How to query all predicates from one node by one predicate?

Hi @wwwjljj,

To get all predicates, you could use expand(_all_) . Note that to use expand, type system will have to be used. Also, to get the node using <类型> , the predicate <类型> will have to be indexed.

The query will then look something like this:

{
  get_all_predicates(func: eq(<类型>, "动作")) {
    expand(_all_)
  }
}
