Hello! I'm really sorry if this is a noob question, but in my research I didn't find any solution to my problem. My ELK-Stack gets a lot JSON formed Activity Stream like data (xAPI). Sadly, they are sometimes very huge and have a special field called "extension" where arbitrary data can be included (object, number, string, more deep nested JSON objects). This "arbitrary" data is very interesting for my own analytics. Is there a way to insert those JSON Log strings and search for data? Please done hesitate to ask for further information if I've missed something! Many Thanks in advance! ---

Hello, I think I will solve my problem with `ignore_malformed: true` in my mapping. This just leads to other Problems for me. It's another topic so I will open a new one! ---
