In order to perform a kNN search on a `dense_vector` field, it must have
`index: true` in its mapping. This commit clarifies the error message. Before
the message was confusing, because the user likely didn't touch the `index`
parameter and might not even be aware of it.
It adds a note to the docs clarifying that when coming from 7.x, you must
explicitly update `index: true` and reindex the vectors.
Relates to #78473.
Today, a search request with PIT would fail immediately if any
associated indices or nodes are gone, which is inconsistent when
allow_partial_search_results is true.

The hidden index docs did not mention that dot-prefixed patterns default
to matching hidden indices. This PR adds a note explaining the behavior
and why it's like that.
The current `multi_match` docs contain an erroneous reference to the `combined_fields` query. This updates the reference to reference the correct query.

The searchable snapshot action mounts snapshots as indices
with a different prefix depending of the phase. This commit
tries to mention them in the docs.
Manipulating the contents of a snapshot repository is a very bad idea,
but it turns out we don't call this out in the docs anywhere. This
commit adds a warning about this.
The documentations states that if the `weight` field is missing, and no
explicit missing configuration is provided, a default value of 1 is used.
This is incorrect and does not match the implementation of the weighted
average aggregator. In this specific case the document is skipped, instead.
The change removes a node-level setting. It was accidentally placed with REST API changes as part of https://github.com/elastic/elasticsearch/issues/79162. This moves the breaking change to the cluster and node setting changes section.
Removes source-related query parameters from the update by query
and delete by query API documentation. These parameters don't return
source fields as part of the response.
Today we increase the verbosity of discovery failures after 5 minutes
without a master. Unfortunately 5 minutes is a common orchestration
timeout, so if discovery is broken then we see nodes being shut down
just before they start to emit useful logs. This commit reduces the
default timeout to 3 minutes to address that.
Internally we already kept track of whether a data stream is replicated by CCR.
It is part of the `DataStream` class. This just adds it to the xcontent serialization
of the get data stream api response class.

Add a --url option for elasticsearch-reset-password and
elasticsearch-create-enrollment-token CLI Tools ( and any tools
that would extend BaseRunAsSuperuserCommand ).
The tools use CommandLineHttpClient internally, which tries its
best to deduce the URL of the local node based on the configuration
but there are certain cases where it either fails or returns an
unwanted result. Concretely:
- CommandLineHttpClient#getDefaultURL will always return a URL with
the port set to 9200, unless otherwise explicitly set in the
configuration. When running multiple nodes on the same host,
subsequent nodes get sequential port numbers after 9200 by default
and this means that the CLI tool will always connect the first of
n nodes in a given host. Since these tools depend on a file realm
local user, requests to other nodes would fail
- When an ES node binds and listens to many addresses, there can
be the case that not all of the IP addresses are added as SANs in
the certificate that is used for TLS on the HTTP layer.
CommandLineHttpClient#getDefaultURL will pick an address based on
a preference order but that address might not be in the SANs and
thus all requests to the node would fail due to failed hostname
verification.
Manually setting `--url` to an appropriate value allows users to
overcome these edge cases.
Today we indicate that the `unassigned.reason` field in various APIs
indicates the reason why a shard is unassigned. This isn't really true,
it tells you some information about the event that caused the shard to
_become_ unassigned (or which most recently changed its routing table
entry while remaining unassigned) but tells you almost nothing about why
the shard _is now_ unassigned and how to fix it. That's what the
allocation explain API is for. This commit clarifies this point in the
docs.

Adds to the transport node stats a record of the distribution of the
times for which a transport thread was handling a message, represented
as a histogram.

You can no longer configure `xpack.searchable.snapshot.shared_cache.size` as a user setting in ESS on 7.13+ deployments. This PR removes the ESS icon from the related 8.0 breaking change for the setting.
It also clarifies the breaking change text to indicate that configuring the setting on non-frozen nodes will result in an error on startup.
