David Smiley updated SOLR-12122:
--------------------------------
Description:
The {{nodes}} streaming expression has a {{walk}} argument that articulates a
pair of Solr fields of the form {{traversalFrom->traversalTo}}. It assumed
that they are *not* multiValued. It _appears_ not difficult to add multiValued
support to traversalTo; that's what this issue is about.
See
http://lucene.472066.n3.nabble.com/Using-multi-valued-field-in-solr-cloud-Graph-Traversal-Query-td4324379.html
Note: {{gatherNodes}} appears to be the older name which is still supported.
It's more commonly known as {{nodes}}. graph-traversal.adoc documents it
was:
The {{gatherNodes}} streaming expression has a {{walk}} argument that
articulates a pair of Solr fields of the form {{traversalFrom->traversalTo}}.
It assumed that they are *not* multiValued. It _appears_ not difficult to add
