Re: [CAUTION] Converting graph query to stream graph query

[Natarajan, Rajeswari]

I need to gather all the children of docid  1 . Root item has parent as null. 
(Sample data below)

Tried as below

nodes(graphtest,
      walk="1->parent",
      gather="docid",
      scatter="branches, leaves")
      
Response :
{
  "result-set": {
    "docs": [
      {
        "node": "1",
        "collection": "graphtest,",
        "field": "node",
        "level": 0
      },
      {
        "EOF": true,
        "RESPONSE_TIME": 5
      }
    ]
  }
}

Query just gets the  root item and not it's children. Looks like I am missing 
something obvious . Any pointers , please.

As I said earlier the below graph query gets all the children of docid 1.

fq={!graph from=parent to=docid}docid:"1" 

Thanks,

    "commit" : {}
    }'
    
    
    For the above data , the below query gets all the children of document with 
docid 1.
    
    
http://localhost:8983/solr/graphtest/select?q=*:*&fq={!graph%20from=parent%20to=docid}docid:"1<http://localhost:8983/solr/graphtest/select?q=*:*&fq=%7b!graph%20from=parent%20to=docid%7ddocid:%221>"
    
    
    How can I convert this query into streaming graph query with nodes 
expression.
