I think this should be keyword?

Actually children is a list of children nodes, I don't think it is keyword type.

How are children named? It should be either keyword or text. Have a look to ES documentation:https://www.elastic.co/guide/en/elasticsearch/reference/current/array.html:
In Elasticsearch, there is no dedicated array type. Any field can contain zero or more values by default, however, all values in the array must be of the same datatypeThere was a problem hiding this comment.

children list is a ID list seperated by comma, looks like:
"children": "4,3,1,0"
I think it's much more like text. I will change its type from string to text.

ah thank you, I understand it now, would it make sense to split that string into an array of keywords?

Actually I display this children list in Grafana as a text, seems like there's no need to make them into an array of keyword now. If there's a need to make them into array in the future, I will pull a patch for it.
