only that a particular field name should not be used, and that another name should
be used in its place. This commit adds the ability to say that a field should not be used at
all.
The introduction of the ExitableDirectoryReader showed increase of
latencies for range queries using pointvalues.
Check for cancellation every 1024 docs instead of every 15 to lower
the impact of the check in query's performance.

(cherry picked from commit 6b5fc35e4458e60a7ca5822584ec6a60562f2c01)
There is an assertion in ReloadAnalyzersResponse.merge that compares index names
of merged responses that was falsely using object equality instead of
String.equals(). In the past this didn't seem to matter but with changes in the
test setup we started to see failures. Correcting this and also simplifying test
a bit to be able to run it repeatedly if needed.
Closes#53443
It is useful to be able to delay state recovery until enough data nodes have
joined the cluster, since this gives the shard allocator a decent opportunity
to re-use as much existing data as possible. However we also have the option to
delay state recovery until a certain number of master-eligible nodes have
joined, and this is unnecessary: we require a majority of master-eligible nodes
for state recovery, and there is no advantage in waiting for more.
This commit deprecates the unnecessary settings in preparation for their
removal.

changes the output format of preview regarding deduced mappings and enhances
it to return all the details about auto-index creation. This allows the user
to customize the index creation. Using HLRC you can create a index request
from the output of the response.

* Add REST API for ComponentTemplate CRUD
This adds the Put/Get/DeleteComponentTemplate APIs that allow inserting, retrieving, and removing
ComponentTemplateMetadata into the cluster state metadata.
These APIs are currently only available behind a feature flag system property -
`es.itv2_feature_flag_registered`.

The multiline regex rule used to detect docs code snippets greater than
76 characters in length has considerable cost to. For the high level
rest client project alone, this was taking upwards of 3 minutes. This
commit updates the rule regex pattern to use non-greedy matching when
appropriate which results in a lot fewer backtracks and about a 70%
reduction in execution time on the high level rest client module.
This commit adjusts a `deprecation[...]` message in the docs since such
messages must be on a single line. It also moves this message to the start of
the description of the deprecated setting as is the case with other such
messages.
Password changes are only allowed when the user is currently
authenticated by a realm (that permits the password to be changed)
and not when authenticated by a bearer token or an API key.
The current implicit behaviour is that when an API keys is used to create another API key,
the child key is created without any privilege. This implicit behaviour is surprising and is
a source of confusion for users.
This change makes that behaviour explicit.
If security was disabled (explicitly), then the SecurityContext would
be null, but the set_security_user processor was still registered.
Attempting to define a pipeline that used that processor would fail
with an (intentional) NPE. This behaviour, introduced in #52032, is a
regression from previous releases where the pipeline was allowed, but
was no usable.
This change restores the previous behaviour (with a new warning).
Backport of: #52691
This commit adds internalClusterTest in xpack core to run as part of
check. This was accidentally removed in a refactoring. Other xpack
modules already do this, but core was left out. This commit also mutes 2
tests that currently fail.

The logger usage check uses its own version of ASM to inspect class
files for logging usages. Master was updated to support java 11
compilation in #40754. However, 7.x still used ASM 5, which could not
read newer java bytecode versions. This commit bumps ASM in 7.x used in
the logger usage check.
closes#52408
Today it can happen that a transport message fails to send (for example,
because a transport interceptor rejects the request). In this case, the
response handler is never invoked, which can lead to necessary cleanups
not being performed. There are two ways to handle this. One is to expect
every callsite that sends a message to try/catch these exceptions and
handle them appropriately. The other is merely to invoke the response
handler to handle the exception, which is already equipped to handle
transport exceptions.
* Submit async search to work only with POST (#53368)
Currently the submit async search API can be called using both GET and POST at REST, but given that it submits a call and creates internal state, POST should be the only allowed method.
* Refine SearchProgressListener internal API (#53373)
The following cumulative improvements have been made:
- rename `onReduce` and `notifyReduce` to `onFinalReduce` and `notifyFinalReduce`
- add unit test for `SearchShard`
- on* methods in `SearchProgressListener` shouldn't need to be public as they should never be called directly, they only need to be overridden hence they can be made protected. They are actually called directly from a test which required some adapting, like making `AsyncSearchTask.Listener` class package private instead of private
- Instead of overriding `getProgressListener` in `AsyncSearchTask`, as it feels weird to override a getter method, added a specific method that allows to retrieve the Listener directly without needing to cast it. Made the getter and setter for the listener final in the base class.
- rename `SearchProgressListener#searchShards` methods to `buildSearchShards` and make it static given that it accesses no instance members
- make `SearchShard` and `SearchShardTask` classes final
* Move async search yaml tests to x-pack yaml test folder (#53537)
The yaml tests for async search currently sit in its qa folder. There is no reason though for them to live in a separate folder as they don't require particular setup. This commit moves them to the main folder together with the other x-pack yaml tests so that they will be run by the client test runners too.
* [DOCS] Add temporary redirect for async-search (#53454)
The following API spec files contain a link to a not-yet-created
async search docs page:
* [async_search.delete.json][0]
* [async_search.get.json][1]
* [async_search.submit.json][2]
The Elaticsearch-js client uses these spec files to create their docs.
This created a broken link in the Elaticsearch-js docs, which has broken
the docs build.
This PR adds a temporary redirect for the docs page. This redirect
should be removed when the actual API docs are added.

I broke sorting aggregations by `doc_count` in #51271 by mixing up true
and false. This flips that comparison and adds a few tests to double
check that we don't so this again.
This begins to clean up how `PipelineAggregator`s and executed.
Previously, we would create the `PipelineAggregator`s on the data nodes
and embed them in the aggregation tree. When it came time to execute the
pipeline aggregation we'd use the `PipelineAggregator`s that were on the
first shard's results. This is inefficient because:
1. The data node needs to make the `PipelineAggregator` only to
serialize it and then throw it away.
2. The coordinating node needs to deserialize all of the
`PipelineAggregator`s even though it only needs one of them.
3. You end up with many `PipelineAggregator` instances when you only
really *need* one per pipeline.
4. `PipelineAggregator` needs to implement serialization.
This begins to undo these by building the `PipelineAggregator`s directly
on the coordinating node and using those instead of the
`PipelineAggregator`s in the aggregtion tree. In a follow up change
we'll stop serializing the `PipelineAggregator`s to node versions that
support this behavior. And, one day, we'll be able to remove
`PipelineAggregator` from the aggregation result tree entirely.
Importantly, this doesn't change how pipeline aggregations are declared
or parsed or requested. They are still part of the `AggregationBuilder`
tree because *that* makes sense.
