If it isn't, I can't use Nested approach and will have to consider parent/child. I have to eventually filter nested objects and sort them by different nested fields.

Nested objects, hits, inner hits and sorting

As an example imagine Mapping OuterObject contains nested NestedObject. Data OuterObject1 contains NestedObject1, NestedObject2 OuterObject2 contains NestedObject3, NestedObject4 Desired Results (using a nested filter) 4 hits OuterObject1 and NestedObject1 OuterObject1 and NestedObject2 OuterObject2 and NestedObject3 OuterObject2 and NestedObject4 If I use inner hits then the results look like this OuterObject1, inner_hits = NestedObject1, NestedObject2 OuterObject2, inner_hits = Nes…
