This change merges the functionality of the FiltersFunctionScoreQuery in the FunctionScoreQuery.
It also ensures that an exception is thrown when the computed score is equals to Float.NaN or Float.NEGATIVE_INFINITY.
These scores are invalid for TopDocsCollectors that relies on score comparison.

Extracts ranges from range queries on byte, short, integer, long, half_float, scaled_float, float, double, date and ip fields.
byte, short, integer and date ranges are normalized to Lucene's LongRange.
half_float and float are normalized to Lucene's DoubleRange.
When extracting range queries, the QueryAnalyzer computes the width of the range. This width is used to determine
what range should be preferred in a conjunction query. The QueryAnalyzer prefers the smaller ranges, because these
ranges tend to match with less documents.
Closes#21040
Today we expose `IndexFieldDataService` outside of IndexService to do maintenance
or lookup field data in different ways. Yet, we have a streamlined way to access IndexFieldData
via `QueryShardContext` that should encapsulate all access to it. This also ensures that we control all other functionality like cache clearing etc.
This change also removes the `recycler` option from `ClearIndicesCacheRequest` this option is a no-op and should have been removed long ago.
Today when we aggregate on the `_index` field the cross cluster search
alias is not taken into account. Neither is it respected when we search
on the field. This change adds support for cluster alias when the cluster
alias is present on the `_index` field.

This commit removes all external dependencies from the rest client jar

This change disables the graph analysis on default `shingle` filter.
The pre-configured shingle filter produces shingles of different size.
Graph analysis on such token stream is useless and dangerous as it may create too many paths.

This change rewrites search requests on the coordinating node before
we send requests to the individual shards. This will reduce the rewrite load
and object creation for each rewrite on the executing nodes and will fetch
resources only once instead of N times once per shard for queries like `terms`
query with index lookups. (among percolator and geo-shape)
Relates to #25791
Also has updates to ScriptMetaData for allowing the old namespace format to be loaded all the way back through 5.0; however, it will throw an exception if two scripts share the same id but different languages.
The `QueryRewriteContext` used to provide a client object that can
be used to fetch geo-shapes, terms or documents for percolation. Unfortunately
all client calls used to be blocking calls which can have significant impact on the
rewrite phase since it occupies an entire search thread until the resource is
received. In the case that the index the resource is fetched from isn't on the local
node this can have significant impact on query throughput.
Note: this doesn't fix MLT since it fetches stuff in doQuery which is a different beast. Yet, it is a huge step in the right direction
This commit calls the `useSystemProperties` method on the HttpAsyncClientBuilder so that the jvm
system properties are used. The primary reason for doing this is to ensure the builder uses the
system default SSLContext rather than the default instance created by the http client library.

Today we have duplicated code that is quite complicated to iterate
over rewriteable (`QueryBuilders` mainly) This change introduces a
`Rewriteable` interface that allow to share code to do the rewriting as
well as encapsulation and composition of queries.
We currently use fielddata on the `_id` field which is trappy, especially as we
do it implicitly. This changes the `random_score` function to use doc ids when
no seed is provided and to suggest a field when a seed is provided.
For now the change only emits a deprecation warning when no field is supplied
but this should be replaced by a strict check on 7.0.

This change refactors the query_string query to analyze the query text around logical operators of the query string the same way than a match_query/multi_match_query.
It also adds a type parameter that can be used to change the way multi fields query are built the same way than a multi_match query does.
Now that these queries share the same behavior regarding text analysis, some parameters are obsolete and have been deprecated:
split_on_whitespace: This setting is now ignored with a deprecation notice
if it is used explicitely. With this PR The query_string always splits on logical operator.
It simplifies the understanding of the other parameters that can have different meanings
depending on the value of split_on_whitespace.
auto_generate_phrase_queries: This setting is now ignored with a deprecation notice
if it is used explicitely. This setting only makes sense when the parser splits on whitespace.
use_dismax: This setting is now ignored with a deprecation notice
if it is used explicitely. The tie_breaker parameter is sufficient to handle best_fields/most_fields.

