* Added percolator field mapper that extracts the query terms and indexes these terms with the percolator query.
* At percolate time these extracted terms are used to query percolator queries that are like to be evaluated. This can significantly cut down the time it takes to percolate. Whereas before all percolator queries were evaluated if they matches with the document being percolated.
* Changes made to percolator queries are no longer immediately visible, a refresh needs to happen before the changes are visible.
* By default the percolate api only returns upto 10 matches instead of returning all matching percolator queries.
* Made percolate more modular, so that it is easier to add unit tests.
* Added unit tests for the percolator.

When specifying a string field, you can either do:
```
{
"foo": "bar"
}
```
or
```
{
"foo": {
"value": "bar",
"boost": 42
}
}
```
The latter option is now removed.
Closes#15388
Today we throttle recoveries only for incoming recoveries. Nodes that have a lot
of primaries can get overloaded due to too many recoveries. To still keep that at bay
we limit the number of threads that are sending files to the target to overcome this problem.
The right solution here is to also throttle the outgoing recoveries that are today unbounded on
the master and don't start the recovery until we have enough resources on both source and target nodes.
The concurrency aspects of the recovery source also added a lot of complexity and additional threadpools
that are hard to configure. This commit removes the concurrent streamns notion completely and sends files
in the thread that drives the recovery simplifying the recovery code considerably.
Outgoing recoveries are not throttled on the master via a allocation decider.
Today we have two variants of translogs for indexing. We only recommend the buffered
one which also has a 20% advantage in indexing speed. This commit removes the option and defaults
to the buffered case. It also hard-wires the translog buffer to 8kb instead of 64kb. We used to
adjust that buffer based on if the shard is active or not, this code has also been removed and
instead we just keep an 8kb buffer arround.
This option allows to force the xcontent type to use to store the `_source`
document. The default is to use the same format as the input format.
This commit makes this option ignored for 2.x indices and rejected for 3.0
indices.
As a replacement use ExistsQueryBuilder inside a mustNot() clause.
So instead of using `new ExistsQueryBuilder(name)` now use:
`new BoolQueryBuilder().mustNot(new ExistsQueryBuilder(name))`.
Closes#14112
throw exception if a copy_to is within a multi field
Copy to within multi field is ignored from 2.0 on, see #10802.
Instead of just ignoring it, we should throw an exception if this
is found in the mapping when a mapping is added. For already
existing indices we should at least log a warning.
We remove the copy_to in any case.

When using S3 or EC2, it was possible to use a proxy to access EC2 or S3 API but username and password were not possible to be set.
This commit adds support for this. Also, to make all that consistent, proxy settings for both plugins have been renamed:
* from `cloud.aws.proxy_host` to `cloud.aws.proxy.host`
* from `cloud.aws.ec2.proxy_host` to `cloud.aws.ec2.proxy.host`
* from `cloud.aws.s3.proxy_host` to `cloud.aws.s3.proxy.host`
* from `cloud.aws.proxy_port` to `cloud.aws.proxy.port`
* from `cloud.aws.ec2.proxy_port` to `cloud.aws.ec2.proxy.port`
* from `cloud.aws.s3.proxy_port` to `cloud.aws.s3.proxy.port`
New settings are `proxy.username` and `proxy.password`.
```yml
cloud:
aws:
protocol: https
proxy:
host: proxy1.company.com
port: 8083
username: myself
password: theBestPasswordEver!
```
You can also set different proxies for `ec2` and `s3`:
```yml
cloud:
aws:
s3:
proxy:
host: proxy1.company.com
port: 8083
username: myself1
password: theBestPasswordEver1!
ec2:
proxy:
host: proxy2.company.com
port: 8083
username: myself2
password: theBestPasswordEver2!
```
Note that `password` is filtered with `SettingsFilter`.
We also fix a potential issue in S3 repository. We were supposed to accept key/secret either set under `cloud.aws` or `cloud.aws.s3` but the actual code never implemented that.
It was:
```java
account = settings.get("cloud.aws.access_key");
key = settings.get("cloud.aws.secret_key");
```
We replaced that by:
```java
String account = settings.get(CLOUD_S3.KEY, settings.get(CLOUD_AWS.KEY));
String key = settings.get(CLOUD_S3.SECRET, settings.get(CLOUD_AWS.SECRET));
```
Also, we extract all settings for S3 in `AwsS3Service` as it's already the case for `AwsEc2Service` class.
Closes#15268.
Do not to load fields from _source when using the `fields` option.
Non stored (non existing) fields are ignored by the fields visitor when using the `fields` option.

Support * wildcard to retrieve stored fields when using the `fields` option.
Supported pattern styles are "xxx*", "*xxx", "*xxx*" and "xxx*yyy".
We actually want to keep the test when using deprecated setting in 3.0.
We will keep this setting deprecated as well so people will be able to update in a smoother way.
Also add the deprecating information to the migration documentation.
query_binary and filter_binary are unused at this point, as we only parse on the coordinating node and the java api only holds structured java objects for queries and filters, meaning they all implement Writeable and get natively serialized.

