Method Detail

getSubsetDf

public long getSubsetDf()

Specified by:

getSubsetDf in interface SignificantTerms.Bucket

Returns:

The number of docs in the subset containing a particular term. This number is equal to the document count of the bucket.

getSupersetDf

public long getSupersetDf()

Specified by:

getSupersetDf in interface SignificantTerms.Bucket

Returns:

The number of docs in the superset containing a particular term (also known as the "background count" of the bucket)

getSupersetSize

public long getSupersetSize()

Specified by:

getSupersetSize in interface SignificantTerms.Bucket

Returns:

The numbers of docs in the superset (ordinarily the background count of the containing aggregation).

getSubsetSize

public long getSubsetSize()

Specified by:

getSubsetSize in interface SignificantTerms.Bucket

Returns:

The numbers of docs in the subset (also known as "foreground set"). This number is equal to the document count of the containing aggregation.

getDocCount

public long getDocCount()

Specified by:

getDocCount in interface MultiBucketsAggregation.Bucket

Returns:

The number of documents that fall within this bucket

getAggregations

public Aggregations getAggregations()

Specified by:

getAggregations in interface MultiBucketsAggregation.Bucket

Specified by:

getAggregations in interface HasAggregations

Returns:

The sub-aggregations of this bucket

reduce

public B reduce(java.util.List<B> buckets,
                InternalAggregation.ReduceContext context)

getSignificanceScore

public double getSignificanceScore()

Specified by:

getSignificanceScore in interface SignificantTerms.Bucket

Returns:

The significant score for the subset

toXContent

public final XContentBuilder toXContent(XContentBuilder builder,
                                        ToXContent.Params params)
                                 throws java.io.IOException

Specified by:

toXContent in interface ToXContent

Throws:

java.io.IOException

keyToXContent

protected abstract XContentBuilder keyToXContent(XContentBuilder builder)
                                          throws java.io.IOException

Throws:

java.io.IOException
