class |
DateHistogramAggregation
Date histogram aggregation.
|
class |
DateRangeAggregation
Date range aggregation.
|
class |
FilterAggregation
Aggregation used to narrow down the current query document space.
|
class |
GeoDistanceAggregation
Aggregation that aggregates the documents based on a
center point and a collection of ranges .This aggregation produces a result of type IGeoDistanceAggregationResult . |
class |
HistogramAggregation
Histogram aggregation.
|
class |
NestedObjectAggregation
This aggregation should be used mainly when some aggregations must be performed over fields inside a
nested object field .In this case, the aggregations should be added as sub-aggregations of a nested object aggregation .For example, suppose we have a person document type with the following fields:name (text) address (nested object) street (keyword) number (keyword) And there are 3 documents in this document type: {"name": "Nara Jones"} {"name": "Albert Russef", "address": [{"street": "Av Rio Branco", "number": "23"}, {"street": "Av Francisco Bicalho"}]} {"name": "Josef Camus", "address": [{"street": "Av Presidente Vargas"}]} If a filter aggregation must be created with a filter to restrict the documents to those with the field address.number ,
and this filter aggregation has a terms aggregation as sub aggregation, the terms aggregation result
will have the buckets Av Rio Branco and Av Francisco Bicalho , because, since there's no nested aggregation, both of them will be
considered in filter aggregation. |
class |
