* [Geo] Expose BKDBackedGeoShapes as new VECTOR strategy
This commit exposes lucene's LatLonShape field as a new
strategy in GeoShapeFieldMapper. To use the new indexing
approach, strategy should be set to "vector" in the
geo_shape field mapper. If the tree parameter is set
the mapper will throw an IAE. Note the following:
When using vector strategy:
* geo_shape query does not support querying by POINT,
MULTIPOINT, or GEOMETRYCOLLECTION.
* LINESTRING and MULTILINESTRING queries do not support
WITHIN relation.
* CONTAINS relation is not supported.
* The tree, precision, tree_levels, distance_error_pct,
and points_only parameters will not throw an exception
but they have no effect and will be marked as
deprecated..
All other features are supported.
* revert change to PercolatorFieldMapper
* fix ExistsQuery for geo_shape vector strategy
* add deprecation logging for tree, precision, tree_levels, distance_error_pct, and points_only
* initial update to geoshape docs, including mapping migration updates
* initial support for GeoCollection queries
* fix docs and javadoc errors
* clean up geocollection queries
* set deprecated mapping tests to NOTCONSOLE
* fix geo-shape mapper asciidoc mapping and test warnings
* add support for point queries using LatLonShapeBoundingBoxQuery
* update GeoShapeQueryBuilderTests to include POINT queries for VECTOR strategy. Other comment cleanups
* add lucene geometry build testing to ShapeBuilder tests
* remove deprecated prefix tree mapping from geo-shape.asciidoc
* refactor GeoShapeFieldMapper into LegacyGeoShapeFieldMapper and GeoShapeFieldMapper
Both classes derive from BaseGeoShapeFieldMapper that provides shared parameters:
coerce, ignoreMalformed, ignore_z_value, orientation.
* update docs to remove vector strategy
* fix GeometryCollectionBuilder#buildLucene to return the object created by the shape builder
* fix LineLength failure in GeoJsonShapeParserTests
* ShapeMapper refactor changes from PR feedback
* fix typo in geo-shape.asciidoc
* ignore circle test in docs
* update indexing-approach ref to geoshape-indexing-approach
* add warnings check for LegacyGeoShapeFieldMapper to AbstractBuilderTestCase

This commit exposes lucene's LatLonShape field as the
default type in GeoShapeFieldMapper. To use the new
indexing approach, simply set "type" : "geo_shape" in
the mappings without setting any of the strategy, precision,
tree_levels, or distance_error_pct parameters. Note the
following when using the new indexing approach:
* geo_shape query does not support querying by
MULTIPOINT.
* LINESTRING and MULTILINESTRING queries do not
yet support WITHIN relation.
* CONTAINS relation is not yet supported.
The tree, precision, tree_levels, distance_error_pct,
and points_only parameters are deprecated.
* Adds deprecation logging to ScriptDocValues#getValues.
First commit addressing issue #22919.
`ScriptDocValues#getValues` was added for backwards compatibility but no
longer needed. Scripts using the syntax `doc['foo'].values` when
`doc['foo']` is a list should be using `doc['foo']` instead.
* Fixes two build errors in #34279
* Removes unused import in ScriptDocValuesDatesTest
* Removes used of `.values` in example in diversified-sampler-aggregation.asciidoc
* Removes use of .values from painless test.
Part of #34279
* Updates tests to use `doc[foo]` syntax rather than `doc[foo].values`.
* Removes use of `getValues()` and replaces use of `doc[foo].values` with `doc[foo]`.
* Indentation fix.
* Remove unnecessary list construction at previous `getValues()` callsite in ScriptDocValues.GeoPoints.
* Update migration doc and add link to `getValue` in ScriptDocValues javadoc.
* Fix compile
* Fix javadoc issue
* Removes ScriptDocValues#getValues usage from painless whitelist.
* Lower fielddata circuit breaker default limit
Lower fielddata circuit breaker default limit from 60% to 40% as we have
moved to doc_values for most of the cases.
* merge master in
* update tests
* update docs
This commit gets rid of the 'NONE' and 'INFO' severity levels for
deprecation issues.
'NONE' is unused and does not make much sense as a severity level.
'INFO' can be separated into two categories: Either 1) we can
definitively tell there will be a problem with the cluster/node/index
configuration that can be resolved prior to upgrade, in which case
the issue should be a WARNING, or 2) we can't, because any issues would
be at the application level, for which the user should review the
deprecation logs and/or response headers.
In real deployments it is important that clusters are properly configured to
avoid accidentally forming multiple independent clusters at cluster
bootstrapping time. However we also expect to be able to unpack Elasticsearch
and start up one or more nodes without any up-front configuration, and have
them do their best to find each other and form a cluster after a few seconds.
This change adds a delayed automatic bootstrapping process to nodes that start
up with no relevant settings set to support the desired out-of-the-box
experience without compromising safety in properly-configured deployments.
This commit changes the format of the `hits.total` in the search response to be an object with
a `value` and a `relation`. The `value` indicates the number of hits that match the query and the
`relation` indicates whether the number is accurate (in which case the relation is equals to `eq`)
or a lower bound of the total (in which case it is equals to `gte`).
This change also adds a parameter called `rest_total_hits_as_int` that can be used in the
search APIs to opt out from this change (retrieve the total hits as a number in the rest response).
Note that currently all search responses are accurate (`track_total_hits: true`) or they don't contain
`hits.total` (`track_total_hits: true`). We'll add a way to get a lower bound of the total hits in a
follow up (to allow numbers to be passed to `track_total_hits`).

