All Implemented Interfaces:

Writeable

public class PotentiallyUnmappedKeywordEsField
extends KeywordEsField

This class is used as a marker for fields that may be unmapped, where an unmapped field is a field which exists in the _source but is not mapped in the index. Note that this field may be mapped for some indices, but is unmapped in at least one of them. For indices where the field is unmapped, we will try to load them directly from _source.
