Trees in CouchDB

Question

I am new to CouchDB and wondering.

I save posts with the parent id of the message as an attribute. A message can also have childMessage as its parent, so it looks like a tree.

How can I query all children, including children of children?

thank

CouchDB - . . , ?

:.

{
  "msg":"Parent message",
  "children":[
    {
       "msg":"sub message 1"
    },
    {
       "msg":"sub message 2",
       "children":[
         {
           "msg":"sub sub message 1"
         }
       ]
    }
  ]
}