Closes#20248
Today if we search across a large amount of shards we hit every shard. Yet, it's quite
common to search across an index pattern for time based indices but filtering will exclude
all results outside a certain time range ie. `now-3d`. While the search can potentially hit
hundreds of shards the majority of the shards might yield 0 results since there is not document
that is within this date range. Kibana for instance does this regularly but used `_field_stats`
to optimize the indexes they need to query. Now with the deprecation of `_field_stats` and it's upcoming removal a single dashboard in kibana can potentially turn into searches hitting hundreds or thousands of shards and that can easily cause search rejections even though the most of the requests are very likely super cheap and only need a query rewriting to early terminate with 0 results.
This change adds a pre-filter phase for searches that can, if the number of shards are higher than a the `pre_filter_shard_size` threshold (defaults to 128 shards), fan out to the shards
and check if the query can potentially match any documents at all. While false positives are possible, a negative response means that no matches are possible. These requests are not subject to rejection and can greatly reduce the number of shards a request needs to hit. The approach here is preferable to the kibana approach with field stats since it correctly handles aliases and uses the correct threadpools to execute these requests. Further it's completely transparent to the user and improves scalability of elasticsearch in general on large clusters.
Requests that execute a stored script will no longer be allowed to specify the lang of the script. This information is stored in the cluster state making only an id necessary to execute against. Putting a stored script will still require a lang.
There is a bug when a call to `BytesReferenceStreamInput` skip is made
on a `BytesReference` that has an initial offset. The offset for the
current slice is added to the current index and then subtracted from the
length. This introduces the possibility of a negative number of bytes to
skip. This happens inside a loop, which leads to an infinte loop.
This commit correctly subtracts the current slice index from the
slice.length. Additionally, the `BytesArrayTests` are modified to test
instances that include an offset.
Currently when we close a channel in Netty4Utils.closeChannels we
block until the closing is complete. This introduces the possibility
that a network selector thread will block while waiting until a
separate network selector thread closes a channel.
For instance: T1 closes channel 1 (which is assigned to a T1 selector).
Channel 1's close listener executes the closing of the node. That
means that T1 now tries to close channel 2. However, channel 2 is
assigned to a selector that is running on T2. T1 now must wait until T2
closes that channel at some point in the future.
This commit addresses this by adding a boolean to closeChannels
indicating if we should block on close. We only set this boolean to true
if we are closing down the server channels at shutdown. This call is
never made from a network thread. When we call the closeChannels method
with that boolean set to false, we do not block on close.
This commit does two things:

Indexing ids in binary form should help with indexing speed since we would
have to compare fewer bytes upon sorting, should help with memory usage of
the live version map since keys will be shorter, and might help with disk
usage depending on how efficient the terms dictionary is at compressing
terms.
Since we can only expect base64 ids in the auto-generated case, this PR tries
to use an encoding that makes the binary id equal to the base64-decoded id in
the majority of cases (253 out of 256). It also specializes numeric ids, since
this seems to be common when content that is stored in Elasticsearch comes
from another database that uses eg. auto-increment ids.
Another option could be to require base64 ids all the time. It would make things
simpler but I'm not sure users would welcome this requirement.
This PR should bring some benefits, but I expect it to be mostly useful when
coupled with something like #24615.
Closes#18154
Transport profiles unfortunately have never been validated. Yet, it's very
easy to make a mistake when configuring profiles which will most likely stay
undetected since we don't validate the settings but allow almost everything
based on the wildcard in `transport.profiles.*`. This change removes the
settings subset based parsing of profiles but rather uses concrete affix settings
for the profiles which makes it easier to fall back to higher level settings since
the fallback settings are present when the profile setting is parsed. Previously, it was
unclear in the code which setting is used ie. if the profiles settings (with removed
prefixes) or the global node setting. There is no distinction anymore since we don't pull
prefix based settings.

