Is CloudSolrClient thread-safe?

for aggregations It is odd there would be quite such a big performance delta. What version of solr are you using? What is the fieldType of "grades"? -Yonik On Sun, Apr 30, 2017 at 5:15 AM, Mikhail Ibraheem <mikhail.ibrah...@oracle.com> wrote: > 1- > studentId has docValue
