valueFetcher
Description copied from class:MappedFieldTypeCreate a helper class to fetch field values during theFetchFieldsPhase. New field types must implement this method in order to support the search 'fields' option. Except for metadata fields, field types should not throwUnsupportedOperationExceptionsince this could cause a search retrieving multiple fields (like "fields": ["*"]) to fail.- Specified by:
