Method Detail

getExclude

@Value.Default
default java.util.List<java.lang.Object> getExclude()

getExecutionHint

ExecutionHint getExecutionHint()

Returns the mechanism by which terms aggregation is executed.

Returns:

the mechanism by which terms aggregation is executed.

getInclude

@Value.Default
default java.util.List<java.lang.Object> getInclude()

getMinDocCount

java.lang.Long getMinDocCount()

Returns the minimum number of hits required before returning a term.

Returns:

the minimum number of hits required before returning a term.

getShardMinDocCount

java.lang.Long getShardMinDocCount()

Returns the minimum number of hits required on a local shard before a term is returned.

Returns:

the minimum number of hits required on a local shard before a term is returned.

getShardSize

java.lang.Long getShardSize()

Returns how many terms the coordinating node will request from each shard. Once all the shards responded, the coordinating node will then reduce them to a final result which will be based on the size parameter - this way, one can increase the accuracy of the returned terms and avoid the overhead of streaming a big list of buckets back to the client.

Returns:

the number of terms the coordinating node will request from each shard.

getSize

java.lang.Integer getSize()

Returns how many term buckets should be returned out of the overall terms list. By default, the node coordinating the search process will request each shard to provide its own top size term buckets and once all shards respond, it will reduce the results to the final list that will then be returned to the client.

Returns:

how many term buckets should be returned out of the overall terms list.

accept

default void accept(AggregationVisitor visitor)

Specified by:

accept in interface Aggregation
