Hi Exerts, I have 3 indices > ``` > student (name=vg, gopal etc) > teacher (teachername=robert, bob etc) > Class (classname=maths, english etc) > > ``` What I want is to check student and teacher indices and based on a condition results I want to update school index something like if `name=vg , teachername= robert then class=maths` should be updater in Class index. This should be an automated process , so when data get into student , teacher index class modify accordingly ? Regards VG ---

No you can't do that. What are you trying to do exactly? I mean: don't speak about the implementation but only the use case. ---

Well , I have antivirus data , vulnerability data and Configuration data (cmdb) . Here requirement is if system affected with virus , also it is vulnerable then cmdb index should get update like it is critical system/machine .Second scenario would be if machines is affected but not vulnerable then it is low critical and so on.. ---

We recommend doing that at ingest time. Take the event, look in the AV index, then the vulnerability index, then the CMDB index and add things to the original event accordingly. ---
