Hi Joel, Thanks for your reply. This is a little different issue. Here the root docs have parent_id as null. The parent_id of the child will be the docid of the parent. With the data above and for the query below
nodes(s4, walk="1->parent_s", gather="docid_s", scatter="branches, leaves") Below results returned, the result doesn't contain second level children. { "result-set": { "docs": [ { "node": "1", "collection": "s4", "field": "node", "level": 0 }, { "node": "11", "collection": "s4", "field": "docid_s", "level": 1 }, { "node": "12", "collection": "s4", "field": "docid_s", "level": 1 }, { "node": "13", "collection": "s4", "field": "docid_s", "level": 1 }, { "EOF": true, "RESPONSE_TIME": 63 } ] } } Not sure how to map parent and docid and get all the children(docid) of a particular parent docid.
