We are seeing high SearchRate spike at a certain times in a day along with Index and Search latency. We are having a cluster of 6 nodes with 3 master ones and other 3 are data nodes with 200 GB EBS volume. Not able to figure out the exact reason for sudden increase in spike, could you please help what can be the reason for it and how to prevent it.
Also, for indices we are going with the default sharding mechanism(5 primary shards) and I believe this might be the reason for it.
