Interface Summary

Interface	Description
Aggregation	An aggregation
Aggregations	Represents a set of computed addAggregation.
AggregationStreams.Stream	A stream that knows how to read an aggregation from the input.
Aggregator.Parser	Parses the aggregation request and creates the appropriate aggregator factory for it.
HasAggregations

Class Summary

Class	Description
AbstractAggregationBuilder	Base structure for aggregation builders.
AggregationBinaryParseElement
AggregationBuilder<B extends AggregationBuilder<B>>	A base class for all bucket aggregation builders.
AggregationBuilders	Utility class to create aggregations.
AggregationParseElement	The search parse element that is responsible for parsing the get part of the request.
AggregationPhase
AggregationStreams	A registry for all the dedicated streams in the aggregation module.
Aggregator	An Aggregator.
AggregatorBase	Base implementation for concrete aggregators.
AggregatorFactories
AggregatorFactories.Builder
AggregatorFactory	A factory that knows how to create an Aggregator of a specific type.
AggregatorParsers	A registry for all the aggregator parser, also servers as the main parser for the aggregations module
BucketCollector	A Collector that can collect data in separate buckets.
InternalAggregation	An internal implementation of Aggregation.
InternalAggregation.CommonFields	Common xcontent fields that are shared among addAggregation
InternalAggregation.ReduceContext
InternalAggregation.Type	The aggregation type that holds all the string types that are associated with an aggregation: name - used as the parser type stream - used as the stream type
InternalAggregations	An internal implementation of Aggregations.
InternalMultiBucketAggregation<A extends InternalMultiBucketAggregation,B extends InternalMultiBucketAggregation.InternalBucket>
InternalMultiBucketAggregation.InternalBucket
LeafBucketCollector	Per-leaf bucket collector.
LeafBucketCollectorBase	A LeafBucketCollector that delegates all calls to the sub leaf aggregator and sets the scorer on its source of values if it implements ScorerAware.
NonCollectingAggregator	An aggregator that is not collected, this can typically be used when running an aggregation over a field that doesn't have a mapping.
SearchContextAggregations	The aggregation context that is part of the search context.
ValuesSourceAggregationBuilder<B extends ValuesSourceAggregationBuilder<B>>	A base class for all bucket aggregation builders that are based on values (either script generated or field data values)

Enum Summary
