The documentation currently tells users to use `doc['event_date'].value.getMillis` to access
milliseconds in a date. It turns out the way it works is `doc['event_date'].value.millis`. This
change corrects this and gives a hint at how other date related methods work.
The fix in #33757 introduces some workaround since FilterCodecReader didn't
support unwrapping. This cuts over to a more elegant fix to access the readers
segment infos.
Previously multiple comma separated lists of options where not
recognized correctly which resulted in only the last of them
to be taked into account, e.g.:
For the following query:
SELECT * FROM test WHERE QUERY('search', 'default_field=foo', 'default_operator=and')"
only the `default_operator=and` was finally passed to the ES query.
Fixes: #32602
It is not obvious that a filesystem-level backup may capture an inconsistent
set of files that may fail on restore, or (worse) succeed having silently
discarded some data. This change spells the out, and reorganises the first page
or so of the snapshot/restore docs to make this warning fit more nicely.
This commit changes the random_score function to use the global docID of the document
rather than the segment docID to generate random scores. As a result documents that have
the same segment docID within the shard will generate different scores.
Add minimal sanity checks to custom/scripted similarities.
Lucene 8 introduced more constraints on similarities, in particular:
- scores must not be negative,
- scores must not decrease when term freq increases,
- scores must not increase when norm (interpreted as an unsigned long)
increases.
We can't check every single case, but could at least run some sanity checks.

* Profiler: Don’t profile NEXTDOC for ConstantScoreQuery.
A ConstantScore query will return the iterator of its inner query.
However, when profiling, the constant score query is wrapped separately
from its inner query, which distorts the times emitted by the profiler.
Return the iterator directly in such a case.
Closes#23430
Instead of having one constructor that accepts all arguments, all parameters
should be provided via setters. Only leader and follower index are required
arguments. This makes using this class in tests and transport client easier.
DAYNAME and MONTHNAME functions tests will be skipped if the right JVM parameter (-Djava.locale.providers=COMPAT) is not used in unit testing environment
* TESTS: Set SO_LINGER = 0 for MockNioTransport
* Prevents lingering sockets in TIME_WAIT piling up during test runs and leading to port collisions that manifest as timeouts
* Fixes#32552
Gradle can sometimes emit mixed log lines due to how we spawn things in
separate processes. This commit changes the jarhell integ test to only
look for the exception and message, instead of including the outer part
about the exception in thread main.

The change in #27500 introduces this regression that causes `_get` and `_term_vector`
actions to run on the network thread if the realtime flag is set.
This fixes the issue by delegating to the super method forking on the corresponding threadpool.
We use similar / same concepts in SerachTransportService and HandledTransportAction but both
duplicate the efforts with slightly different implementation details. This streamlines
sending responses / exceptions back to a channel in an ActionListener with appropriate logging.
Make sure that all java files have a package declaration and that all of
the package declarations line up with the directory structure. This
would have caught the bug that I caused in
190ea9a6de and fixed in
b6d68bd805.
The original statement "Runs a match_phrase query on each field and combines the _score from each field." for the phrase type is a but misleading. The phrase type behaves like the best_fields type and does not combine the scores of each fields.
In #33241 we moved the file-based discovery functionality to core
Elasticsearch, but preserved the `discovery-file` plugin, and support for the
existing location of the `unicast_hosts.txt` file, for BWC reasons. This commit
completes the removal of this plugin.
New plugin for annotated_text field type.
Largely a copy of `text` field type but adds ability to include markdown-like syntax in the text.
The “AnnotatedText” class parses text+markup and converts into plain text and AnnotationTokens.
The annotation token values are injected unchanged alongside the regular text tokens to provide a
form of additional indexed overlay useful in positional searches and highlighting.
Annotated_text fields do not support fielddata as we want to phase this out.
Also includes a new "annotated" highlighter type that retains annotations and merges in search
hits as additional annotation markup.
Closes#29467
Currently a watch execution results in one bulk request, when the
triggered watches are written into the that index, that need to be
executed. However the update of the watch status, the creation of the
watch history entry as well as the deletion of the triggered watches
index are all single document operations.
This can have quite a negative impact, once you are executing a lot of
watches, as each execution results in 4 documents writes, three of them
being single document actions.
This commit switches to a bulk processor instead of a single document
action for writing watch history entries and deleting triggered watch
entries. However the defaults are to run synchronous as before because
the number of concurrent requests is set to 0. This also fixes a bug,
where the deletion of the triggered watch entry was done asynchronously.
However if you have a high number of watches being executed, you can
configure watcher to delete the triggered watches entries as well as
writing the watch history entries via bulk requests.
The triggered watches deletions should still happen in a timely manner,
where as the history entries might actually be bound by size as one
entry can easily have 20kb.
The following settings have been added:
- xpack.watcher.bulk.actions (default 1)
- xpack.watcher.bulk.concurrent_requests (default 0)
- xpack.watcher.bulk.flush_interval (default 1s)
- xpack.watcher.bulk.size (default 1mb)
The drawback of this is of course, that on a node outage you might end
up with watch history entries not being written or watches needing to be
executing again because they have not been deleted from the triggered
watches index. The window of these two cases increases configuring the bulk processor to wait to reach certain thresholds.
The following stats are being kept track of:
1) The total number of times that auto following a leader index succeed.
2) The total number of times that auto following a leader index failed.
3) The total number of times that fetching a remote cluster state failed.
4) The most recent 256 auto follow failures per auto leader index
(e.g. create_and_follow api call fails) or cluster alias
(e.g. fetching remote cluster state fails).
Each auto follow run now produces a result that is being used to update
the stats being kept track of in AutoFollowCoordinator.

* MINOR: Drop Redundant Ctx. Check in ScriptService
* This check is completely redundant, the expression script
engine will throw anyway (and with a similar message) for
those contexts that it cannot compile. Moreover, the update context
is not the only context that is not suported by the expression engine
at this point so handling the update context separately here makes
no sense.

This PR removes fields that are not actually used by the Monitoring UI. This will greatly simplify the eventual migration to using Metricbeat for monitoring Elasticsearch (see https://github.com/elastic/beats/pull/8260#discussion_r215885868 for more context and discussion around removing these fields from ES collection).
This commit changes the sanity check which ensures the test task was
properly replaced with randomized testing to have a per project check,
isntead of a global one. The previous global check assumed all test
tasks within the root project and below should be randomized testing,
but that is not the case for a multi project in which only one project
is an elasticsearch plugin. While the new check is not able to emit all
of the failed replacements in one error message, the efficacy of the
check remains.
* [CCR] Do not unnecessarily wrap fetch exception in a ElasticSearch exception and
properly map fetch_exception.exception field as object.
The extra caused by level is not necessary here:
```
"fetch_exceptions": [
{
"from_seq_no": 1,
"retries": 106,
"exception": {
"type": "exception",
"reason": "[index1] IndexNotFoundException[no such index]",
"caused_by": {
"type": "index_not_found_exception",
"reason": "no such index",
"index_uuid": "_na_",
"index": "index1"
}
}
}
],
```
When a leader index is created, it may not have a mapping yet.
Currently if you follow such an index the shard follow tasks fail with
NoSuchElementException, because they expect a single mapping.
This commit fixes that, by allowing that a leader index does not yet have
a mapping.
We can't rely on the leaf reader ordinal in a wrapped reader since
it might not correspond to the ordinal in the SegmentInfos for it's
SegmentCommitInfo.
