I recently realized that query performance is much better in the 2nd attempt than the initial attempt in Kibana dashboard .
Query Duration 5056ms Request Duration 5257ms Hits 1863206 Index "openstack-*"
Query Duration 320ms Request Duration 528ms Hits 1863245 Index "openstack-*"
Is there a cache in Query or Fetch phase that stays around for a while after the initial request?
My Kibana and elasticsearch version are both 5.1.1.
