I am using kibana version 4.6.1 with elasticsearch version 2.2.0 and pumping logs via logstash/rsyslog.d on the client side. All my logs seem to land up in ES and show via kibana but I am getting intermittent issues on kibana when I search for logs that show "No results found". However if I keep refreshing the browser with no changes to the time span the results show up. Could this be a possible bug with the versions I am using? If not, any recommendations on how to troubleshoot this type of an intermittent issue. The network looks healthy and these servers (kibana & ES) don't seem to have any communication issues.
Thanks in advance for your assistance.