Removes the mapping transform feature which when used made debugging very
difficult. Users should transform their documents on the way into
Elasticsearch rather than having Elasticsearch do it.
Closes#12674
We have two types of parse methods for queries: one for the inner query, to be used once the parser is positioned within the query element, and one for the whole query source, including the query element that wraps the actual query.
With the search refactoring we ended up using the former in count, cat count and delete by query, whereas we should have used the former. It ends up working properly given that we have a registered (deprecated) query called "query", which used to allow to wrap a filter into a query, but this has the following downsides:
1) prevents us from removing the deprecated "query" query
2) we end up supporting a top level query that is not wrapped within a query element (pre 1.0 syntax iirc that shouldn't be supported anymore)
This commit finally removes the "query" query and fixes the related parsing bugs. We also had some tests that were providing queries in the wrong format, those have been fixed too.
Closes#13326Closes#14304
* Allow for multiple host specifications (e.g. _en0_,192.168.1.2,_site_).

The NotQueryBuilder has been deprecated on the 2.x branches
and can be removed with the next major version. It can be

This adds an API for force merging lucene segments. The `/_optimize` API is now
deprecated and replaced by the `/_forcemerge` API, which has all the same flags

This commit removes some cache concurrency level settings that were

but no longer apply with the cache implementation completed in #13717.

The `_create` API is handy way to specify an index operation should only be done if the document doesn't exist. This is currently implemented in explicit code paths all the way down to the engine. However, conceptually this is no different than any other versioned operation - instead of requiring a document is on a specific version, we require it to be deleted (or non-existent). This PR removes Engine.Create in favor of a slight extension in the VersionType logic.
There are however a couple of side effects:
- DocumentAlreadyExistsException is removed and VersionConflictException is used instead (with an improved error message)
- Update will reject version parameters if the upsert option is used (it doesn't compute anyway).
- Translog.Create is also removed infavor of Translog.Index (that's OK because their binary format was the same, so we can just read Translog.Index of the translog file)
Closes#13955
Types are still optional, but if you do provide them, they can't be null. Split the existing constructor that accepted nnull into two, one that accepts no arguments, and another one that accepts the types argument, which must be not null.
Also trimmed down different ways of setting ids, some were misleading as they would always add the ids to the existing ones and not set them, the add prefix makes that clear. Left `addIds` method that accepts a varargs argument. Added check for ids not be null.
TermsLookupQueryBuilder was left around only for bw comp reasons, but TermsQueryBuilder is its replacement. We can remove it now that it is clear query refactoring goes in master (3.0).
This commit fixes ping timeout settings inconsistencies in
ZenDiscovery. In particular, the documentation refers to the ping
timeout setting as discovery.zen.ping_timeout but the code was
ultimately using discovery.zen.ping.timeout if this was set.
This commit also changes all instances of the raw string
“discovery.zen.ping_timeout” to the constant
o.e.d.z.ZenDiscovery.SETTING_PING_TIMEOUT.
Finally, this commit removes the legacy setting
"discovery.zen.initial_ping_timeout".
Closes#6579, #9581, #9908
The current MoreLikeThisQueryBuilder validation checks for existence of at
least one `like` text or item. This is hard to check in setters, so this PR
tries to change the construction of the query so that we can do these checks
already at construction time.
Changing to using arrays for fieldnames, likeTexts, likeItems, unlikeTexts
and unlikeItems. `likeTexts` and/or `likeItems` need to be specified at
construction time to validate we have at least one item there.

Moving validation from validate() to constructors and setters for the
following query builders:
* GeoDistanceQueryBuilder
* GeoDistanceRangeQueryBuilder
* GeoPolygonQueryBuilder
* GeoShapeQueryBuilder
* GeohashCellQuery
* TermsQueryBuilder
Relates to #10217
This PR is the second batch in moving the query validation we started
to collect in the validate() method to the corresponding setters
and constructors.
Requesting a million hits, or page 100,000 is always a bad idea, but users
may not be aware of this. This adds a per-index limit on the maximum size +
from that can be requested which defaults to 10,000.
This should not interfere with deep-scrolling.
Closes#9311
* Dropped ScoreType in favour of Lucene's ScoreMode
* Removed `score_type` option from `has_child` and `has_parent` queries in favour for the already existing `score_mode` option.
* Removed the score mode `sum` in favour for the already existing `total` score mode. (`sum` doesn't exist in Lucene's ScoreMode class)
* If `max_children` is set to `0` it now really means that zero children are allowed to match.
This add equals, hashcode, read/write methods, separates toQuery and JSON parsing and adds tests.
Also moving MatchQueryBuilder.Type to MatchQuery to MatchQuery, adding serialization and hashcode,
equals there.
Relates to #10217
Previously the parser could take any Term Vectors request, but this would be
not the case of the builder which would still use MultiGetRequest.Item. This
introduces a new Item class which is used by both the builder and parser.
Beyond that the rest is mostly cleanups such as:
1) Deprecating the ignoreLike methods, in favor to using unlike.
2) Deprecating and renaming MoreLikeThisBuilder#addItem to addLikeItem.
3) Ordering the methods of MoreLikeThisBuilder more logically.
This change is needed for the upcoming query refactoring of MLT.
