Previously, the following situation would throw an error:
* A search contains a `collapse` on a particular field.
* The search spans multiple indices, and in one index the field is mapped as a
concrete field, but in another it is a field alias.
The error occurs when we attempt to merge `CollapseTopFieldDocs` across shards.
When merging, we validate that the name of the collapse field is the same across
shards. But the name has already been resolved to the concrete field name, so it
will be different on shards where the field was mapped as an alias vs. shards
where it was a concrete field.
This PR updates the collapse field name in `CollapseTopFieldDocs` to the
original requested field, so that it will always be consistent across shards.
Note that in #32648, we already made a fix around collapsing on field aliases.
However, we didn't test this specific scenario where the field was mapped as an
alias in only one of the indices being searched.
Currently, if an updateable synonym filter is included in a multiplexer filter,
it is not reloaded via the _reload_search_analyzers because the multiplexer
itself doesn't pass on the analysis mode of the filters it contains, so its not
recognized as "updateable" in itself. Instead we can check and merge the
AnalysisMode settings of all filters in the multiplexer and use the resulting
mode (e.g. search-time only) for the multiplexer itself, thus making any synonym
filters contained in it reloadable. This, of course, will also make the
analyzers using the multiplexer be usable at search-time only.
Closes#50554
This commits makes the "init" ILM step retryable. It also adds a test
where an index is created with a non-parsable index name and then fails.
Related to #48183
strict_date_optional_time changes to have optional minute part.
It already allowed optional second and fraction of second part.
This allows parsing 2018-01-01T00+01 , 2018-01-01T00:00+01 , 2018-01-01T00:00:00+01 , 2018-01-01T00:00:00.000+01
It won't allow parsing a timezone without an hour part as this is not allowed by iso8601 spec
closes#49351
Adds a 'text analysis overview' page to the analysis topic docs.
The goals of this page are:
* Concisely summarize the analysis process while avoiding in-depth concepts, tutorials, or API examples
* Explain why analysis is important, largely through highlighting problems with full-text searches missing analysis
* Highlight how analysis can be used to improve search results
ElasticsearchException.guessRootCauses would return wrapper exception if
inner exception was not an ElasticsearchException. Fixed to never return
wrapper exceptions.
At least following APIs change root_cause.0.type as a result:
_update with bad script
_index with bad pipeline

The Analysis docs mention including a default analyzer in the index settings. However, no example snippet is included.
This adds an example snippet that users can easily copy and adjust.
This solves half of the problem in #46813 by moving the S3
tests to using the shared minio fixture so we at least have
some non-3rd-party, constantly running coverage on these tests.
This PR adds per-field metadata that can be set in the mappings and is later
returned by the field capabilities API. This metadata is completely opaque to
Elasticsearch but may be used by tools that index data in Elasticsearch to
communicate metadata about fields with tools that then search this data. A
typical example that has been requested in the past is the ability to attach
a unit to a numeric field.
In order to not bloat the cluster state, Elasticsearch requires that this
metadata be small:
- keys can't be longer than 20 chars,
- values can only be numbers or strings of no more than 50 chars - no inner
arrays or objects,
- the metadata can't have more than 5 keys in total.
Given that metadata is opaque to Elasticsearch, field capabilities don't try to
do anything smart when merging metadata about multiple indices, the union of
all field metadatas is returned.
Here is how the meta might look like in mappings:
```json
{
"properties": {
"latency": {
"type": "long",
"meta": {
"unit": "ms"
}
}
}
}
```
And then in the field capabilities response:
```json
{
"latency": {
"long": {
"searchable": true,
"aggreggatable": true,
"meta": {
"unit": [ "ms" ]
}
}
}
}
```
When there are no conflicts, values are arrays of size 1, but when there are
conflicts, Elasticsearch includes all unique values in this array, without
giving ways to know which index has which metadata value:
```json
{
"latency": {
"long": {
"searchable": true,
"aggreggatable": true,
"meta": {
"unit": [ "ms", "ns" ]
}
}
}
}
```
Closes#33267
In order to ensure that logstash and Elasticsearch are able to understand
the same patterns, this commit adapts to changes in logstash, adds a few
patterns and changes a few.
Introduce a new static setting, `gateway.auto_import_dangling_indices`, which prevents dangling indices from being automatically imported. Part of #48366.
This makes the "update-rollover-lifecycle-date" step, which is part of the
rollover action, retryable. It also adds an integration test to check the
step is retried and it eventually succeeds.

