Joel Bernstein updated SOLR-15196:
----------------------------------
Description: 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 descending *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. (was: Currently the *nodes* graph expression only calculates
