Joel, Thanks, I did try using cartesianProduct then fetch, it is working as excepted. For my dataset has only 5 or 6 level for that shortestPath response time is ~5 sec and with cartesianProduct and fetch I am getting ~6.5 sec. Is there any other way to achieve this?
For my use case graph query did work well but with SolrCloud, there is no guarantee that all the nodes will in the same shard.
