I'm trying to do this (two level collapse)

but with top\_hits aggregation. Essentially I want to be able to have a collapse inside of the top\_hits aggregation but it's not supported.

Is there any way to make this work? The two level collapse works. I'm trying to see if I can get a better performance with top\_hits aggregation.

Thanks