When building a query Lucene distinguishes two cases, queries that require to produce a score and queries that only need to match. We cloned this mechanism in the QueryBuilders in order to be able to produce different queries based on whether they need to produce a score or not. However the only case in es that require this distinction is the BoolQueryBuilder that sets a different minimum_should_match when a `bool` query is built in a filter context..
This behavior doesn't seem right because it makes the matching of `should` clauses different when the score is not required.
Closes#35293
MultiSearchRequests issues through `_msearch` now validate all keys
in the metadata section. Previously unknown keys were ignored
while now an exception is thrown.

We changed the way realm settings are defined, and this affects custom
realms in SecurityExtensions. This change adds those details to the
breaking changes docs.
Relates: #30241
This moves all Realm settings to an Affix definition.
However, because different realm types define different settings
(potentially conflicting settings) this requires that the realm type
become part of the setting key.
Thus, we now need to define realm settings as:
xpack.security.authc.realms:
file.file1:
order: 0
native.native1:
order: 1
- This is a breaking change to realm config
- This is also a breaking change to custom security realms (SecurityExtension)
In a future major version, we will be introducing a soft limit on the
number of shards in a cluster based on the number of nodes in the
cluster. This limit will be configurable, and checked on operations
which create or open shards and issue a warning if the operation would
take the cluster over the limit.
There is an option to enable strict enforcement of the limit, which
turns the warnings into errors. In a future release, the option will be
removed and strict enforcement will be the default (and only) behavior.
- Restrict visibility of Aggregators and Factories
- Move PipelineAggregatorBuilders up a level so it is consistent with
AggregatorBuilders
- Checkstyle line length fixes for a few classes
- Minor odds/ends (swapping to method references, formatting, etc)
When a envelope that crosses the dateline is specified as a part of
geo_shape query is parsed it shouldn't have its left and right points
flipped.
Fixes#34418
The `term` and `phrase` suggesters have different options to filter candidates
based on their frequencies. The `popular` mode for instance filters candidate
terms that occur in less docs than the original term. However when we compute this threshold
we use the total term frequency of a term instead of the document frequency. This is not inline
with the actual filtering which is always based on the document frequency. This change fixes
this discrepancy and clarifies the meaning of the different frequencies in use in the suggesters.
It also ensures that the threshold doesn't overflow the maximum allowed value (Integer.MAX_VALUE).
Closes#34282
This change disallows negative query boosts. Negative scores are not allowed in Lucene 8 so
it is easier to just disallow negative boosts entirely. We should also deprecate negative boosts
in 6x in order to ensure that users are aware when they'll upgrade to ES 7.

Relates to #31389
Changes the default of the `node.name` setting to the hostname of the
machine on which Elasticsearch is running. Previously it was the first 8
characters of the node id. This had the advantage of producing a unique
name even when the node name isn't configured but the disadvantage of
being unrecognizable and not being available until fairly late in the
startup process. Of particular interest is that it isn't available until
after logging is configured. This forces us to use a volatile read
whenever we add the node name to the log.
Using the hostname is available immediately on startup and is generally
recognizable but has the disadvantage of not being unique when run on
machines that don't set their hostname or when multiple elasticsearch
processes are run on the same host. I believe that, taken together, it
is better to default to the hostname.
1. Running multiple copies of Elasticsearch on the same node is a fairly
advanced feature. We do it all the as part of the elasticsearch build
for testing but we make sure to set the node name then.
2. That the node.name defaults to some flavor of "localhost" on an
unconfigured box feels like it isn't going to come up too much in
production. I expect most production deployments to at least set the
hostname.
As a bonus, production deployments need no longer set the node name in
most cases. At least in my experience most folks set it to the hostname
anyway.
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.
This change removes the wrapping of the created field in the put user
response. The created field was added as a top level field in #32332,
while also still being wrapped within the `user` object of the
response. Since the value is available in both formats in 6.x, we can
remove the wrapped version for 7.0.
The remote cluster settings search.remote.* have been renamed to
cluster.remote.* and are automatically upgraded in the cluster state on
gateway recovery, and on put. This commit adds a note to the migration
docs for these changes.
This change collapses all metrics aggregations classes into a single package `org.elasticsearch.aggregations.metrics`.
It also restricts the visibility of some classes (aggregators and factories) that should not be used outside of the package.
Relates #22868
The main benefit of the upgrade for users is the search optimization for top scored documents when the total hit count is not needed. However this optimization is not activated in this change, there is another issue opened to discuss how it should be integrated smoothly.
Some comments about the change:
* Tests that can produce negative scores have been adapted but we need to forbid them completely: #33309Closes#32899
In #29623 we added `Request` object flavored requests to the low level
REST client and in #30315 we deprecated the old `performRequest`s. In a
long series of PRs I've changed all of the old style requests. This
drops the deprecated methods and will be released with 7.0.
We used to set `maxScore` to `0` within `TopDocs` in situations where there is really no score as the size was set to `0` and scores were not even tracked. In such scenarios, `Float.Nan` is more appropriate, which gets converted to `max_score: null` on the REST layer. That's also more consistent with lucene which set `maxScore` to `Float.Nan` when merging empty `TopDocs` (see `TopDocs#merge`).
Currently, if geo context is represented by something other than
geo_point or an object with lat and lon fields, the parsing of it
as a geo context can result in ignoring the context altogether,
returning confusing errors such as number_format_exception or trying
to parse the number specifying as long-encoded hash code. It would also
fail if the geo_point was stored.
This commit makes the mapping parsing more strict and will fail during
mapping update or index creation if the geo context doesn't point to
a geo_point field.
