-------------------------------------
Summary: Allow nodes streaming expression to rank by inbound
degree of the node
Key: SOLR-15196
URL: https://issues.apache.org/jira/browse/SOLR-15196
Project: Solr
Issue Type: Improvement
Security Level: Public (Default Security Level. Issues are Public)
Reporter: Joel Bernstein
Currently the *nodes* graph expression only calculates inbound degree if the
count(\*) aggregation is applied to the function. This ticket will cause the
nodes function to always calculate inbound degree and return the nodes in
*inbound degree order*. A new *top* parameter will be added to only return the
top N nodes with the highest inbound degree. The *indegree* field will be added
to each node in the returned nodeset. The *scoreNodes* function will also be
changed to use the *indegree* field rather than the count(\*) field.
