thanks Joel. Running with /stream handler did reveal some issues and after fixing the same the gagtherNodes expr is working!! I am trying out the recommendations sample from solr website for my use case and now I am struck at the next step which is unable to get the top 3 of those nodes: curl --data-urlencode 'expr=top(n="30", sort="count(*) desc", nodes(rec_coll, search(rec_coll, q="35d40c4b9d6ddfsdf45cbb0fe4aesd75->USER_ID", fl="ITEM_ID", sort="ITEM_ID desc", qt="/export"), walk="ITEM_ID->ITEM_ID", gather="USER_ID", fl="USER_ID", maxDocFreq="10000", count(*)))' http://localhost:8983/solr/rec_coll/graph
Again appreciate any help.... Vidhya On Thu, Nov 8, 2018 at 1:23 PM Joel Bernstein <joels...@gmail.com> wrote: > The basic syntax looks ok.
