Direct Known Subclasses:

TaxonomyFacetSumFloatAssociations, TaxonomyFacetSumValueSource

public class TaxonomyFacetFloatAssociations
extends FloatTaxonomyFacets

Aggregates float values associated with facet fields. Supports two different approaches:

1. Fields can be indexed with FloatAssociationFacetField, associating weights with facet values at indexing time.
2. Fields can be indexed with FacetField and a DoubleValuesSource can dynamically supply a weight from each doc. With this approach, the document's weight gets contributed to each facet value associated with the doc.

Aggregation logic is supplied by the provided FloatAssociationFacetField.

WARNING: This API is experimental and might change in incompatible ways in the next release.