In security we currently monitor a set of files for changes:
- config/role_mapping.yml (or alternative configured path)
- config/roles.yml
- config/users
- config/users_roles
This commit prevents unnecessary reloading when the file change actually doesn't change the internal structure.

vector REST tests occasionally fail on 7.x because
we don't receive the expected response headers with deprecation warnings.
This happens as searchers were executed against all indices including
internal indices, whose shards did not produce expected warnings.
This PR ensures that searchers are executed only against expected
indices.
Closes#50716
When there several subqueries on different relations of the join field,
and only one of subqueries is using inner_hits, NPE occurs.
This PR prevents NPE error.

* Faster and Simpler GCS REST Mock
I reworked the GCS mock a little to use less copying+allocation,
log the full request body on failure to read a multi-part request
and generally be a little simpler and easy to follow to track down
the remaining issues that are causing almost daily failures from this
class's multi-part request parsing that can't be reproduced locally.
This commit adds a cliSetup command that can be used to run arbitrary
bin scripts to setup a test cluster. This is the same as what was
previously called setupCommands in cluster formation tasks.

We *very* commonly have object with ctors like:
```
public Foo(String name)
```
And then declare a bunch of setters on the object. Every aggregation
works like this, for example. This change teaches `ObjectParser` how to
build these aggregations all on its own, without any help. This'll make
it much cleaner to parse aggs, and, probably, a bunch of other things.
It'll let us remove lots of wrapping. I've used this new power for the
`avg` aggregation just to prove that it works outside of a unit test.
If an auto-refresh happens, then version_map_memory is reset to 0. By
default, the auto-refresh occurs for every second in the first 30
seconds until search becomes idle.

#43007 restructured the SQL REST API docs so they display across several pages.
This updates up a reference that assumes a single page in the "Paginating through a large response" section. It also reformats a tip for the Kibana console.

In 7.x an internal API used for validating remote cluster does not throw, see #50420 for the

Switch from a 32 bit Java hash to a 128 bit Murmur hash for
creating document IDs from by/over/partition field values.
The 32 bit Java hash was not sufficiently unique, and could
produce identical numbers for relatively common combinations
of by/partition field values such as L018/128 and L017/228.
Fixes#50613
The end offset of a tokenizer is supposed to point one past the
end of the input, not to the end character of the input. The
ml_classic tokenizer was erroneously doing the latter.
This test seems to be bogus as it was confusing a nominal execution time with a
delay (i.e. an elapsed time). This commit reworks the test to address this.
Fixes#50650
With the rewrite of the percolator's QueryAnalyzer to use lucene's QueryVisitor API,
term queries that are direct children of a boolean query are handled separately from
other children. This works fine for conjunctions, but for disjunctions we need to
treat the extracted terms from these direct descendents along with extractions from
more deeply nested children to ensure that minimum-should-match requirements
are met correctly.
This commit changes the logic in QueryAnalyzer#getResult() to bundle child term
results with all other results before handling them.
Fixes#50305
A failure of a recovering shard can race with a new allocation of the shard, and cause the new
allocation to be failed as well. This can result in a shard being marked as initializing in the cluster
state, but not exist on the node anymore.
Closes#50508
* Add aditional logging for ILM history store tests (#50624)
These tests use the same index name, making it hard to read logs when
diagnosing the failures. Additionally more information about the current
state of the index could be retrieved when failing.
This changes these two things in the hope of capturing more data about
why this fails on some CI nodes but not others.

This change removes a no longer used method, `fromByte`, in
IndicesOptions. This method was necessary for backwards compatibility
with versions prior to 6.4.0 and was used when talking to those
versions. However, the minimum wire compatibility version has changed
and we no longer use this code.
Backport of #50665
This drops all remaining references to `BaseRestHandler.logger` which
has been deprecated for something like a year now. I replaced all of the
references with locally declared loggers which is so much less spooky
action at a distance to me.
Sharing a random generator may cause test failures as non-threadsafe random generators are periodically utilized in tests (see: https://github.com/elastic/elasticsearch/issues/50651)
This change constructs a calls `Randomness.get()` within the `bulkIndexWithRetry` method so that the returned `Random` object is only used in a single thread. Before, the member variable could have been used between threads, which caused test failures.
* [ML][Inference] lang_ident model (#50292)
This PR contains a java port of Google's CLD3 compact NN model https://github.com/google/cld3
The ported model is formatted to fit within our inference model formatting and stored as a resource in the `:xpack:ml:` plugin and is under basic license.
The model is broken up into two major parts:
- Preprocessing through the custom embedding (based on CLD3's embedding layer)
- Pushing the embedded text through the two layers of fully connected shallow NN.
Main differences between this port and CLD3:
- We take advantage of Java's internal Unicode handling where possible (i.e. codepoints, characters, decoders, etc.)
- We do not trim down input text by removing duplicated tokens
- We do not encode doubles/floats as longs/integers.
