Kibana not showing small magnitude of errors

[surajwy]

I have a very strange issue, if i create 3-4 error (i.e small in number), and send using logstash to elasticsearch and then finalliy view it using kibana then its not shown at all.
Now if i start shooting errors at high rate say 2/sec for next 10 seconds, then everything starts showing up in kibana, event those small ones fired before.
