-----------------------------------
Summary: gatherNodes expression should support multiValued walk
target
Key: SOLR-12122
URL: https://issues.apache.org/jira/browse/SOLR-12122
Project: Solr
Issue Type: Improvement
Security Level: Public (Default Security Level. Issues are Public)
Components: streaming expressions
Reporter: David Smiley
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
multiValued support to traversalTo; that's what this issue is about.