QueryParseContext is currently only used as a wrapper for an XContentParser, so
this change removes it entirely and changes the appropriate APIs that use it so
far to only accept a parser instead.
This commit makes the use of the global network settings explicit instead
of implicit within NetworkService. It cleans up several places where we fall
back to the global settings while we should have used tcp or http ones.
In addition this change also removes unnecessary settings classes
These settings have not be working for a full major version since they
are not registered. Given that they are simply duplicates we can just remove
them.
Currently QueryParseContext is only a thin wrapper around an XContentParser that
adds little functionality of its own. I provides helpers for long deprecated
field names which can be removed and two helper methods that can be made static
and moved to other classes. This is a first step in helping to remove
QueryParseContext entirely.

* Remove the setting from the yml tests and replace with tests using
`join` field. We can't use the setting in yml tests without lots of
backflips but we have `ReindexParentChildTests` for the coverage.
There weren't tests for `join` field with reindex before this. Adding
these tests discovered #25363.

`index.version.created=V_5_6_0`. This test can be entirely removed
when legacy parent/child support is dropped from core.
* Port the yml tests that set _parent into integ tests so they
can set the index created version. These tests can be removed
when we drop support for _parent in core.
* Port a delete-by-query test for filtering based on type to an

Custom whitelists in Painless will need to allow classes to be augmented beyond the currently hard-coded Augmentation class tied to Painless directly. This change allows any class to specify an augmentation on a Painless struct using an appropriate static method. Changes to loading the whitelist have also been created to allow for this specification of a different class for augmentation.
Most notable changes:

- TopDocs.totalHits is now a long: LUCENE-7872
- QueryBuilder does not remove the boolean query around multi-term synonyms:
LUCENE-7878
- removal of Fields: LUCENE-7500
For the `TopDocs.totalHits` change, this PR relies on the fact that the encoding
of vInts and vLongs are compatible: you can write and read with any of them as
long as the value can be represented by a positive int.
The `document_type` parameter is no longer required to be specified,
because by default from 6.0 only a single type is allowed. (`index.mapping.single_type` defaults to `true`)

I'm still trying to hunt down rare failures in the cancelation tests
for reindex and friends. Here is the latest:
https://elasticsearch-ci.elastic.co/job/elastic+elasticsearch+5.x+multijob-unix-compatibility/os=ubuntu/876/console
It doesn't show much, other than that one of the tasks didn't kill
itself when asked to cancel.
So I'm going a bit crazy with debug logging so that the next time this
comes up I can trace exactly what happened.
Additionally, this tweaks the logic around how rethrottles were
performed around cancel. Previously we set the `requestsPerSecond`
to `0` when we cancelled the task. That was the "old way" to set them
to inifity which was the intent. This switches that from `0` to
`Float.MAX_VALUE` which is the "new way" to set the `requestsPerSecond`
to infinity. I don't know that this is much better, but it feels better.
This change adds tests for the aggregation parsing that try to simulate that we
can parse existing aggregations in a forward compatible way in the future,

Today TcpTransport is the de-facto base-class for transport implementations.
The need for all the callbacks we have in TransportServiceAdaptor are not necessary
anymore since we can simply have the logic inside the base class itself. This change
moves the stats metrics directly into TcpTransport removing the need for low level
bytes send / received callbacks.
Moves the keyword tokenizer to the analysis-common module. The keyword tokenizer is special because it is used by CustomNormalizerProvider so I pulled it out into its own PR. To get the move to work I've reworked the lookup from static to one using the AnalysisRegistry. This seems safe enough.

* Add a section named "relation" in the ParentJoinFieldMapper
This commit puts the parent/child definition in an inner section named "relation".
Mapping for the parent-join will look like this:
```
"join_field": {
"type": "join"
"relations":
"parent": "child"
}
}
```
to specify a `targetField`. This results in some interesting behavior that was missed in the review.
This processor sorts in-place, so there is a side-effect in both the original field and the target field.
Another bug was that the targetField was not being set if the list being sorted was fewer than two elements.
The new behavior works like this: If targetField and fieldName are not the same, we copy the list.
We use assertBusy in many places where the underlying code throw exceptions. Currently we need to wrap those exceptions in a RuntimeException which is ugly.
This commit adds a NamedXContentProvider interface that can

