}Nested Object Mapping
Setting up a nested field is simple—where you would normally specify type
object, make it type nested instead:
-
A
nestedfield accepts the same parameters as a field of typeobject.
That’s all that is required. Any comments objects would now be indexed as
separate nested documents. See the
{ref}/nested.html[nested type reference docs] for more.
