Hi Yonik, Thanks for pointing out the difference.
I've made modification and tried with this below command for JSON Facet, but it is still having a QTime of 410, as compared to the Legacy Facet QTime of 22: http://localhost:8983/solr/collection1/select?q=paint&json.facet={f:{field:content}}&rows=0 Is this the same as the Legacy Facet query of http://localhost:8983/solr/collection1/select?q=paint&facet=true&facet.field=content&rows=0 <http://27.54.41.220:8983/edm/collection1/select?q=paint&facet=true&facet.field=content&rows=0> ?