This commit renames the needsScores method so as to make it
automatically generatable, based on the name of the `_score` variable
which is available in search scripts. It also adds documentation to
ScriptContext to explain the naming and signature of such methods.
Expose the experimental simplepattern and
simplepatternsplit tokenizers in the common
analysis plugin. They provide tokenization based
on regular expressions, using Lucene's
deterministic regex implementation that is usually
faster than Java's and has protections against

Both have a not-very-useful default pattern of the
empty string because all tokenizer factories must
be able to be instantiated at index creation time.
They should always be configured by the user
in practice.
Today if a channel gets closed due to a disconnect we notify the response
handler that the connection is closed and the node is disconnected. Unfortunately
this is not a complete solution since it only works for published connections.
Connections that are unpublished ie. for discovery can indefinitely hang since we
never invoke their handers when we get a failure while a user is waiting for
the response. This change adds connection tracking to TcpTransport that ensures
we are notifying the corresponding connection if there is a failure on a channel.
Get mappings HEAD requests incorrectly return a content-length header of

Today when an exception is thrown handling a HEAD request, the body is
swallowed before the channel has a chance to see it. Yet, the channel is
where we compute the content length that would be returned as a header
in the response. This is a violation of the HTTP specification. This
commit addresses the issue. To address this issue, we remove the special
handling in bytes rest response for HEAD requests when an exception is
thrown. Instead, we let the upstream channel handle the special case, as
we already do today for the non-exceptional case.

This commit adds back "id" as the key within a script to specify a
stored script (which with file scripts now gone is no longer ambiguous).
It also adds "source" as a replacement for "code". This is in an attempt
to normalize how scripts are specified across both put stored scripts and script usages, including search template requests. This also deprecates the old inline/stored keys.
This change removes the `postings` highlighter. This highlighter has been removed from Lucene master (7.x) because it behaves
exactly like the `unified` highlighter when index_options is set to `offsets`:
https://issues.apache.org/jira/browse/LUCENE-7815
It also makes the `unified` highlighter the default choice for highlighting a field (if `type` is not provided).
The strategy used internally by this highlighter remain the same as before, it checks `term_vectors` first, then `postings` and ultimately it re-analyzes the text.
Ultimately it rewrites the docs so that the options that the `unified` highlighter cannot handle are clearly marked as such.
There are few features that the `unified` highlighter is not able to handle which is why the other highlighters (`plain` and `fvh`) are still available.
I'll open separate issues for these features and we'll deprecate the `fvh` and `plain` highlighters when full support for these features have been added to the `unified`.

The `scorerSupplier` API allows to give a hint to queries in order to let them
know that they will be consumed in a random-access fashion. We should use this
for aggregations, function_score and matched queries.
Previously the HEAD and GET aliases endpoints were misaigned in
behavior. The HEAD verb would 404 if any aliases are missing while the
GET verb would not if any aliases existed. When HEAD was aligned with
GET, this broke the previous usage of HEAD to serve as an existence
check for aliases. It is the behavior of GET that is problematic here
though, if any alias is missing the request should 404. This commit
addresses this by modifying the behavior of GET to behave in this
way. This fixes the behavior for HEAD to also 404 when aliases are
missing.

This change moves the parent_id query to the parent-join module and handles the case when only the parent-join field can be declared on an index (index with single type on).

