* Add more missing AggregationBuilder getters
- getMetadata for all aggs
- various getters on TermsAggBuilder (without "get" prefix to maintain convention)
- Also makes InternalSum's ctor public, to follow suit of other metrics (min/max/avg/etc)

We want to upgrade to Lucene 7 ahead of time in order to be able to check whether it causes any trouble to Elasticsearch before Lucene 7.0 gets released. From a user perspective, the main benefit of this upgrade is the enhanced support for sparse fields, whose resource consumption is now function of the number of docs that have a value rather than the total number of docs in the index.
Some notes about the change:
- it includes the deprecation of the `disable_coord` parameter of the `bool` and `common_terms` queries: Lucene has removed support for coord factors
- it includes the deprecation of the `index.similarity.base` expert setting, since it was only useful to configure coords and query norms, which have both been removed
- two tests have been marked with `@AwaitsFix` because of #23966, which we intend to address after the merge

With this change we remove a TODO from CommonFields. Also this will be useful when parsing aggs response for the high level REST client.

It is no longer needed. It used to contain a lot of strings
used by serialization but those have since been removed. Now
it is just another thing to pass around that we don't really
need.
|
|
This class is just a wrapper around `SearchContext`, so let's use
`SearchContext` directly. The change is mechanical, except the
`ValuesSourceConfig` class, where I moved the logic to get a `ValuesSource`
given a config.

This is an attempt to start moving aggs parsing to `ObjectParser`. There is
still A LOT to do, but ObjectParser is way better than the way aggregations
parsing works today. For instance in most cases, we reject numbers that are
provided as strings, which we are supposed to accept since some client languages
(looking at you Perl) cannot make sure to use the appropriate types.

default script language.
** The default script language is now maintained in `Script` class.
* Added `script.legacy.default_lang` setting that controls the default language for scripts that are stored inside documents (for example percolator queries). This defaults to groovy.
** Added `QueryParseContext#getDefaultScriptLanguage()` that manages the default scripting language. Returns always `painless`, unless loading query/search request in legacy mode then the returns what is configured in `script.legacy.default_lang` setting.
** In the aggregation parsing code added `ParserContext` that also holds the default scripting language like `QueryParseContext`. Most parser don't have access to `QueryParseContext`. This is for scripts in aggregations.
* The `lang` script field is always serialized (toXContent).
Closes #20122

Adds `getAggregations` to `SearchPlugin` which can be used to register
aggregations.
Fixup MockNode which wasn't createing MockBigArrays.

AggregationBuilder, in keeping consistent with the Java APIs.
Closes #18377

Replace with writeNamedWriteable. s/write/read/g

Removes deprecated registration methods from SearchModule and
NamedWriteableRegistry and removes the "shims" used to migrate
aggregations to the new registration methods.

Aggregations need to perform instanceof calls on MappedFieldType instances in
order to know how they should be parsed or formatted. Instead, we should let
the field types provide a formatter/parser that can can be used.

collected
If a terms aggregation was ordered by a metric nested in a single bucket aggregator which did not collect any documents (e.g. a filters aggregation which did not match in that term bucket) an ArrayOutOfBoundsException would be thrown when the ordering code tried to retrieve the value for the metric. This fix fixes all numeric metric aggregators so they return their default value when a bucket ordinal is requested which was not collected.
Closes #17225

Also renamed histogram.AbstractBuilcer to AbstractHistogramBuilder, range.AbstractBuilder to AbstractRangeBuilder and org.elasticsearch.search.aggregations.pipeline.having to org.elasticsearch.search.aggregations.pipeline.bucketselector

ValuesSourceConfig is now evaluated in the ValuesSourceAggregatorFactory instead of ValueSourceParser. This means that the ValueSourceParser purely deals with parsing the XContent and the logic requiring access to the mappings etc. on the shard is left to the ValuesSourceAggregatorFactory. This means that, in the future, the parsing logic can be moved to the coordinating node.
|
|
This allows a lot of null checks to be removed where we were always falling back to the ValueFormat.RAW anyway. Now the format is set to ValueFormat.RAW when no alternative is suitable.
Closes #10594
