…_values disabled (elastic#78841) (elastic#79462) The FieldNamesFieldMapper adds non-indexed fields to a special metadata field so that exists queries can be run efficiently. This is built in a postParse method that is run once per document. However, this means that nested documents are not handled correctly - non-indexed field names are added to the parent document's metadata field rather than to the nested document's field. This commit fixes things to add non-indexed field names directly to the nested documents. Co-authored-by: Yoann Rodière <yoann@hibernate.org>

The FieldNamesFieldMapper adds non-indexed fields to a special metadata
field so that exists queries can be run efficiently. This is built in a postParse
method that is run once per document. However, this means that nested
documents are not handled correctly - non-indexed field names are added to
the parent document's metadata field rather than to the nested document's
field.
This commit fixes things to add non-indexed field names directly to the
nested documents.