* All public methods starting with get will be added as local variables
to the execute method.
* The execute method on a ScriptContext must be both public and
abstract. This method will be implemented by the Painless compiler.
* A static list of parameter names for the execute method must be
provided since the names will be eliminated at runtime.
* The uses$ methods will still be implemented as before.
* A single constructor may be provided by the ScriptContext. This
constructor will be overridden by the Painless compiler to include the
exact same arguments. This allows instances of a Painless script to
potentially contain state. If a constructor is not provided it is
assumed the default constructor with no arguments will be used.
This removes the `accumulateExceptions()` method (and its usage) from `TransportNodesAction` and `TransportTasksAction`, forcing both transport actions to always accumulate exceptions.
Without this change, some transport actions, like `TransportNodesStatsAction` would respond in very unexpected ways by returning no response due to some failure, but instead of returning an
error the response would simply be empty: no response and no error.
This results in a very trappy response structure where users can check for an error, then attempt to blindly use the response when no error is returned.
* Adds nodes usage API to monitor usages of actions
The nodes usage API has 2 main endpoints
/_nodes/usage and /_nodes/{nodeIds}/usage return the usage statistics
for all nodes and the specified node(s) respectively.
At the moment only one type of usage statistics is available, the REST
actions usage. This records the number of times each REST action class is
called and when the nodes usage api is called will return a map of rest
action class name to long representing the number of times each of the action
classes has been called.
Still to do:
* [x] Create usage service to store usage statistics
* [x] Record usage in REST layer
* [x] Add Transport Actions
* [x] Add REST Actions
* [x] Tests
* [x] Documentation
* Rafactors UsageService so counts are done by the handlers
* Fixing up docs tests
* Adds a name to all rest actions
* Addresses review comments
This change ensures that there is a single parent-join field defined per mapping.
The verification is done through the addition of a special field mapper (MetaJoinFieldMapper) with a unique name (_parent_join) that is registered to the mapping service
when the first parent-join field is defined. If a new parent-join is added, this field mapper will clash with the new one and the update will fail.
This change also simplifies the parent join fetch sub phase by retrieving the parent-join field without iterating on all fields in the mapping.
This commit adds an optional `context` url parameter to the put stored
script request. When a context is specified, the script is compiled
against that context before storing, as a validation the script will
work when used in that context.
* Introduce ParentJoinFieldMapper, a field mapper that creates parent/child relation within documents of the same index
This change adds a new field mapper named ParentJoinFieldMapper. This mapper is a replacement for the ParentFieldMapper but instead of using the types in the mapping
it uses an internal field to materialize parent/child relation within a single index.
This change also adds a fetch sub phase that automatically retrieves the join name (parent or child name) and the parent id for child documents in the response hit fields.
The compatibility with `has_parent`, `has_child` queries and `children` agg will be added in a follow up.

ScriptContexts currently understand a FactoryType that can produce
instances of the script InstanceType. However, for search scripts, this
does not work as we have the concept of LeafSearchScript that is created
per lucene segment. This commit effectively renames the existing
SearchScript class into SearchScript.LeafFactory, which is a new,
optional, class that can be defined within a ScriptContext.
LeafSearchScript is effectively renamed back into SearchScript. This
change allows the model of stateless factory -> stateful factory ->
script instance to continue, but in a generic way that any script
context may take advantage of.

This brings it inline with the classes purpose.
This commit adds collection of all contexts to the parameters of
getScriptEngine. This will allow script engines like painless to
precache extra information about the contexts.
This is a simple refactoring to move the context definitions into the
type that they use. While we have multiple context names for the same
class at the moment, this will eventually become one ScriptContext per
instance type, so the pattern of a static member on the interface called
CONTEXT can be used. This commit also moves the consolidated list of
contexts provided by core ES into ScriptModule.
This commit changes the compile method of ScriptEngine to be generic in
the same way it is on ScriptService. This moves the shim of handling the
two existing context classes into each script engine, so that each
engine can be worked on independently to convert to real handling of
contexts.
This commit modifies the compile method of ScriptService to be context
aware. The ScriptContext is now a generic class which contains both the
instance type and compiled type for a script. Instance type may be
stateful (for example, pre loading field information for the index a
script will execute on, like in expressions), while the compiled type is
stateless and used to construct instance type instances. This change is
only a first step to cutover ScriptService to the new paradigm. It only
converts callers to the script service, and has a small shim to wrap
compilation from the script engines to support the current two fixed
instance types, SearchScript and ExecutableScript.
Since groovy was removed, we no longer have any ScriptEngines with
resources to release. We may want to keep the option open for a script
engine to close resources, but this would not be common. This commit
adds a default implementation to ScriptEngine for `close()` to reduce
the boiler plate that must be added for a ScriptEngine implementation.
This will be useful for the high level client to add support for the matrix stats aggregation, as we will ship with this jar by default like we do for parent-join-client which is aligned with distributing core with the modules already included.

