# Class AssociationFacetField

java.lang.Object
org.apache.lucene.document.Field
org.apache.lucene.facet.taxonomy.AssociationFacetField

All Implemented Interfaces:
  `IndexableField`

Direct Known Subclasses:
  `FloatAssociationFacetField`, `IntAssociationFacetField`

public class AssociationFacetField extends Field
Add an instance of this to your `Document` to add a facet label associated with an arbitrary byte[]. This will require a custom `Facets` implementation at search time; see `IntAssociationFacetField` and `FloatAssociationFacetField` to use existing `Facets` implementations.

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