Hi, I am able to get the child documents by using an index. But not by using an alias. This works: /cms\_articles\_v7/trending\_articles/\_search But this doesn't work: /cms\_articles/trending\_articles/\_search I use AWS ES. In the above cms\_articles\_v7 is an index and cms\_articles is an alias. trending\_articles is child type. I use ES 5.6 version. thanks Sri ---

Honestly, while I know you said the alias is set correctly - it certainly sounds like it isn't, by the problem description. No weird slight mispellings, dashes-hyphens differences in the alias names you've been trying and what's set up? ---