As we work towards contexts implying the return type of compilation, we
first need ScriptContext to not be an enum. This commit removes the
Standard enum and Plugin subclass of ScriptContext.
ScriptEngine implementations have an overridable method to indicate they
are safe to use as inline scripts. Since groovy was removed fro 6.0,
there are no longer any implementations which used the default false
value. Furthermore, the value was not actually read anywhere. This
commit removes the method. The ScriptEngineRegistry was also no longer
necessary as it only was used to build a map from language to engine.
Allows plugins to register pre-configured tokenizers. Much
of the decisions are the same as those in #24223, #24572,

This change removes the field data specialization needed for the parent field and replaces it with

Now this change moves it to the latest released version of 5.x (5.4 at this point)
to ensure we are compatible with the latest minor of the previous major. This change
also removes all the `_UNRELEASED` from the versions that where released and drops versions
that were never released and are not expected to be released (bugfixes in minors that are not
the latest in the previous major).
We've switched to supporting only `yml` files but anyone who didn't
notice will commit a `yaml` file which won't be executed
which is bad because it is easy not to notice. The test to catch this is
simple enough that I think it is worth adding just to warn folks about
their mistake.
These tests are broken because I added them with the `yml` extension
and didn't realize that we weren't running tests with that extension
until we merged #24659. I used that extension in anticipation of #24659
but didn't verify that the tests were actually running. Ooops!
Closes#24734
This commit renames all rest test files to use the .yml extension
instead of .yaml. This way the extension used within all of
elasticsearch for yaml is consistent.
Moves the remaining preconfigured token figured into the analysis-common module. There were a couple of tests in core that depended on the pre-configured token filters so I had to touch them:
* `GetTermVectorsCheckDocFreqIT` depended on `type_as_payload` but didn't do anything important with it. I dropped the dependency. Then I moved the test to a single node test case because we're trying to cut down on the number of `ESIntegTestCase` subclasses.
* `AbstractTermVectorsTestCase` and its subclasses depended on `type_as_payload`. I dropped their usage of the token filter and added an integration test for the termvectors API that uses `type_as_payload` to the `analysis-common` module.
* `AnalysisModuleTests` expected a few pre-configured token filtes be registered by default. They aren't any more so I dropped this assertion. We assert that the `CommonAnalysisPlugin` registers these pre-built token filters in `CommonAnalysisFactoryTests`
* `SearchQueryIT` and `SuggestSearchIT` had tests that depended on the specific behavior of the token filters so I moved the tests to integration tests in `analysis-common`.
Today when an index is `read-only` the index is also blocked from
being deleted which sometimes is undesired since in-order to make
changes to a cluster indices must be deleted to free up space. This is
a likely scenario in a hosted environment when disk-space is limited to switch
indices read-only but allow deletions to free up space.
Range queries with now based date ranges were previously not allowed,
but since #23921 these queries were allowed. This change should really
fix range queries with now based date ranges.
Template script engines (mustache, the only one) currently return a
BytesReference that users must know is utf8 encoded. This commit
modifies all callers and mustache to have the template engine return
String. This is much simpler, and does not require decoding in order to
use (for example, in ingest).
Netty removed a logging guarded we added to prevent a scary logging
message. We added a hack to work around this. They've added the guard
back, so we can remove the hack now.
When constructing an array list, if we know the size of the list in
advance (because we are adding objects to it derived from another list),
we should size the array list to the appropriate capacity in advance (to
avoid resizing allocations). This commit does this in various places.

* Add parent-join module
This change adds a new module named `parent-join`.
The goal of this module is to provide a replacement for the `_parent` field but as a first step this change only moves the `has_child`, `has_parent` queries and the `children` aggregation to this module.
These queries and aggregations are no longer in core but they are deployed by default as a module.

Today we prune transport handlers in TransportService when a node is disconnected.
This can cause connections to starve in the TransportService if the connection is
opened as a short living connection ie. without sharing the connection to a node
via registering in the transport itself. This change now moves to pruning based
on the connections cache key to ensure we notify handlers as soon as the connection
is closed for all connections not just for registered connections.

If the request asks for the `_source` stored field then don't
duplicate it when forcing the `_source` parameter to onto the
request for reindex-from-remote from versions before 1.0.
